Traffic Monitoring Report 2014

Summary SUMMARY Rural Traffic 1. The number of motor vehicles recorded crossing the County Screenline in 2014 was 3.8% higher than in 2013 and 8% greater than in 2004. 2. The A14 remains the busiest road in the county, with an average annual daily flow of over 86,000 vehicles between Dry Drayton and Cambridge. 3. The highest growth since 2002 on trunk roads within the County has occurred on the A428 (25%) which is related to the development of Cambourne. On the County s principal road network, the greatest growth in traffic over the past ten years has occurred on the A10 (26%). 4. Traffic density on Cambridgeshire s rural trunk A roads is almost twice the national average, and is 40% above average on other rural A roads. 5. The density of HGV traffic on Cambridgeshire s trunk A roads is almost three times the national average, and on non-trunk main roads it is 79% above the national average. Cambridge 6. In 2014, there were just over 200,000 motor vehicles entering and leaving Cambridge per 12-hour day (7am to 7pm). This represents an increase of 5% compared with 2013. Prior to this the long-term trend over the past 17 or 18 years was relatively flat. Given that the cordon surveys are one-day counts, it is unclear as to whether or not this is a change in the underlying trend. 7. At just under 60,000, per 12-hour day, the number of motor vehicles crossing the River Cam bridges within Cambridge was 1% less than in 2013 and 15% less than 10 years ago. 8. There were about 3.5 million Park and Ride journeys in 2014, representing a decrease of 5% compared with 2013. Other Urban Areas 9. The numbers of motor vehicles entering and leaving the nine market towns per 12-hour day in 2014 were: Huntingdon 75,068, Wisbech 64,818, St. Neots 54,170, St. Ives 48,229, Ely 42,642, March 35,116, Whittlesey 32,061, Ramsey 19,276 and Chatteris 18,997. Cycling 10. There was a 17% increase in cycle trips in 2014 compared with 2013. There has been significant growth of 55.6% from the 2004-05 average baseline. Cambridgeshire Guided Busway 11. During 2014 there were 3.6 million passenger journeys on the Cambridgeshire Guided Busway. 1

Introduction 1. INTRODUCTION Purpose of the Traffic Monitoring Report 1.1 The County Council, as Highway Authority, is responsible for all public roads within the county, except for the motorway and trunk road network, which is the responsibility of the Department for Transport, (DfT). In order to fulfil its functions, the County Council requires up to date information on vehicle flows, flow composition, vehicle occupancy and overall trends. This information is used:- to identify and justify transport schemes; to assist in the priority ranking of schemes ; for strategic planning; for development control purposes; in road maintenance assessments; in road safety investigations; in the environmental assessment of schemes; for the monitoring of targets; to provide a database of information. 1.2 This report examines traffic and travel trends for both rural and urban roads within the county. Where appropriate, trends are compared with national statistics. Variability in Traffic Counts 1.3 Much of the information in this report is based on twelve-hour manual traffic counts. 1.4 Due to the random nature of traffic flow, even if counted under identical conditions the number of vehicles recorded in these samples will fluctuate. The associated uncertainty reduces (in percentage terms) as the number of vehicles increases. 1.5 More serious, and much harder to quantify, is potential systematic variation due to differing circumstances when counts are carried out. Three examples are:- Roadworks, accidents or other incidents causing vehicle diversions; Changes in travel mode due to weather; Unusual events (e.g. sport or entertainment events) causing untypical traffic patterns. 1.6 Care is taken to minimise the potential for systematic variation, but, inevitably, there is no guarantee that it is completely eliminated. 1.7 Because of random and possible systematic variation, caution is needed when interpreting observed changes in traffic from one year to the next. 3

Rural Traffic 2. RURAL TRAFFIC Introduction 2.1 A programme of 12-hour manual classified traffic counts conducted at the same time each year, along two imaginary screenlines, determines traffic growth statistics for the rural areas of Cambridgeshire. These screenlines, illustrated in Figure 2.2, run north-south and east-west across the county, intersecting to the south of Chatteris. 2.2 The following tables illustrate figures for Cambridgeshire, together with the equivalent national statistics, which are published by the Department for Transport (DfT). 2.3 Additional information from automatic traffic counting equipment is summarised in Chapter Six. Traffic Growth Across County Screenline 2.4 The growth in all vehicle traffic crossing the rural county screenline is shown in Table 2.1 below. The number of motor vehicles recorded crossing the screenline in 2014 was 3.8% higher than in 2013, although as this is based on a one-day count the numbers do fluctuate from one year to the next. There has been an increase of 8% over the past ten years compared with 4% growth nationally.

