5 PREFACE Due to the increase in traffic, the Danish Parliament decided in January 2001 to widen Motorway 3 which is a city motorway that runs through a heavily populated area around Copenhagen. The construction work started in April 2005 and ended in November Great efforts were made to reduce the noise exposure from road traffic for the many thousand neighbours who live a short distance from the motorway in connection with the widening of the 17 km long motorway section from two to three lanes in each direction between Jægersborgvej and Holbækmotorvej. As a part of the project, an investigation on noise annoyance due to road traffic noise was carried out by the Danish Road Directorate. The investigation was designed as a pre and post-study which contains the responses from people who live in the residential areas along Motorway 3. Subjective responses were collected by means of two mail questionnaires carried out before the widening in 2003 and a year after the construction work was finalized in This report describes the investigation and presents the results obtained. It must be emphasised that data collected by means of a questionnaire survey is the participants own perception and report. The responses are from six selected housing areas along the motorway. The criteria for the development of socio-acoustic surveys that have been applied in this survey derive from the work of the International Commission on Biological Effects of Noise - ICBEN [1]. The project was carried out by a group mainly consisting of researchers from the Danish Road Directorate. The design of the questionnaire survey, including the questionnaire itself, was discussed in 2003 with an expert group with the following members: Lene Mikkelsen, Danish Road Directorate Hans Bendtsen, Danish Road Directorate / Danish Road Institute Bent Andersen, Danish Road Directorate / Danish Road Institute Lars Ellebjerg Larsen, Danish Road Directorate / Danish Road Institute Niels Gottlieb, Danish Road Directorate Hanne Lylov Nielsen, Environmental Protection Agency Jørgen Horstmann, Environmental Protection Agency Torben Poulsen, Acoustic Technology, Denmark Technical University Marie Louise Bistrup, National Institute of Public Health 5

6 Torben Holm Petersen, Delta Acoustic and Vibration Ivan Christensen, Municipality of Gladsaxe Ib Skovgaard, Municipality of Herlev Aslak Fyhri, The Institute of Transport Economics, Oslo The pre-questionnaire survey has been carried out by the consulting company Atkins Denmark, while the post-questionnaire survey has been carried out six years later by the Danish Road Directorate by the same experts who carried out the pre-questionnaire earlier; at that time Hans Bendtsen, Bent Andersen, Lars Ellebjerg Larsen were employed at Atkins Denmark. For many years, the noise indicator L Aeq,24h has been used in Denmark when assessing noise from road traffic. A new indicator, L DEN, was introduced by the Environmental Protection Agency in The noise mapping for the M3 project was performed using the noise indicator L Aeq,24h. All the noise levels presented in this report are A-weighted. The unit db is used in this report and it is equal to what is often denoted db(a) or dba. The noise calculations were carried out by Lars Find Larsen from COWI. The data analyses were carried out with valuable feedback from Hans Bendtsen. The report is written by Emine Celik Christensen with comments from Hans Bendtsen. Proof reading of the final report and translation (Danish-English) of the questionnaire, cover letter and reminder were made by Helen Hasz-Singh. The authors gratefully acknowledge the valuable comments and recommendations of the expert group in the design of the questionnaire and contribution to the pilot testing. The authors would also like to thank all respondents for participating and making this study possible. 6

7 SUMMARY Due to the increase in traffic, the Danish Parliament decided to widen Motorway 3 (M3) from four to six lanes on a 17 km long stretch in January By 2005, the traffic volume was 90,000 vehicles/day. M3 is an urban motorway that runs through a heavily populated area around Copenhagen. In a belt of 500 metres on both sides of the motorway around 14,000 dwellings are located meaning that around 30,000 people live along the motorway. Before the widening of M3, there were metres high noise barriers. As part of the reconstruction project, four meter high noise barriers were built and noise reducing road pavements were laid. A detailed noise map showed that if the previously constructed low noise barriers along the M3 were kept until 2010, there would have been approximately 6,300 dwellings exposed to more than 55 db of noise from the motorway traffic. However, by 2010, after the M3 was widened to six lanes and new noise barriers were constructed, only approximately 2,200 dwellings were actually exposed to noise higher than 55 db from the motorway. As a part of this widening process, an investigation on noise annoyance from road traffic noise has been carried out by Danish Road Directorate before and after the construction. The investigation was designed as a pre and post-study containing responses from the people living along the motorway in six residential areas with some 1,200 dwellings situated at distances from a few metres to metres from M3. Subjective responses were collected by two mail questionnaires that were sent out during the period of October-November 2003 and November-December 2009 respectively. The response rate was 71% in the pre-study and 65% in the post -study which can be considered quite high for this type of public questionnaires. Detailed noise calculations in the six selected investigation areas show that M3 is the main source of high noise levels. The noise exposure from other main roads and local roads in the six areas is considerably lower. In the aftersituation, no households are exposed to more than 60 db; while in the presituation 5% were exposed to more than 60 db. In the pre-situation, 45% of the population was exposed to noise levels between db, and this is significantly reduced to 22% in the post-situation. Around 50% of all dwellings were under 55 db in the pre-situation and this has increased to around 78% in the post-situation after the widening of the M3. 7

8 The description of the respondents in the pre and the post-study can be summarized as the following: All live in a villa or a terraced house. 90% own their own dwelling. Over 60% have lived in their dwelling for more than ten years. In the post-study, the respondents have lived longer in their dwelling. 70% of the respondents reports having a normal sensitivity to noise. In the post-study, there is a tendency towards higher incomes. Both in the pre and post-study, 10% have plans to move. 38% of the respondents stated that they participated to the pre-study On that background it has been decided that the population of respondents in the pre and the post-study are relatively alike and therefore it is reasonable to compare the results from the two studies. As a start to the questionnaire, the respondents got a general question on annoyance from road traffic. It is clear that noise is the dominant source of annoyance. Before the widening of the M3, 83% of the respondents highlighted noise as a source of annoyance and this reduces to 68% after the construction process. The percentage of respondents who do not experience any annoyance is increased form 10% to 20%. When the respondents were asked if the noise had changed during the last two to three years, 27% in the post-study answered that the noise has been reduced, and 44% think it is more or less unchanged. In the post-study 22% think the noise has increased and this is an improvement from the pre-study where 58% stated that the noise had increased during the latest two to three years. The main result of the two studies is the changes in the generally perceived noise annoyance from road traffic in the whole area including noise from M3 as well as local roads and other main roads. The percentage of very and extremely annoyed respondents decreases from 37% to 16%. The percentage of moderately annoyed is nearly constant with 30% and 27% respectively. Finally, the percentage of slightly or not annoyed increases from 33% to 57% from the pre to the post-study. As a total this is a remarkable reduction of the perceived noise annoyance in the areas studied around M3 for the new situation after the extension of M3. The questionnaire shows that M3 is the main source noise annoyance. After the widening, the perceived noise from M3 decreases while other major roads and local roads became more obvious. 8

9 There is a reduction of the reported annoyance and disturbance in the poststudy. In the pre-study, 38% reported that they opened the windows less than normal; this has decreased to 28% in the post-study. In the questions on sleeping quality there is a remarkable improvement. In the pre-study 14% reported difficulties in falling asleep or being woken up during night time. This has decreased to app. 7% in the post-study. For all activities related to being outside in the garden, there is a decrease in the reported annoyance in the post-study. The percentage of people who indicate annoyance during conversations is reduced from 36% to 20%. The percentage who indicate annoyance while reading outside decreases from 42% to 29% and finally the percentage annoyed while using the telephone is reduced form 19% to 12%. More than 70% of the respondents were not planning to move from their houses and there is no change between the percentages of respondents who is planning to move. Twenty three percent reported that traffic noise was the main reason for having plans to move in the pre-study and this decreased to 14% in the post-study. The respondents were asked what should be done to reduce the annoyance from road traffic noise. The percentage of respondents who recommend that nothing should be done increased from 13% to 28%, the percentage of respondents who recommended to build noise barriers decreased from 61% to 28%, while the percentage of respondents suggesting to use noise reducing noise pavements decreased from 61% to 40%. Response distribution shows that a large majority of the respondents (app. 70%) did nothing themselves to reduce noise annoyance where they live. Installing noise reducing windows is the second most common answer (15% to 20%). The increase in the installation of noise reducing windows after the widening of M3 may partly be explained by the Danish Road Directorate s offer to subsidize sound insulation of building façades. A large majority of the respondents (more than 70%) see it as the responsibility of the authorities to reduce noise. Most of the respondents are not at all eager to pay themselves to reduce noise. But there is a certain willingness to pay from 23% to 24%. There are 23% who in the pre-study do not know whether they would be willing to do so and this decrease to 18% in the post-study. Thirty percent of the respondents have actively participated in the process/discussion about the rebuilding of M3, while 40% did not want to do so. Eighteen percent of the respondents claimed they did not get the possibility to participate. 9

10 Fifty eight percent of the respondents found that the way the Danish Road Directorate communicates with them as resident in connection with the widening of M3 satisfactory or very satisfactory. The percentage of respondents who found the communication less satisfactory is only 8%. Both subjective noise annoyance responses and objective noise level calculations showed that there has been a great improvement in the environment along M3 as regards noise. Although the number of daily vehicles passing on M3 has increased significantly compared to six years ago, with the help of combined noise abatement solutions, noise levels have decreased and overall subjective responses on noise annoyance from traffic noise have significantly reduced. 10

11 CHAPTER 1 INTRODUCTION 1. INTRODUCTION In modern times, road traffic noise is recognized as a serious environmental problem which raises several aspects in the general public s awareness with regard to the increasing number of vehicles circulating on urban road network. Road traffic noise is a typical example of conflict between the needs for individual mobility and the desire for a quieter lifestyle. Noise is known as one of the most frequently reported negative environmental effects of traffic. It has been estimated that about 30% of the population in Denmark is exposed to road traffic noise at levels exceeding 55 db. Road traffic is the main source of transport noise in urban areas. To achieve an effective road traffic noise policy requires a combined approach that balances overall road-related sound emission without affecting citizens right to mobility. 1.1 BACKGROUND During the 1960 s, due to Denmark s post-war economic boom, the traffic on M3 which was a smaller road around Copenhagen was growing significantly. In order to relieve some of the traffic congestion from this road, the Danish Parliament decided to construct a new road. The new road is called shortly M3. M3 is situated approximately 15 km west of the centre of Copenhagen in Denmark and runs almost parallel between Ring Road 3 and Ring Road 4 (Figure 1.1 and Figure 1.2) 11

12 CHAPTER 1 INTRODUCTION Figure 1.1. Map of Copenhagen (left), M3 ( Motorring 3 in Danish) connecting the Danish capital Copenhagen to the rest of Denmark and Europe through six motorways (right). Figure 1.2. Bird eye view over M3. 12

13 CHAPTER 1 INTRODUCTION The construction of the M3 was decided in 1954 and was started in Figure 1.3 shows a view from M3 around 1960 s. Figure 1.3. M3, a few years after the construction started, in 1960 s. 13

14 CHAPTER 1 INTRODUCTION The section between Jægersborg and Jyllingevej was opened in 1968/71. In 1977, a new section connecting it to Holbækmotorvej was built. All the stages, in which the construction of the M3 was completed [2] are shown in Figure 1.4. Figure 1.4. Stages showing construction of M3. 14

15 CHAPTER 1 INTRODUCTION M3 connects the growing suburban areas, the city centre and other motorways which connect Denmark with the rest of the Europe [3]. Therefore, a few years after the construction was completed, it became the most important road around Copenhagen. However, over the last 25 to 30 years, traffic on the M3 has increased considerably to the point where long queues occurred during rush hours and vehicle speeds slowed down to km per hour. During the 1980 s, there were approximately vehicles a day on the M3, during 1990 s this number increased to and in 2005, there were more then vehicles a day on the M3 [4]. Due to the increase of traffic volume, it became necessary to find a new solution. The Danish Road Directorate carried out a detailed investigation aiming to solve the growing problem. On the basis of this investigation, the widening of the existing two-lane motorway to three lanes in each direction for 17 km was considered and chosen as the best solution among the alternatives [3]. An idea sketch of the solution chosen can be seen in Figure 1.5. Figure 1.5. Idea sketch of the widening of M3 from two to three lanes in each direction. During the widening process, one of the challenges was to keep the motorway functional throughout the entire four year construction period (Figure 1.6). 15

16 CHAPTER 1 INTRODUCTION Figure 1.6. Construction work on M3 during the widening During the construction, 235 properties were partly and 15 properties were fully expropriated. Additionally, 314 properties were used as temporary working areas for a limited period of time (see Figure 1.7). 16

17 CHAPTER 1 INTRODUCTION Figure 1.7. Some of the properties were used as temporary working areas for a limited period of time during the widening of M3. A close communication process was created between Danish Road Directorate and inhabitants living along M3 while the construction was on-going, which made it possible for inhabitants to comment on the process to some extent (Chapter 2). 17

18 CHAPTER 1 INTRODUCTION Figure 1.8. M3 after widening; Denmark s first architecturally designed motorway [5]. 1.2 EARLIER RESEARCH Annoyance from noise is affected by both individual and noise-source related factors. Individual factors are noise sensitivity, attitude to the noise source, physiological and psychological state, and situational factors such as activities performed or intended to be performed. Noise-source related factors are controllability of the noise source, information content and permanence. Hence, the same noise may result in totally different responses and reactions from different people depending on cultural factors [6], attitude to the noise source [7] and [8], noise sensitivity [8], controllability of the source [9], and other situational and individual aspects (see e.g. [10] and [11] for a review). Predicting a community s reaction to urban traffic noise is not easily made, based only on simple quantitative measures. To process suitable descriptors for the subjective judgment of noise exposure by means of simple objective measures is not easy to fulfill when individual differences come into play. Several attempts have therefore been made with the goal of correlating subjective annoyance and noise exposure [12], [13] and [14]. After reviewing numerous surveys, Shultz was able to synthesis a single curve for the relationship between community reaction and noise exposure [15]. 18

19 CHAPTER 1 INTRODUCTION When attempting to measure the degree of annoyance caused by traffic noise, the questionnaires and interviews to be answered by the responders and the test volunteers are also important. There are several models for such questionnaires. In the present study, the development of the survey derived from the work of the International Commission on Biological Effects of Noise [1]. 1.3 OBJECTIVE OF THE INVESTIGATION There have been few Danish surveys covering the subject of annoyance from traffic noise [16], [17]. The first survey dates back to the early 1970 s; since then, society has changed significantly which might have resulted in a change of the actual noise situation as well as people s tolerance to noise. In 2002, a large survey covering three urban areas in Odense, Randers and Århus was published [17]. The aims of the present investigation are; To find out what is the differences in annoyance levels before and after the widening of M3 To obtain a better knowledge on how people are annoyed by road traffic noise To provide up-to-date knowledge on noise annoyance To analyze the noise annoyance in various situations, which people experience during the day. Therefore it was decided to carry out a questionnaire survey covering the selected areas of interest. 19

20 CHAPTER 2 COMMUNICATION PROCES 2. COMMUNICATION PROCES M3 passes through a number of residential areas in which about 14,000 housing units are located in a range of about 500 metres each side of the road. This means about 30,000 people live close to M3. During the whole process from the earliest to the last phases of the project, communication with the public was taken very seriously and resources have been allocated by the Danish Road Directorate. There has been a full time communication employee working on the project who could be accessed by the neighbours all day. The public received continuous information about the progress of the project via public hearings, neighbour and company forums, information letters and an internet homepage. The Danish Road Directorate has carried out two public project hearings. Each hearing consisting of a number of informational meetings and debates, where citizens could make remarks and comment on the project (Figure 2.1). An introductory hearing was held during the idea and proposal phase of the project. A final hearing with the results of the plan for the M3 was also held. In addition, a number of informational meetings were held between the two hearings. Figure 2.1. Public project hearings, where citizens can make remarks and comment on the project. 20

21 CHAPTER 2 COMMUNUCATION PROCES Annoyance from traffic noise has often been the most important topic at the meetings. Suggestions and alternative solutions have been discussed during these meetings. To ensure a high level of communication between the Danish Road Directorate and the public, a neighbourhood forum was set up. In the forum there have been about 50 participants such as stakeholders and property owners, which meet two to four times a year to discuss issues and concerns on the M3 project. The forum was also used by the neighbours to influence the design of the noise barrier for the M3, and the type of plants that covers the barriers along each residence etc. These meetings enabled the Danish Road Directorate to give information on the progress of the project and to receive relevant feedback from local authorities and the public. Similar information meetings were also set up for the companies in the areas along the road having more than 100 employees. Danish Road Directorate has sent out letters to each household when there would be work in their area (along M3). It has also been possible to find updated information at the homepage of Danish Road Directorate on the work along M3. Figure 2.2. Construction work along M3 demolition of an old bridge.

23 CHAPTER 3 NOISE ABATEMENT 3. NOISE ABATEMENT 3.1 NOISE MAPPING The issue of traffic noise was the greatest concern of the neighbours living close to M3. Therefore, an extremely important part of the project has been to reduce the noise exposure for the inhabitants living along M3. To evaluate the noise related consequences, noise mapping along M3 was carried out in 2002 as a part of the Environmental Impact Assessment (see Figure 3.1). With noise mapping, noise exposure was calculated along M3. The calculations made it possible to evaluate the noise related consequences while changing a number of parameters such as traffic load, speed limits as well as implementing different noise reducing solutions. The construction price of different noise reducing solutions was evaluated for their effects so the noise related effect per invested DKK could be calculated. Based on the results of these calculations it was decided to use primarily four metre high noise barriers, wherever there was a need [18]. A detailed noise map showed that if the former old and low noise barriers along the M3 were kept until 2010, there would have been approximately 6,300 dwellings (housing units) exposed to more than 55 db of noise from the motorway traffic. In 2010, when the widening of the M3 was completed to six lanes and new noise barriers were built, only approximately 2,200 dwellings would be exposed to over 55 db noise from the motorway. 23

Noise mapping along M3 was carried out in 2002 as a part of the Environmental Impact Assessment. 3.2 NOISE BARRIER Before the widening of M3, there were noise barriers in the form of old eternite panels that were metres high (see Figure 3.2). In a few places there were newer barriers of about 3 metres in height, and in other places there was no noise protection at all. 24

26 CHAPTER 3 NOISE ABATEMENT During the widening process, approximately 24 million Euros have been spent on noise abatement. This includes building more than 17 km of noise barriers at a height of 2-4 metres along the road. The noise barriers in many sections include a foundation on a retaining wall, therefore the total height in some places is nine metres above the adjacent residential areas (see Figure 3.3 Figure 3.4 and Figure 3.5). Figure 3.3. Noise barriers in many sections include a foundation on a retaining wall. 26

30 CHAPTER 3 NOISE ABATEMENT In order to have both efficient and economic long lasting solutions, the Danish Road Directorate put high demands for the selection criteria of noise barriers. These were: high efficiency at reducing and absorbing noise long durability installation and maintenance from road side reasonable price (10-12 mio. DKK/km) Figure 3.7. Construction work seen from the road side. To give access to sunlight some housing areas had a noise barrier where the upper metres of the barrier are transparent (Figure 3.8). Transparent noise barriers have been used in the majority of locations and especially on the bridges. 30