On the county principal road network, the highest growth over the past ten years has occurred on the A10 (26%). 2.14 The A14 has the greatest volume of HGV traffic, followed by the A1(M). 20% of all traffic on the A14 at Swavesey is HGVs. 8

Cambridge City 3. CAMBRIDGE CITY Introduction 3.1 Traffic flows have been monitored comprehensively in Cambridge since 1978 using two screenlines. 3.2 The first screenline runs along the River Cam, with vehicles, pedestrians and cyclists crossing all bridges in the city centre being counted in the Spring of each year. 3.3 The second screenline is a radial cordon, with vehicles, pedestrians and cyclists on every entry and exit route counted in the Autumn. Eight sites are also monitored to count cyclists and pedestrians on paths between the radial routes. 3.4 Chapter Five contains a comparison of traffic and travel patterns in Cambridge and nine market towns. Additional information from automatic traffic counting equipment in the city is summarised in Chapter Six, and Chapter Seven includes further data on cycling. River Cam Screenline 3.5 Vehicles and pedestrians crossing the River Cam urban screenline in March 2014 are shown in Table 3.1. The figures include cycle and pedestrian traffic on the City s River Cam cycle and pedestrian bridges.

This represents an increase of 5% compared with 2013. Prior to this the long-term trend over the past 17 or 18 years was relatively flat. Given that the cordon surveys are one-day counts, it is unclear as to whether or not this is a change in the underlying trend.

Town Monitoring 4. TOWN MONITORING Introduction 4.1 The market town monitoring programme was extended in 2004 to include three more towns: Chatteris, Ramsey and Whittlesey. 4.2 For each town there is an outer cordon. The total number of vehicles crossing the cordon provides an estimate of traffic entering and leaving the town. 4.5 Results are presented for each town, and Chapter Five contains a summary and comparison between towns. St. Neots 4.6 The locations of the monitoring points are shown in Figure 4.1 and the results are summarised in Tables 4.1 and 4.2. 4.7 About 54,200 motor vehicles, 900 pedal cycles and 2,800 pedestrians enter and leave St. Neots between 7.00 am and 7.00 pm each day (two-way flows).

Continuous ATC data averaged over three years have been used at selected sites to produce Figures 6.3 to 6.6, which illustrate the variations that have occurred on particular motorway, trunk, county primary and urban primary roads. In these graphs October flow is taken as the base index of 100. Daily Variation 6.5 Traffic flows also vary throughout the week, and again different roads exhibit slightly different patterns. Daily flows were averaged over a year on the same road links used to calculate monthly variations. The weekly profiles are shown in Figures 6.7 to 6.10, where Wednesday flow is taken as the base index of 100. 38

Continuous Traffic Information Traffic Flow Conversion Factors 6.6 Manual classified counts are usually counted over 12 hours duration on any weekday except Fridays. Factors have been calculated for all permanent ATC installations, where data are available, to convert 12 hour Annual Average Weekday Flows (AAWF) to 16 hour AAWF, 24 hour AAWF and 24 hour Annual Average Daily Traffic (AADT) averaged over seven days. These conversion factors are recorded in Tables 6.4 to 6.7 below. Note: 16 hour AAWF is the average Monday to Friday flow throughout the year. 24 hour AAWF is the average Monday to Friday flow throughout the year. AADT Annual Average Daily Traffic is the average flow on an average day (Sunday to Saturday inclusive), throughout the year, and is expressed as a 24-hour flow.

Cycle Monitoring 7. CYCLE MONITORING 7.1 The numbers of cyclists using particular routes over the past ten years is shown in Table 5 in Appendix 2. 7.2 Automatic cycle counting loops have been installed at a number of sites in the County. Average daily flows are recorded in Table 7 in Appendix 2. The conversion of all pedal cycle counters to telemetry is now complete. This enables permanent data collection at all sites. Growth in Cycling 7.3 Cycling growth is measured by the overall increase across a number of automatic and manual count points located throughout Cambridgeshire, giving a large, robust sample. 7.4 There was a 17% increase in cycle trips in 2014 compared with 2013. Overall growth from the 2004-05 average baseline is 55.6%, which is better than the Council's target of 33.6%. 7.5 The River Cam bridge surveys undertaken in March are a major component of the index Table 7.1 Cambridgeshire Cycle Flows at Selected Locations Year Increase from 2004-05 average baseline 2011 33.2% 2012 35.8% 2013 32.8% 2014 55.6% Journey to Work by Pedal Cycle 7.6 Data from the 2011 national census shows that 30% of journeys to work by Cambridge residents are by pedal cycle. For Cambridgeshire as a whole the figure is 9.7%, which is much higher than the average 3% for England. 7.7 Data from the 2014 Cambridgeshire Travel for Work survey shows that 32% of journeys to work on weekdays were by pedal cycle, in 2013 the figure was 25%. In 2013 the average distance cycled to work was 3.6 miles. Further details can be accessed via the following link: http://www.tfw.org.uk/documents/survey/tfw%20&%20tp+%20overall %202014%20Survey%20Reportv2.pdf 7.8 The latest available data from the Sport England Active People survey, published by DfT in April 2014, shows that in the 12 months ending October 2013 21% of adults in Cambridgeshire cycled at least once a week. The corresponding figure for Cambridge is 49%, which is the highest in the country www.gov.uk/government/organisations/department-fortransport/series/walking-and-cycling-statistics 44

THE BUSWAY Introduction 8.1 The Busway opened on 7 th August 2011. This chapter contains some data about use of the Busway, including numbers of bus passengers, cyclists and pedestrians, as well as changes in traffic on surrounding roads. Passenger Journeys 8.2 During 2014 there were 3.59 million bus passenger journeys on the Busway. The upward trend is shown in Figure 8.1 below 4,000,000 3,500,000 3,000,000 2,500,000 2,000,000 1,500,000 1,000,000 500,000 0 Figure 8.1 Guided Busway Passenger Journeys 12-Month Rolling Total 12 months ending Cyclists and Pedestrians Using the Busway Maintenance Track 8.3 Table 8.1 below shows numbers of cyclists and pedestrians using the maintenance track beside the Busway per 12-hour day (between 7am and 7pm).

There were 11,000 cycle journeys (twoway) across the cordon per day between 7am and 7pm. 45

Busway Opened Traffic Monitoring Report 2014 The Busway Changes in Traffic on the A14 8.5 Data from Highways Agency automatic traffic counters on the A14 and other trunk roads are summarised in Table 8.2 below. Annual Average Weekday flows for 2014 are compared with the 12 months preceding the Busway opening (August 2010 July 2011) Table 8.2 24-hour Annual Average Weekday Traffic Flow (AAWF) on A14 and other Trunk Roads Aug 2010 to Jul 11 Change % 2014 A14 West of Huntingdon A14 Catworth Hill 43,830 41,928-4.3% A14 Junction 20 Ellington 46,063 44,056-4.4% A14 Huntingdon to Cambridge Junctions 23 to 24 - A14 Spittals to Godmanchester 75,405 76,156 1% A14 South of Dry Drayton jnc 94,778 93,304-1.6% A14 Cambridge Northern Bypass A14 Milton 63,265 64,147 1.4% A14 Quy 38,171 39,096 2.4% A14 Suffolk A14 Junction 55, Suffolk 26,375 28,818 9.3% A14 Trimley Heath, Suffolk 36,343 - - M11 M11 Junctions 10 to 11 53,907 55,286 2.6% M11 Junctions 11 to 12 69,269 70,111 1.2% A11 A11 Between A505 and A1301 29,547 29,424-0.4% Between A1307 and A11 A1304 38,844 39,080 0.6% A1 & A1(M) A1(M) Alconbury to Sawtry 70,360 - - A428 A428 Caxton to Cambourne 28,341 31,448 11% A428 Cambourne to Hardwick 31,082 34,221 10.1% 46

The Busway 8.6 In 2014 there was a reduction of 1.6% (just under 1500 vehicles per day) on the section of the A14 between Dry Drayton and Cambridge compared to between August 2010 and July 2011, which is a section of road that would be expected to see a decrease in traffic due to people using the Busway. This reduction is larger than on any of the other sections of road in Table 8.2 with the exception of the A14 west of the A1. 8.7 The decrease on the A14 west of the A1 is correlated with completion of the dualling of the A421 between Bedford and the M1. This occurred in Dec 2010 and completed the creation of a dual carriageway between the A1 and M1 via the Bedford bypass. Prior to Dec 2010 there were extensive roadworks and disruption on that section of the A421. 8.8 It would appear that the Busway has had an impact at Dry Drayton and the A421 at Catworth. 47

Definitions APPENDIX 1 DEFINITIONS General Traffic Flow The number of motor vehicles in a given period of time, expressed as a two-way total. 12 hour flow Traffic flow in the period between 7 am and 7 pm. This is the usual period observed for manual traffic surveys. 16 hour flow Traffic flow in the period 6 am to 10 pm 18 hour flow Traffic flow in the period 6 am to midnight; traffic surveys over this period are used for environmental and traffic noise studies. 24 hour flow Traffic flow over the entire 24-hour period. 12 hour AAWF Annual Average Weekday Flow (Monday to Thursday inclusive) throughout the year. This is usually based on counts carried out during the Spring and Autumn months. 16 hour AAWF The Annual Average Weekday Flow (Monday to Friday inclusive) throughout the year. 24 hour AAWF The Annual Average Weekday Flow (Monday to Friday inclusive), throughout the year. AADT ATC MCC Screenline Annual Average Daily Traffic is the average flow on an average day, i.e. Sunday to Saturday inclusive, throughout the year and is expressed as a 24-hour flow. Automatic Traffic Counters are battery powered wire loop detectors operating from permanent loops cut into the road. The loops create a magnetic field, which is disturbed when a vehicle passes over it. Manual Classified Count is a traffic count undertaken by manual observation, recorded and classified by vehicle type and time period. An imaginary line drawn across a transport corridor (often following a physical barrier such as a river or a railway line) used to determine net flows between the areas on either side. Note: It is generally accepted that the 24 hour Annual Average Daily Traffic flow is the same as (or very similar to) the 16 hour Annual Average Weekday Flow. 48