31 CHAPTER 3 NOISE ABATEMENT Figure 3.8. At some places the upper part of the noise barriers were made from transparent acrylic plates. The top sections of the noise barriers were designed with a tilted 10 towards M3 (Figure 3.9, Figure 3.10 and Figure 3.11). The barriers were constructed of 75 cm wide elements of perforated aluminium covering a core of absorbing mineral wool which prevents the noise from being reflected to neighbours, living on the opposite side of the road. The neighbouring side of the noise barriers was covered with espalier for plants which suits the wishes of the neighbours. 31

As can be seen in Figure 3.12 and 3.13, on the bridges over crossing roads the noise barriers were made only from transparent modules for the bridges to look less massive as seen from the road crossing below. 33

35 CHAPTER 3 NOISE ABATEMENT 3.3 NOISE REDUCING PAVEMENTS It has been decided to use a special type of road surface (noise reducing thin layer pavement) on M3 which reduced the noise by 2-3 db compared to a standard reference pavement (Figure 3.14). The noise reducing effect has been obtained by using a smaller size of stone than usual in the asphalt mix. Furthermore, there were small cavities on the surface which let the air pressure created by the tires, get away from the surface pavement more silently. Figure A special type of road surface (noise reducing thin layer pavement) on M3 reduced the noise by 2-3 db compared a standard reference pavement. 3.4 SOUND INSULATION OF BUILDING FACADE Mounting noise barriers alone cannot provide sufficient noise protection in all places along the M3 e.g. buildings in several levels. Thus there has been a need for supplementing the sound insulation of building façades. In order to pinpoint relevant housing areas for supplementary sound insulation, new noise calculations were carried out in 2006, where designed noise barriers and the noise reducing pavement was a part of the input to the calculations. Danish Road Directorate offered to subsidize sound insulation of building facades for all the houses along the M3, which have been built before 1 st April 1984, exposed to noise above 60 db and having legal permission to be used all the year round. An additional condition was that a noise consultant must visit the house to describe what needs to be done in each house. Subsidies range between 50-90% of the entire noise reducing insulation costs to a maximum amount DKK per dwelling. Obtaining a quotation from a contrac- 35

36 CHAPTER 3 NOISE ABATEMENT tor had to be done by the house owner. Subsidies were paid after approval had been obtained from the Danish Road Directorate. The conditions were described in detail in [19]. In total, 135 residences were offered subsidies for sound insulation of their building façade. Figure 3.15 shows en example of a building having façade insulation in the form of glass covering of the balcony. By using the noise abatement methods that have been described above, significant improvements of the noise condition after the widening of M3 have been obtained. Figure Buildings with façade insulation such as glass covering of the balcony. 36

37 CHAPTER 4 MATERIAL AND METHODS 4. MATERIAL AND METHODS The noise annoyance investigation was a pre and post-study, containing the response from people who live along M3 and are exposed to noise from the motorway. Subjective responses were collected by two mail questionnaires that were carried out in the periods October-November 2003 and November- December The pre-study was carried out in a period where it was known by the public that the M3 motorway would be widened to six lanes and where the first public hearings had been organized. The post-study was conducted around a year after the construction work including the noise abatement measures was finished. Noise levels from road traffic were calculated at the same periods when the pre and post-questionnaires were sent out. This chapter describes the material and methods used to carry out the investigation. In the following subsections; selection criteria of the study area/sample, development, pilot testing, distribution of the questionnaire, noise level calculations and statistical treatment of the data will be given. CONSIDERATIONS: Pre and post-questionnaire enquiries were carried out at the same season (late autumn, early winter) of the year letting people answer the questions under similar physical conditions (open versus closed windows). Post-questionnaires have been sent out one year after the widening of M3 was completed. This gave people the possibility to experience the noise environment after the traffic and the urban conditions have normalized. The postquestionnaire can be seen in English translation in Appendix A and in the original Danish version in Appendix B. Only persons over the age of 18 years were asked to fill in the questionnaire. Both pre and post-questionnaires were sent to all the addresses that are primarily used for residence in each of the selected areas. It was clearly stated in the covering letter that the unanswered questionnaire should be returned in the enclosed pre-paid envelope by putting a tick on the letter, if the house at the address was used for business purposes. 4.1 STUDY AREA AND STUDY SAMPLE This section gives an introduction to the survey areas to which the questionnaires were sent. The criterion for the selection of residential areas was that each area should comprise; House type (single family detached houses, terraced houses) No apartment blocks Sound propagation from M3 (unscreened, screened, planted trees) 37

38 CHAPTER 4 MATERIAL AND METHODS With/without noise contribution from another large main road With/without change of noise contribution from M3 due to the widening of the motorway East/West of M3 (frequency of wind from different directions) No industrial or commercial areas, or areas dominated by shops and similar buildings It was decided to include six residential areas in order to give a good representation and fulfil the above criteria as well as possible. Figure 4.1 illustrates the location of the six survey areas from A to F. A B C D E MOTORVEJ E47/E55 MOTORVEJ E47/E55 MOTORVEJ E47/E55 F Figure 4.1. Map where survey areas from A to F are shown. The areas belong to Gladsaxe, Herlev og Rødovre municipalities. 38

39 CHAPTER 4 MATERIAL AND METHODS For all of the six areas, app 50% of the houses were primarily one floor (with a basement) single-family detached houses. AREA A Area A is situated in Bagsværd just northwest of the M3 and is further bounded by Gladsaxe Møllevej, Buddinge Hovedgade, Vibevænget, Rylevænget, Grævlingestien and Hermelinvænget. The accommodation is primarily singlefamily detached houses and terraced houses between Grævlingestien and Espegårdsvej. M3 in this area is placed on a high embankment and has a 1.8 metres high barrier of eternite plates in the pre-situation. The distance from the M3 to the nearest accommodation is approx. ten metres, the furthest it is around 450 metres from the motorway. Seven to eight hundred metres from the area in the western direction is the Hillerød motorway and the area is bounded towards East by Buddinge Hovedgade, which has considerable traffic load. (Response rate: pre-questionnaire 77.5%, post-questionnaire; 60.6%). Typical pictures from area after the widening are shown in Figure 4.2. Figure 4.2. Typical pictures from area A after the widening of the M3. 39

40 CHAPTER 4 MATERIAL AND METHODS AREA B The area is in Søborg just southeast of the M3, and just southeast of area A. The area is limited by Udmarken, Buddinge Hovedgade, Stengårds Allé, Klausdalsbrovej, Gladsaxe Møllevej, Ræveholmen, Rensdyrvej and Mårvænget. There are some terraced houses, but mostly the accommodation consists of single-family detached houses. The M3 in area B is on an embankment with a noise barrier of 1.8 metres in the pre-situation. The distance to the nearest accommodation is approx. 10 metres and to the furthest accommodation approx. 520 metres. The area is divided into two by Buddinge Hovedgade and Gladsaxe Møllevej. (Response rate: pre-questionnaire 70%, post-questionnaire; 60.9%). Typical pictures from area after the widening are shown in Figure 4.3. Figure 4.3. Typical pictures from area B after the widening of M3. 40

41 CHAPTER 4 MATERIAL AND METHODS AREA C Area C is situated in Herlev west of the M3 and southeast of Herlev Ringvej. The area is limited by Kagså, Ring 3, Tornerosevej, Elverparken, Nøkkedalen, and Hyldemorsvej. The southern part of the area is dominated by a large area of terraced houses and there is also an area of terraced houses in the northern corner. The remainder consists of single-family detached houses. A large part of the area is on a slope, which faces the M3. There are no noise barriers in the pre- situation. The house closest to the M3 is 75 metres away and the furthest house is 625 metres away. (Response rate: pre-questionnaire 76%, post-questionnaire; 68%). Typical pictures from the area after the widening are shown in Figure 4.4. Figure 4.4. Typical pictures from area C after the widening of M3. 41

42 CHAPTER 4 MATERIAL AND METHODS AREA D Area D is situated just south of area C, on the other side of Elverparken. Apart from the park, the area is limited by Ederlandsvej, Kagså, the M3, Herlev Hovedgade, Hyrdindestien and Tornerosevej. The area is dominated by single-family detached houses and a few terraced houses. Apart from M3 which is situated on an embankment and is in the pre-situation protected on a part of the stretch by a noise barrier of 1.8 metres height, the nearest roads are Herlev Hovedgade and Ring 3, both highly busy major roads. The house closest to the M3 is approx. 15 metres away, and the house furthest away is approx. 750 metres away. (Response rate: pre-questionnaire 66.5%, postquestionnaire; 66.8%). Typical pictures from the area after the widening are shown in Figure 4.5. Figure 4.5. Typical pictures from area D after the widening of M3. 42

43 CHAPTER 4 MATERIAL AND METHODS AREA E Area E lies in Mørkhøj, east of the M3 and directly across from area D. The area is limited by M3, Stavnsbjerg Allé, Ilbjerg Allé and Lillegårds Allé. The area only has single-family detached houses. The area is relatively protected from noise from other major roads. However, Mørkhøjvej is just a few rows of houses away. The nearest house is 70 metres from the M3, and the furthest house is 875 metres away. (Response rate: pre-questionnaire 68%, postquestionnaire; 66%). Typical pictures from the area after the widening are shown in Figure 4.6. Figure 4.6. Typical pictures from area E after the widening of M3. 43

44 CHAPTER 4 MATERIAL AND METHODS AREA F The area is in Rødovre on the other side of the Vestvolden with regard to M3, and thus in the pre situation protected from noise by the earthwork and the green areas. Apart from Vestvolden, the area is limited by Ejbyvej, Grønnemarksvej, Ringstrupvej, Bjødstrupvej, Borgmester Gustav Jensens Vej, Korsdalsvej and Rødovre Parkvej. The southern part of the area has terraced houses, whereas the area north of Lucernevej mainly consists of single-family detached houses. Tårnvej, which apart from the M3 is the only major road nearby, is some 100 metres from the area. The nearest houses are 280 metres from the motorway and those furthest away are 850 metres away. (Response rate: pre-questionnaire 66%). The post questionnaire has not been conducted in this area since there has been a delay in construction work because of an ongoing planning on how to connect the road to another new motorway. Typical pictures from the area after the widening are shown in Figure 4.7. Figure 4.7. Typical pictures from area F after the widening of M3. 44

45 CHAPTER 4 MATERIAL AND METHODS 4.2 QUESTIONNAIRE In this section the method for designing and conducting the questionnaire survey is presented. The structure and content of the questionnaire is described. Pilot testing, distribution process and data processing are explained in detail. As previously mentioned, the English translation of the questionnaire and the original Danish version are included as Appendix A and B respectively with their accompanying covering letter and reminder STRUCTURE AND CONTENT The questionnaire survey derived from an international standard [1] and was further developed with support of a group of experts (see Preface for the names of the members of the expert group). The draft questionnaire was sent to the expert group for their comments and their comments were used to improve the questionnaire further. The questionnaire employed both numerical and verbal scales. A 10-point rating scale was used to indicate satisfaction with the home or neighbourhood, and to rate bother, annoyance, disturbance caused both by noise in general and specifically noise from M3. The scale ranked from 0 to 10, where 0 was equivalent to not at all annoyed and 10 equivalent to extremely annoyed [1]. Noise sensitivity was also measured on a five-point verbal scale from 1= very insensitive to 4= very sensitive in both pre and post-questionnaires. The questions on annoyance from road traffic noise were posed as: "Thinking about the last 12 months when you are at home, how much does noise from.bother, disturb, or annoy you?" The question was a Danish translation of the question proposed in [1]. The same phrase was used to ask about annoyance indoors but with reference to open and closed window. Questions were also posed on how long the respondents had lived at their present address, the number of members in their family, age, gender and household income. The questions in the questionnaire filled six full A3 pages. The questionnaire was printed in black on two folded and stapled sheets of white paper, making a small booklet. Apart from the questionnaire itself, the respondents received a covering letter explaining that the survey was a part of a comprehensive investigation carried out by the Danish Road Directorate. The aim of the investigation was explained in the letter together with some practical information such as the deadline for returning the questionnaire and who should completed it (by a grown-up person over 18 years of age living in the dwelling). It was clearly stated that the Danish Road Directorate guarantees that all personal information will be treated in full confidence. 45

46 CHAPTER 4 MATERIAL AND METHODS Pre-questionnaire (October-November 2003) The pre-questionnaire survey was carried out by Atkins Denmark for the Danish Road Directorate in the period October-November In total 1,200 questionnaires covering six neighbourhoods (A, B, C, D, E and F) were distributed in three municipalities namely; Rødovre, Herlev, Gladsaxe (see Figure 4.1). Reminders were sent out to households that had not responded after three weeks. The response percentage was 63.6% before reminder letters were sent out. A total of 848 responses corresponding to 70.7% were received after the reminder was sent. The questionnaire included 43 questions which have been divided into six sections namely: 1) annoyance from road traffic in general 2) noise annoyance from road traffic specifically 3) noise from other roads 4) facts/conditions about respondent s residence 5) what can be done tp reduce road traffic noise 6) information on respondents themselves Of the 43 questions, fourteen questions were presented to the respondents with an additional response category other, where the respondents could specify their definition of other. The final question of the questionnaire was reserved to allow respondents to give their overall comments. All written answers and comments were treated manually. Post-questionnaire (November-December 2009 ) Six years after the first survey, in the period November-December 2009, a post-questionnaire survey has been carried out by the Danish Road Directorate. This questionnaire survey employed the same methodology as the first survey. In total, 986 questionnaires covering five neighbourhoods were distributed to three municipalities (Rødovre, Herlev, Gladsaxe) to the same addresses that were used in the first investigation (Figure 4.8). Households not responding after three weeks received an additional reminder. In total, 636 responses, corresponding to 64.5% were received after the reminding letter had been sent out. The reason why the questionnaire was only distributed to five areas instead of six is that the road construction work in Area F was postponed for a significant period to allow time for the planning of how to connect the road to neighbouring roads. Fourteen properties that were expropriated during the widening of M3 were also excluded during the post-study. 46

47 CHAPTER 4 MATERIAL AND METHODS Figure 4.8. Post-questionnaires ready to be posted, October 2009 The questionnaire included forty seven questions. In order to be able to compare results and have information about the widening, a new section (widening of M3) consisting of four questions was added to the post-questionnaire. One of these questions was about whether the respondent had participated to the previous enquiry regarding the widening of M3. The other three questions were about communication between the respondents and the Danish Road Directorate/contractors during the planning phase and the construction process. Out of forty seven questions, sixteen questions were presented to the respondents with a response category other PILOT TESTING In order to validate the survey procedure and to ensure that instructions were clear and specific, a pre-pilot test with project group members and a pilot test with 35 subjects was carried out prior to each questionnaire survey. Final adjustments were made after the pilot testing DISTRIBUTION All the questionnaires were sent to private addresses on the same day by national mail delivery together with a covering letter and a pre-paid envelop (see Figure 4.9). The questionnaires were all individually numbered, allowing the answers to be linked to calculated noise levels (L Aeq,24 ) at the individual addresses and reminder letters. 47

48 CHAPTER 4 MATERIAL AND METHODS Figure 4.9. Questionnaire, covering letter, pre-paid envelope DATA PROCESSING All the questionnaires returned were checked manually before they were sent for optical scanning. The optical scanning was carried out by the Danish IT Centre for Education and Research (UNI-C). This ensured fewer errors than if the responses were typed manually into a database. The coding procedure was also carried out by UNI-C. In order to ensure that the data and coding is correct, randomly selected questionnaires have also been checked manually. Data from scanned questionnaires were saved as SPSS (a commercial statistical analysis software program) data files. 4.3 CALCULATIONS OF NOISE EXPOSURE Before the widening of M3, noise level calculations have been carried out for the selected six residential areas (A, B, C, D, E, F - see Figure 4.1) by using a 3D calculation model that is built into SoundPLAN version 6.2. In the model, input data regarding information on ground, road construction, traffic, noise barriers and buildings was based on Road Directorate s digital ground planner (DGP), digital map and height models. The noise level calculations were based on the common Danish version of the Nordic calculation method for road traffic noise (NBV96) [20], [21], [22] and [23]. The calculations were made before NORD2000 was introduced as the mandatory new prediction method. 48

49 CHAPTER 4 MATERIAL AND METHODS Noise level calculations for pre-study were carried out with traffic quantity and speed from year 2000, which corresponds to the traffic model that was used in relation to Environmental Impact Assessments (EIA) that was carried out by the Danish Road Directorate in For post-study noise level calculations, the addresses in the residential areas from A to E were delivered by the Danish Road Directorate. The investigation contained 986 addresses in total. Based on National Survey and Cadastre calculated addresses coordinates (CAC), the relevant building polygons have been appointed in the digital base map. The individual building polygons were split into façade parts and a calculation point at a distance of two metres from the façade in the middle of each façade part was made. A minimum façade length of 4 metres has been decided to avoid calculation points at smaller building offsets etc. The calculation points have been numbered so the point (façade) facing M3 and having the shortest distance to M3 is given index 1. The following points are indicated clockwise. An example for placement of positions of calculation points is shown in Figure Figure An example for placement of positions of calculation points. 49

50 CHAPTER 4 MATERIAL AND METHODS Calculation height has been set at two metres above the ground. The calculated noise level L Aeq,24h contains reflection contribution from the building façade (The effect of reflection (- 3 db) was subtracted from the noise levels during data treatment). Noise exposure has been defined as the energy equivalent A-weighted sound pressure level over 24 hours (L Aeq,24h ). For each of the four calculation points per house, noise level L Aeq,24h has been calculated both as the total noise level and as the noise level from M3, the main road and the local road alone. As seen in an example in Figure 4.10: Herlev Hovedgade is the main road and Tuskhøjen and Havfruevej the local roads. In this analysis it has been decided to use the noise levels at the façade (without reflection from the façade) of each building facing M3, referring to the read calculation points marked number one in Figure A typical example for main road and local roads is shown in Figure 4.11 and Figure 4.12 respectively. Figure Typical example of other main road (normally with a large volume of traffic including heavy vehicles). 50

52 CHAPTER 5 RESULTS 5. RESULTS In this chapter, results of the investigation are given in seven groups, namely; study area study population annoyance from road traffic annoyance from road traffic noise noise abatement communication process change regarding noise environment The headings in this chapter are shown with the corresponding question numbers from the questionnaire, for example Age (Q37). As mentioned previously the pre-questionnaire can be seen in the appendices. All data analyses were carried out using the statistical program SPSS version 18. In this first analysis of the respondents answers to the questionnaires it has been decided to present the results using descriptive statistics in the form of frequency and percentage distribution. Verbal data was treated manually, by grouping the answers and taking their appearing frequency into account. 5.1 NOISE LEVELS IN THE STUDY AREAS Noise exposure levels were calculated as the energy equivalent A- weighted sound pressure level over 24 hours (L Aeq,24h ) (see Section 4.3 for calculation of noise exposure) for each area separately. In the following, the percentage of households exposed to different noise levels is presented for each of the six study areas. Both the total noise levels as well as the individual contributions from M3, other main roads and local roads are presented. In each figure, both the noise in the pre and post-situation are presented as outdoor noise levels. 52

53 CHAPTER 5 RESULTS AREA A Figure 5.1. Area A, calculated noise levels in db outside the house, (M: M3 alone). Figure 5.1. shows that the noise from M3 is reduced in area A after the widening of the motorway and establishment of noise barriers etc. At the outset, 7% of the dwellings were exposed to more than 60 db and in the post-situation this does not apply to any dwellings. Before the re-construction of the M3, 48% were between 55 and 60 db. This is reduced to 12%. In the aftersituation 82% of the dwellings are under 55 db. The noise exposure from other main roads in area A is shown in Figure 5.2. The contribution from other main roads is nearly the same in the before and after-situation. Around 90% of the dwellings are exposed to rather low noise levels under 45 db from these other main roads, so they only have a marginal influence on the general noise levels in the area. 53

54 CHAPTER 5 RESULTS Figure 5.2. Area A, calculated noise levels in db outside the house, (O: Other main roads alone). Figure 5.3. Area A, calculated noise levels db outside the house, (L: Local street alone). 54

55 CHAPTER 5 RESULTS In Figure 5.3, the noise exposure from local roads in the area is presented. Also here there is only a marginal difference between the before and the aftersituation. However, the local roads have a larger influence on the noise in the area than the other main roads. Comparing the three figures for M3, other main roads and local roads, it can be clearly be seen that M3 is the far the most important source to noise exposure in area A. Finally, the total noise exposure, predicted as the sum of the noise from the three road types can be seen in Figure 5.4 where the contribution from the M3 has by far the largest impact. There is a significant reduction in the total noise exposure in the after-situation. No dwellings are exposed to 60 db or more. 63% were previously exposed to 55 to 60 db; this is reduced to 47%. At the same time, a large number of dwellings end in the lower noise interval 50 to 55 db before it was 28% and this increases to 46%. Figure 5.4. Area A, calculated noise levels in db outside the house, (T: Total). 55

56 CHAPTER 5 RESULTS AREA B The noise exposure in area B is presented in the four figures below which show that the main noise source in area B also is M3 and the general situation is very similar to area A. Figure 5.5. Area B, calculated noise levels in db outside the house, (M: M3 alone). Figure 5.6. Area B, calculated noise levels in db outside the house, (O: Other main roads alone). 56

64 CHAPTER 5 RESULTS AREA F The noise in area F in the before situation can be seen in the four figures below. Figure Area F, calculated noise levels in db outside the house, (M: M3 alone). Figure Area F, calculated noise levels in db outside the house, (O: Other main roads alone). 64

65 CHAPTER 5 RESULTS Figure Area F, calculated noise levels in db outside the house, (L: Local street alone). Figure Area F, calculated noise levels in db outside the house, (T: Total). 65

66 CHAPTER 5 RESULTS Area F is situated at the eastern side of the motorway and there is a 280 m wide green recreational area in between. As for the other five areas also in area F, M3 is the main contributor to noise. Predictions for the after-situation have not been made as area F was excluded in the post-study. However, the noise levels in area F are significantly lower than in the other five areas. Nearly all dwellings are exposed to less than 55 db in the before-situation. The reason for that could be the green area between the motorway and the dwellings TOTAL NOISE IN ALL SIX AREAS In the four figures below, the noise is presented for all six areas. In the following Sections 5.2 to 5.7, the results of the two questionnaires are presented as totals for all six areas. Therefore, the figures below represent the noise exposure for all the respondents in the before and after-situations. Figure All six areas, calculated noise levels in db outside the house, (M: M3 alone). 66

67 CHAPTER 5 RESULTS Figure All six areas, calculated noise levels in db outside the house, (O: Other main roads alone). Figure All six areas, calculated noise levels in db outside the house, (L: Local street alone). 67

68 CHAPTER 5 RESULTS Figure All six areas, calculated noise levels in db outside the house, (T: Total). Figure 5.28 shows the total noise exposure on all the dwellings in the six areas. In the after-situation, no dwellings are over 60 db. 22% are between 55 and 60 db, but this is a significant reduction from the 45% in the beforesituation. Around 50% of all dwellings were under 55dB in the before-situation and this has increased to around 78% in the after-situation after the widening of the ring motorway. 5.2 STUDY POPULATION This section covers information about the study population before and after the extension of M3. Not all respondents have answered all the questions. Therefore, the total number of respondents varies somewhat from question to question. In the pre-study 848, in the post- study 636 questionnaires were received AGE (Q37) In question 37, the respondents were asked to state in which year they were born. The answers were converted to their age based on the year when the questionnaires were sent. The survey only included persons above the age of 18 years. The results are shown in Table 5.1 and Figure

69 CHAPTER 5 RESULTS Age Frequency Percentage [%] Before After Before After Total number of respondents Table 5.1. Responses to the question What year were you born? (Converted to age). Figure Responses to the question What year were you born? (Converted to age). 69

70 CHAPTER 5 RESULTS The percentage of people at the age of years decreased, while the percentage of people at the age of and slightly increased during the period of This can be interpreted that the population got slightly older along M3 during the period between pre and post-study. The age group of has the highest percentage by app 25%, while age group of has the lowest percentage by 3-5%, which can be explained by income differences between the groups. Increase in house prices makes it difficult for younger age groups to be able to afford to live in a house GENDER (Q38) In question 38, the respondents were asked to state their gender. The results are shown in Table 5.2 and Figure Frequency Percentage [%] Before After Before After Female Male Total number of respondents Table 5.2. Responses to the question What is your gender?.

71 CHAPTER 5 RESULTS As can be seen from the above table and figure, according to the collected responses there is a 7% increase of female responding population and vice verse on the male population between 2003 and INCOME (Q40) In question 40, the respondents were asked to state what their monthly household income is before tax. The results are shown in Table 5.3 and Figure respondents from the pre-study, 50 respondents from the post-study refused to answer this question, mainly because they found the question objectionable on the basis that it is too personal and some of them stated that they could not see any relation between their income and how much they are annoyed from the traffic noise. Since there was a high number of respondents who refused to answer, a new response category as refuse to answer was added to the table and the figure. Frequency Percentage [%] Before After Before After > Refused to answer Total number of respondents Table 5.3.

73 CHAPTER 5 RESULTS SENSITIVITY TO NOISE (Q41) In question 41, the respondents were asked to state how sensitive they are to noise. The results are shown in Table 5.4 and Figure Frequency Percentage [%] Before After Before After Very insensitive Relatively insensitive Normal Relatively sensitive Very sensitive Total number of respondents Table 5.4. Responses to the question How sensitive are you to noise?. Figure Responses to the question How sensitive are you to noise?. 73

74 CHAPTER 5 RESULTS From the figure it can clearly be seen that there is almost no difference between the noise sensitivity of the pre and post-study population. And in both situations, more than 70% of the respondents describe themselves as neither sensitive nor insensitive to noise, while only 3% of the same population describe themselves as very sensitive NUMBER OF PEOPLE PERMANENTLY LIVING IN THE RESIDENCE (Q43) In question 43, the respondents were asked to state how many people permanently live in their residence. The results are shown in Table 5.5 and Figure Frequency Percentage [%] Before After Before After More than Total number of respondents Table 5.5. Responses to the question How many people permanently live in your residence?. 74

75 CHAPTER 5 RESULTS Figure Responses to the question How many people permanently live in your residence?. As can be seen from the above figure, in general two people, living in a residence is almost twice as common as four people in their residence, which is the second most stated category. There is almost no difference between pre and post-study population regarding to how many people permanently live in their residence. 75

76 CHAPTER 5 RESULTS CHILDREN IN THE RESIDENCE (Q39) In question 39, the respondents were asked to state whether or not there are children at the age of 10 or younger in their residence. The results are shown in Table 5.6 and Figure Frequency Percentage [%] Before After Before After No Yes Total number of respondents Table 5.6. Responses to the question Are there any children at the age of 10 or younger in your residence? Figure Responses to the question Are there any children at the age of 10 or younger in your residence?.

78 CHAPTER 5 RESULTS The respondents are living in single family in one - two floor detached houses or row houses. There is nearly no difference between the before and the after situation OWNERSHIP OF THE RESIDENCE (Q19) In question 19, the respondents were asked to state who owns their residence. The results are shown in Table 5.8 and Figure Frequency Percentage [%] Before After Before After Privately owned Multi-ownership scheme Rental Other Total number of respondents Table 5.8. Responses to the question Who owns your residence? Figure Responses to the question Who owns your residence?. Approximately 90% of the residences are privately owned, while around 10% are rented. The situation is almost similar in the pre-and post study period. 78

79 CHAPTER 5 RESULTS YEARS IN PRESENT HOME (Q42) In question 42, the respondents were asked to state how long they have been living in their residence.

80 CHAPTER 5 RESULTS More than 60% of the survey population has been leaving in their residence more than 10 years. There is a slight increase in the percentage of people living in their homes for more than 10 years in the post-study. 0-2 years and a large part of the 3-6 years group did not participated in the pre-study, since there is six years in between pre- and post studies. More then 70% of the population have received both pre- and post questionnaires PLANS ABOUT MOVING (Q44, Q45) In question 44, the respondents were asked to state whether they are planning to move to another residence within the next few years. The results are shown in Table 5.10 and Figure Frequency Percentage [%] Before After Before After No Yes Don't know Total number of respondents Table Responses to the question Are you planning to move to another residence in the coming few years? Figure Responses to the question Are you planning to move to another residence in the coming few years?. 80

81 CHAPTER 5 RESULTS More than 70% of the respondents are not planning to move from their houses. There is app 3% increase at the post-studies. There is no change in the percentages of respondents who are planning to move. And there is a slightly decrease in the percentage of respondents who do not know. In question 45, the respondents were asked to state what the most important reason is, if they are planning to move. This corresponds to 10% of the respondents who answered in the previous question that they are planning to move. The respondents were allowed to put more than one mark in the response categories. The results are shown in Table 5.11 and Figure Frequency Percentage [%] Before After Before After Want to have another house condition (size, ownership) Want to live closer to work Traffic noise Vibration from road traffic Dust, smell from road traffic Unsafe to go out because of road traffic Want to live in an other neighbourhood Want better outdoor surroundings Want to live in a neighbourhood which has better institutions Want to live in a neighbourhood which has better free time offers Others Total number of respondents Table Responses to the question If you are planning to move, what is the most important reason?. 81

82 CHAPTER 5 RESULTS Figure Responses to the question If you are planning to move, what is the most important reason?. Traffic noise was the main reason (23%) for people to have plans to move in the pre- study and this decreased to 14% in the post-study. Another road traffic related response category dust/smell because of road traffic also decreased after the extension of M PARTICIPATION IN THE PRE-QUESTIONNAIRE (Q46) In question 46, the respondents were asked to state whether they had participated in the previous questionnaire investigation regarding noise before the widening of Motorway 3. The results are shown in Table 5.12 and Figure Frequency Percentage [%] Before After Before After No Yes Don't know Total number of respondents Table Responses to the question Did you participate to the previous questionnaire investigation regarding noise before the widening of Motorway (M3)?. 82

83 CHAPTER 5 RESULTS Figure Responses to the question Did you participate in the previous questionnaire investigation regarding noise before the widening of Motorway (M3)?. 38% of the respondents stated that they participated in the pre-study, while 23% mentioned that they do not know. Probably, the real participation from the same residence is somewhere between the sum of these two values (38-60%) since the participation of another person living at the same address is included in do not know option. There is in most areas an ongoing process of people moving to new homes for different reasons. Therefore it cannot be expected that it was exactly the same population who lived in the six areas in the before and in the after-situation. In the survey, the answers from all the respondents are included, both the people who participated in both the surveys and the ones who only participated in either the before or the aftersurvey. The description of the respondents in the before and after-survey can be summarized as the following: Everybody lives in a villa or a row house. 90% owns their own dwelling. Over 60% have lived in their dwelling for more than 10 years. 41% of the households have two inhabitants and 22% four inhabitants. In the post-study the respondents have lived longer in their dwelling. 83

84 CHAPTER 5 RESULTS 70% of the respondents have a normal sensitivity to noise. More people under 40 have participated in the pre-study. More people over 40 have participated in the post-study. The percentage of female respondents has increased from 41% to 49% in the post-study Approximately 70% of the respondents do not have children at the age of 10 or younger. In the post-study the respondents have somewhat higher income. 38% of the respondents participated in both the pre- and post-study. Both in the pre and post-study 10% have plans to move. In the pre-study 23% give noise as a reason for planning to move. This has decreased to 14% in the post-study. 5.3 ANNOYANCE FROM ROAD TRAFFIC (Q1) In question 1, the respondents were asked to state when they are at home, in which way are they annoyed by road traffic, where they live. The respondents were allowed to put more than one mark in the response categories. The results are shown in Table 5.13 and Figure In Figure 5.42 these results are shown for each of the six areas.

85 CHAPTER 5 RESULTS Figure Responses to the question Thinking about the last 12 months when you are at home, in which way are you annoyed by road traffic, where you live? (Total). As can be seen from figure 5.41 there is a significant decrease in the percentage of respondents who are annoyed by noise - from 83% to 68%. Increase in no annoyance from traffic in the post-study is in agreement with the results from question 45 (what the most important reason is if you are planning to move) where noise is a less important reason to plan to move in the poststudy. In the post study 20% did not experience any annoyance from road traffic. This was an improvement since it was 10% in the pre-study. 85

90 CHAPTER 5 RESULTS The percentage of very and extremely annoyed persons decreases from 37 % in the pre-study to 16 % in the post-study. The percentage of moderately annoyed is nearly constant with 30 % and 27 % respectively in the pre and poststudy. Finally the percentage of slightly or not annoyed increases from 33 % to 57 % from the pre to the post-study. As a total this is a remarkable reduction of the noise annoyance in the survey areas around M3 for the new situation after the extension of M INSIDE THE HOUSE (Q3, Q4, Q5) In question 3 the respondents were asked how much noise from road traffic annoy or disturb them when they are indoors in their home with closed windows. The respondents were asked to put mark on only one response category. Responses covering for all six areas are shown in Table 5.15 and Figure Frequency Percentage [%] Before After Before After 0=Not at all =Extremely Total number of respondents Table Responses to the question Thinking about the last 12 months, how much does noise from road traffic annoy or disturb you when you are indoors in your home with closed windows?. 90

Figure 5.44 shows an increase in the not at all annoyed response category from 23% to 36% indoors with closed windows after the extension of M3. At the same time there is an increase in all the annoyance categories from 2 to 10 (extremely annoyed). In question 4 the respondents were asked how much noise from road traffic annoys or disturbs them when they are indoors in their home with open windows. The respondents were asked to mark only one response category. Responses covering for all six areas are shown in Table 5.16 and Figure

93 CHAPTER 5 RESULTS When comparing the results from Figure 5.44 and 5.45, it can be seen that the annoyance increases markedly for the indoor situation when the windows are open compared to the situation with closed windows. In question 5, the respondents were asked how noise from road traffic annoys or disturbs them inside their home. The respondents were allowed to put more than one mark in the response categories. Responses covering all six areas are shown in Table 5.17 and Figure Frequency Percentage [%] Before After Before After Disturbs conversation Disturbs phone talk Disturbs listening radio/watching TV Disturbs reading/working Open windows less normally Use rooms differently than intended Difficulties in falling asleep Wake up at night Do not sleep with open windows Use earplugs when sleeping Use sleeping pills Other Total number of respondents Table Responses to the question Thinking about the last 12 months, how does noise from road traffic annoy or disturb you inside your home?. 93

94 CHAPTER 5 RESULTS Figure Responses to the question Thinking about the last 12 months, how does noise from road traffic annoy or disturb you inside your home?. As can be seen in Figure 5.25, there is a reduction of the reported annoyance and disturbance in the post-study. In the pre-study, 38% reported that they opened the windows less than normal; this has decreased to 28% in the poststudy. In the questions on sleeping quality, there is a remarkable improvement. In the pre study 14% reported difficulties falling asleep or being woken up during night time. This has decreased to 6% and 7% in the post-study. 94

95 CHAPTER 5 RESULTS OUTSIDE THE HOUSE (Q6, Q7) In question 6, the respondents were asked how much road traffic noise annoy or disturb them, when they are out in the garden, on the terrace or balcony. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.18 and Figure Frequency Percentage [%] Before After Before After 0=Not at all =Extremely Total number of respondents Table Responses to the question Thinking about the last 12 months, how much does road traffic noise annoy or disturb you, when you are out in the garden, on the terrace or balcony?. 95

In the post-study, there is a remarkable reduction in the respondents reporting high levels of annoyance (rating 8 to 10). In question 7, the respondents were asked how road traffic noise annoys or disturbs them when they are out in the garden, on their terrace or balcony. The respondents were allowed to put more than one mark in the response categories. Responses covering all six areas are shown in Table 5.19 and Figure

98 CHAPTER 5 RESULTS Figure 5.48 shows the reported annoyance when being outdoors. For all situations, there can be observed a decrease in the post-study. The percentage indicating annoyance during conversations is reduced from 36% to 20%. The percentage indicating annoyance while reading outdoors, decreases from 42% to 29%. Finally, the percentage annoyed while using the telephone is reduced form 19% to 12% 5.5 NOISE ABATEMENT WHAT SHOULD BE DONE TO REDUCE THE NOISE (Q15) In question 15, the respondents were asked what they think should be done to reduce noise annoyance from road traffic, where they live. The respondents were allowed to mark more than one response category. Responses covering all six areas are shown in Table 5.20 and Figure Frequency Percentage [%] Before After Before After Nothing Noise reducing windows Noise barriers Noise reducing road surface Less noisy car tyres Number of passenger cars reduced Number of lorries reduced Driving speed reduced Other Total number of respondents Table Responses to the question What do you think should be done to reduce annoyance from road traffic noise where you live? 98

99 CHAPTER 5 RESULTS Figure Responses to the question What do you think should be done to reduce annoyance from road traffic noise where you live?. As can be seen from Figure 5.49, in the pre-study 13% answered that nothing should be done to reduce the noise. This increased to 25% in the post-study. In the pre study around 60% of the respondents answered that noise barriers and noise reducing road surfaces should be used. Both tools to reduce noise were used in the project of widening the M3. In the post-study only 16% suggest noise barriers and 40% noise reducing road surfaces. In total, 89 written responses were given to the category other. Respondents recommended solutions such as reducing speed limit along the motorway, having continuous and intensive speed checks, building speed bumps along local roads, creating intensive vegetation along the motorway, reducing speed limit from 110 km/h to 90 km/h on the motorway, driving in electric cars, building higher noise barriers, increasing vegetation on the back side of noise barriers etc. Some of the answers covered more specific local situations such as stopping the neighbour s son driving on a moped or changing traffic direction along a specific road, while a few suggested more radical solutions such as closing down the motorway or building a tunnel instead WHAT HAVE THE RESPONDENTS DONE TO REDUCE NOISE (Q14) In question 14, the respondents are asked whether they have done anything where they live, to reduce noise annoyance from road traffic. The respondents were allowed to put a mark in more than one response category. Responses covering all six areas are shown in Table 5.21 and Figure

Figure Responses to the question Have you yourself done anything where you live to reduce noise annoyance from road traffic?. 100

101 CHAPTER 5 RESULTS Response distribution shows that both in the pre and the post-study, a large majority of the respondents (approx. 70%) did nothing to reduce noise where they live. Installing noise reducing windows is the second most common answer. The increase in the installation of noise reducing windows after the widening of M3 may partly be explained by the Danish Road Directorate s offer to subsidize sound insulation of building façades. In total, 38 written responses were given to the category other in question 14. The responses indicated that respondents also choose other solutions such as, planting higher trees, building up screens around their terrace, covering the terrace area completely etc. The other responses in that category are mostly repetition of already existing categories like installing noise reducing windows, to contact authorities and choose another room as a living/ sleeping room WHO SHOULD PAY FOR NOISE REDUCTIONS (Q17) In question 17, the respondents are asked who do they think should pay to reduce annoyance from noise, in their home. The respondents were allowed to put several marks in the response categories. Responses covering for all six areas are shown in Table 5.22 and Figure Frequency Percentage [%] Before After Before After No one Vehicle Drivers I / We House owners association etc Local authority/government EU Others Total number of respondents Table Responses to the question In your opinion, who do you think should pay to reduce annoyance from noise?. 101

102 CHAPTER 5 RESULTS Figure Responses to the question In your opinion, who do you think should pay to reduce annoyance from noise, here?. As seen from the figure, a large majority of the respondents see it as the responsibility of the authorities to reduce noise. In the pre-study, this was 81% and this was reduced to 72% in the post-study. Only 6 to 8% reply that they should pay themselves. The category none increases from 7% to 13% in the post-study. In total, 31 written responses were given to the category other in question 14. The responses cover a large number of very different answers. Some are repetitions or variations of the categories already provided (e.g. municipality, Danish Road Directorate, lorry drivers, motorcyclist, car owners), some are concerned with specific local problems (e.g. neighbouring gas station, post service, local business owners). There were also some unrelated responses that suggested solutions (e.g. to build more street bumps, to install noise reducing windows) instead of pointing out who should pay for it. 102

103 CHAPTER 5 RESULTS WILLINGNESS TO PAY (Q16) In question 16, the respondents are asked How much they are willing to pay in order to reduce traffic noise by one half where they live. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.23 and Figure Frequency Percentage [%] Before After Before After Nothing Up to 100 DKK per month Up to 250 DKK per month Up to 500 DKK per month More than 500 DKK per month Don't know Total number of respondents Table Responses to the question How much are you willing to pay in order to reduce traffic noise by one half her, where you live?. Figure Responses to the question How much are you willing to pay in order to reduce traffic noise by one half her, where you live?. 103

104 CHAPTER 5 RESULTS As seen from the figure, most of the respondents are not eager to pay at all (54% to 58%). This response shows agreement with question 17, where they see it as the responsibility of the authorities to reduce noise. But there is a certain willingness to pay (23% to 24%). There are 23% who in the pre-study do not know and this decrease to 18% in the post-study. 5.6 COMMUNICATION PROCESS PARTICIPATION IN THE PROCESS / DISCUSSIONS (Q34) In question 34, the respondents are asked whether they participated in the process/discussion about the rebuilding. The respondents were allowed to put more than one mark in the response categories. Responses covering all six areas are shown in Table 5.24 and Figure Frequency Percentage [%] Before After Before After I have participated at the residents meeting I have written letter/ reader letter to DRD I have participated at the house owners associations or similar group meeting I didn't want to participate I didn't get possibility to participate I have moved to the area after rebuilding has started Other Total number of respondents Table Responses to the question Did you participate in the process/discussion about the rebuilding?. 104

105 CHAPTER 5 RESULTS Figure Responses to the question Did you participate in the process/discussion about the rebuilding?. 29% of the respondents have actively participated in the process/discussion about the rebuilding of M3, while 40% did not wish to do so. 12% moved to the area after the rebuilding of M3 started. 18% of the respondents claimed they did not get the possibility to participate EXPERIENCE WITH THE COMMUNICATION PROCESS WITH DANISH ROAD DIRECTORATE AND OTHER ACTORS (Q33, Q35, Q36) In question 33, the respondents are asked how they experienced the way the Danish Road Directorate communicates with you as resident in connection with the widening of M3. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.25 and Figure

Figure Responses to the question How do you experience the way the Danish Road Directorate communicates with you as resident in connection with the widening of Motorway 3?. 59% of the respondents found the way the Danish Road Directorate communicates with them as resident in connection with the widening of M3 satisfying or very satisfying. The percentage of respondents who found the communication less satisfying is only 8%. 19% replied that there has not been any communication and 15% answer that they do not know. 106

107 CHAPTER 5 RESULTS In question 35, the respondents are asked whether their opinions or complaints been taken seriously by the Danish Road Directorate. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.26 and Figure Frequency Percentage [%] Before After Before After Yes Partly No Don't know Total number of respondents Table Responses to the question Have your opinions or complaints been taken seriously by the Danish Road Directorate?. Figure Responses to the question Have your opinions or complaints been taken seriously by the Danish Road Directorate?. 160 respondents did not give an answer to this question. The main reason is that there has been a lack of response categories which should cover people who did not state an opinion or complain. Most of this group ended up putting mark on response category of don t know. 107

108 CHAPTER 5 RESULTS In question 36, the respondents are asked whether the Danish Road Directorate and the involved contractors have been thoughtful to them /residents living along the Motorway 3 during the construction period in order to limit annoyance from noise, dust, smell etc. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.27 and Figure Frequency Percentage [%] Before After Before After Very thoughtful Reasonable thoughtful Little thoughtful Not thoughtful 30 5 Don't know Total number of respondents Table Responses to the question Has the Danish Road Directorate and the involved contractors been thoughtful to residents living along the way (Motorway 3) during the construction period in order to limit annoyance from noise, dust, smell etc? Figure Responses to the question Have the Danish Road Directorate and the involved contractors been thoughtful to residents living along the way (Motorway 3) during the construction period in order to limit annoyance from noise, dust, smell etc? 108

109 CHAPTER 5 RESULTS Most respondents (58%) state that they do not know whether the Danish Road Directorate and the involved contractors have been thoughtful to residents living along Motorway 3 during the construction period.the respondents are living at different distances form the construction site from being close neighbours to living 800 m away. It is presumably people living at larger distances who answer that they do not know. The remaining 42% of the respondents have an opinion about this and here 33% answer in the very or moderately thoughtful categories. 5% answer little thoughtful and only 5% answers not thoughtful. 5.7 CHANGE REGARDING NOISE ENVIRONMENT (Q8, Q9, Q10, Q11, Q12, Q13) In question 8, the respondents are asked whether they think the traffic noise where they live, has changed in the last two to three years. The respondents were asked to put a mark in only one response category. Responses covering all six areas are shown in Table 5.28 and Figure Frequency Percentage [%] Before After Before After No, it is more or less unchanged Yes, it is a little lower Yes, it has become somewhat stronger Other Total number of respondents Table Responses to the question Do you think the traffic noise here where you live, has changed in the last two to three years?. 109

When the respondents were asked if the noise had changed during the last 2 to 3 years 27% in the post-study answered that the noise has been reduced, and 44% think it is more or less unchanged. But also in the post-study 22% think the noise has increased. This is an improvement from the pre-study, where 58% stated that the noise had increased during the latest 2 to 3 years. In question 9 the respondents are asked from which roads they hear road traffic noise when they are at home. The respondents were allowed to put marks in more than one response category. Responses covering all six areas are shown in Table 5.29 and Figure

Figure Responses to the question From which roads do you hear road traffic noise when you are at home? M3 is the main noise source in the pre-study. 88 % can hear M3 and that is reduced to 80% in the post-study, indicating a reduction in the noise from M3 (see Figure 5.37). There is a slight increase in respondents who in the postsituation can hear noise from other main roads or local roads. 111

112 CHAPTER 5 RESULTS In the following questions about annoyance perceived separately from the three road types are presented: M3 Other main roads Local roads In question 10, the respondents are asked how much road traffic noise from the Motorway 3 annoys or disturbs them, when they are at home. The respondents were asked to put only one mark in the response categories. Responses covering all six areas are shown in Table 5.30 and Figure Frequency Percentage [%] Before After Before After Not at all Slightly Moderately Very Extremely Total number of respondents Table Responses to the question Thinking about the last 12 months, when you are at home, how much does road traffic noise from the Motorway 3 annoy or disturb you?

113 CHAPTER 5 RESULTS Figure Responses to the question Thinking about the last 12 months, when you are at home, how much does road traffic noise from the Motorway 3 annoy or disturb you? (The Motorway 3 not the Ring Road). Figure 5.38 shows the results of annoyance from M3. The results are nearly identical to the results when the respondents were generally asked about the noise annoyance in the area as shown in Figure 5.21, not specifying specific roads as the source of noise. This illustrates that M3 is the main source to road traffic noise in the areas. It can be seen that in the post-situation the percentage that are very and extremely annoyed decreases from 41% to 15%. At the same time, the percentage of not or slightly annoyed increases from 29 to 56%, whereas the percentage of moderately annoyed respondents is rather constant around 30% to 29% both in the pre and the post-study. This indicates a clear and significant reduction of the noise annoyance from M3 after the reconstruction of the road and instalment of noise barriers and noise reducing pavements. In question 11, the respondents are asked how much road traffic noise from other major through roads annoys or disturbs them, when they are at home. The respondents were asked to put only one mark in response category. Responses covering all six areas are shown in Table 5.31 and Figure

The level of annoyance is quite similar in the pre and post-study. Very much the same results can be seen for local roads where up to 90% are not at all or slightly annoyed (see Figure 5.40). 114

115 CHAPTER 5 RESULTS In question 12, the respondents are asked how much road traffic noise from local residential roads annoy or disturb them, when they are at home. The respondents were asked to put only one mark in response category.

116 CHAPTER 5 RESULTS In question 13, the respondents are asked whether there are other annoying or disturbing noise sources other than road traffic in the area. The respondents were allowed to put more than one mark on response categories. Responses covering for all six areas are shown in Table 5.33 and Figure Frequency Percentage [%] Before After Before After No Yes, railways Yes, airplanes Yes, business (e.g. restaurant, shop, workshop) Yes, public institutions, schools Yes, neighbours Yes, others Total number of respondents Table 5.33 Responses to the question Thinking about the last 12 months, are there other annoying or disturbing noise sources other than road traffic in the area?. Figure Responses to the question Thinking about the last 12 months, are there other annoying or disturbing noise sources other than road traffic in the area? 116

117 CHAPTER 5 RESULTS Figure 5.62 shows that road noise is the primary source to noise annoyance as around 60% of the respondents answer no to the question if there are other annoying or disturbing noise sources other than road traffic in the area. Around 20% also mention noise from airplanes. There is no significant difference between the pre and post-study. 117

118 CHAPTER 6 CONCLUTION 6. CONCLUSION Noise exposure levels were calculated as the energy equivalent A- weighted sound pressure level over 24 hours (L Aeq,24h ) for each survey area separately. Results shows that in all survey areas the main source to higher noise levels in the before situation is M3. The noise exposure from other main roads and local roads is remarkable lower. Therefore M3 is the main contributor to the total noise levels. In the after situation the noise from M3 is reduced and this also reduces the total noise exposure. In the after situation no households are exposed to more than 60 db; in the before situation it was 5%. In the after situation no dwellings are over 60 db. 22% are between 55 and 60 db but it is a significant reduction from the 45% in the before situation. Around 50% of all dwellings were under 55 db in the before situation and this has increased to around 78% in the after situation after the widening of the ring motorway. The description of the respondents in the pre and the post-studies can be summarized as the following: Everybody lives in a villa or a row house. 90% owns their devilling. Over 60% have lived in their dwelling for more than 10 years. 41% of the households have two inhabitants and 22% four inhabitants. In the post-study the respondents have lived longer in their dwelling. 70% of the respondents have a normal sensitivity to noise. More people under 40 have participated in the pre-study. More people over 40 have participated in the post-study. The percentage of female respondents is increased from 41% to 49% in the post-study. Approximately 70% of the respondents do not have children at the age of 10 or younger. In the post-study respondents have somewhat higher incomes. 38% of the respondents stated that they participated to the pre study while 23% mentioned that they don t know. Probably the real participation from the same residence is somewhere between the sum of these two values (38-60%) since the participation of another person living in the same address is included in don t know option. 118

119 CHAPTER 6 CONCLUTION Condensed it is the evaluation that the population of respondents in the pre and the post-study are relative alike and that it therefore is reasonable to compare the results from the two studies. The response rate was 71% in the pre-study and 65% in the post-study which must be considered quite fine is this type of public questioners. As a start the respondents got a general question on annoyance from road traffic. It is clear that noise is the dominant source to annoyance. Before the widening of the motorway 83% highlighted noise and after the reconstruction this was reduced to 68% and at the same time the percentage who do not experience any annoyance is increased form 10% to 20%. When the respondents were asked if the noise had changed during the last 2 to 3 years 27% in the post-study answered that the noise has been reduced, and 44% thinks it is more or les unchanged. In the post-study 22% thinks the noise has increased and this is an improvement from the pre-study where 58% stated that the noise had increased during the latest 2 to 3 years. The main result of the two studies is the changes in the generally perceived noise annoyance form road traffic in the whole area including noise from M3 as well as local roads and other main roads. The percentage of very and extremely annoyed respondents decreases from 37% in the pre-study to 16% in the post-study. The percentage of moderately annoyed is nearly constant with respectively 30% and 27%. Finally the percentage of slightly or not annoyed increases from 33% to 57% from the pre to the post-study. As a total this is a remarkable reduction of the perceived noise annoyance in the survey areas around M3 for the new situation after the extension of M3. The questionnaire shows that M3 is the main source noise annoyance. After extension process the effect of M3 decreases while other major roads and local roads became more obvious. There is a reduction of the reported annoyance and disturbance in the poststudy. In the pre-study 38% reported that they opened the windows less than normal; this has decreased to 28% in the post-study. In the questions on sleeping quality there is a remarkable improvement. In the pre-study 14% reported difficulties falling asleep or being woken up during night time. This has decreased to 6% and 7% in the post-study. For all activities related to being outside in the garden there is a decrease in the reported annoyance in the post-study. The percentage who indicates annoyance during conversations is reduced from 36% to 20%. The percentage who indicates annoyance while reading outside decreases from 42% to 29% and finally the percentage annoyed while using telephone is reduced form 19% to 12%. 119

120 CHAPTER 6 CONCLUTION More than 70% of the respondents are not planning to move from their houses. There is app 3% increase at the post studies. There is no change between the percentages of respondents who is planning to move. Traffic noise was the main reason (23%) for people to have plans to move in the pre study and it decreased to 14% in the post study. The respondents were asked what should be done to reduce the annoyance from road traffic noise. The percentage of respondents recommend that nothing should be done increased from 13% to 28%, the percentage of respondents who recommended to build noise barriers decreased from 61% to 28% while the percentage of respondents suggestion to use noise reducing noise pavements decreased from 61% to 40%. Response distribution shows that a large majority of the respondents (ca 70%) did nothing themselves to reduce noise where they live. Installing noise reducing windows is the second most pointed answer (15% to 20%). The increase on the installation of noise reducing windows after the widening of M3 may partly explained by the Danish Road Directorate s offer on subsidizing for sound insulation of building façade. A large majority of the respondents (more than 70%) see it as the responsibility of the authorities to reduce the noise. Most of the respondents are not eager to pay themselves at all to reduce noise. But there is a certain willingness to pay of 23% to 24%. There is 23% who in the pre-study don t know and that decreases to 18% in the post-study. 30% of the respondents have been actively participated to the process/discussion about the rebuilding of M3 while 40% didn t want to. 18% of the respondents claimed not getting the possibility for participation 58% of the respondents found the way the Danish Road Directorate communicates with them as resident in connection with the widening of Motorway 3 satisfying or very satisfying. The percentage of respondents who found the communication less satisfying is only 8%. 120

127 To Inhabitants on Road no Postal Code, Town Registration number Questionnaire regarding annoyance from road traffic noise Guldalderen Hedehusene Tlf Fax Vejdirektoratet.dk SE Giro EAN oktober 2009 Sagsbehandler Hans Bendtsen Dir. tlf [email protected] Ref.: «loebenr» Before the work started regarding the extension of Motorway 3, the Danish Road Directorate sent out a questionnaire regarding the annoyance from noise in different areas along the road. Now, that the extension has been completed in these areas, a new investigation is being carried out. Apart from showing in which way the extension has influenced the annoyance in the individual areas, it is also the purpose of the examination to update the basis which is being used to evaluate noise annoyance along roads. It is therefore of great importance to obtain as many answers as possible from all areas, even if the annoyance from noise is not so great. The questionnaire should be completed by a grown-up person over 18 years of age who is permanently resident at the address. If the address houses a business, shop, etc. without permanent residence, please put a tick on the following page and return this letter and the unanswered questionnaire in the enclosed envelope. In some questions you will find that we ask about the annoyance in two ways: Firstly you should choose the description of the annoyance which fits best. Then you should state on a scale from 0 to 10, how badly you are disturbed by the noise. If you feel no irritation, please choose 0. If you are extremely disturbed, please choose 10. If you feel your irritation lies between these two extremes, please place your tick somewhere in between, so it applies as best as possible. It is important that you answer both types of questions. The reason we put the questions in both ways is to be able to make a comparison with other international enquiries of a similar type. In some questions and at the end of the questionnaire there is a possibility to add some comments. Here we would ask you to write only within the space available, since your comments will be read by machine.

128 The questionnaire should be returned in the enclosed pre-paid envelope provided by the Danish Road Directorate. Please return the questionnaire no later than 6 November. It is important for the enquiry that we can identify where you are resident. Thus the questionnaires have been numbered. The Danish Road Directorate guarantees that all personal information will be treated in full confidence. If you have any further questions to the questionnaire or the enquiry, you are welcome to contact the undersigned by or phone. Yours sincerely and thank you for your assistance f/hans Bendtsen There is no permanent resident at this address: (Please return this letter and the questionnaire thank you).

155 Til Beboerne på Guldalderen Hedehusene Tlf Fax Vejdirektoratet.dk SE Giro EAN Spørgeskema om støjgener fra vejtrafik 29. oktober 2009 Sagsbehandler Hans Bendtsen Dir. tlf [email protected] Ref.: Før arbejdet med at udvide Motorring 3 begyndte, udsendte Vejdirektoratet et spørgeskema om støjgener i forskellige områder langs vejen. Nu, hvor udvidelsen er afsluttet ved disse områder, gentager vi undersøgelsen. Ud over at vise, hvordan udvidelsen har påvirket genen i de enkelte områder, har undersøgelsen til formål at opdatere det grundlag, der benyttes til at vurdere støjgener langs veje. Det er derfor vigtigt med en høj svarprocent også fra områder, hvor generne ikke er så store. Skemaet bedes besvaret af en voksen over 18 år med fast bopæl på adressen. Hvis der er tale om en virksomhed, butik eller lignende uden fast beboelse, bedes du blot sætte et kryds nederst på næste side og returnere dette brev og det blanke skema i den vedlagte kuvert. I nogle af spørgsmålene er der spurgt til gene på to måder: Først bedes du vælge den beskrivelse af genen, der passer bedst. Dernæst bedes du angive på en skala fra 0 til 10, hvor generet du er. Hvis du slet ikke er generet, vælger du 0. Hvis du er voldsomt generet, vælger du 10. Hvis du vurderer støjgenen til at ligge mellem disse to yderpunkter, sætter du kryds ved det tal mellem 0 og 10, der passer bedst. Det er vigtigt, at du besvarer begge typer spørgsmål. Der er spurgt på disse to måder for at kunne sammenligne resultaterne med andre internationale undersøgelser. Ved enkelte spørgsmål og til sidst i spørgeskemaet er der mulighed for at skrive kommentarer. Her beder vi dig om at holde dig inden for rammen, da kommentarerne ligesom svarene aflæses maskinelt. Spørgeskemaet returneres i den vedlagte svarkuvert til Vejdirektoratet portoen er betalt. Send venligst skemaet retur senest den 6. november.

156 Det er vigtigt for undersøgelsen, at svarene kan stedfæstes. Derfor er spørgeskemaerne nummereret. Vejdirektoratet garanterer, at alle personlige oplysninger behandles fortroligt. Har du spørgsmål til skemaet eller undersøgelsen, er du velkommen til at kontakte undertegnede pr. eller telefon.
