1 IV INTERNATIONAL MEDIA FORUM ON THE PROTECTION OF NATURE PROTECTION OF NATURE, PROTECTION OF HEALTH Tools for a sustainable mobility to clash the traffic and pollution in the urban area: a critical review Carlo Carminucci Director Research Area of Isfort Villa Mondragone, October 2006

2 This presentation is divided into two sections 1. A short description of the characteristics of the demand for urban mobility, starting from data supplied by Audimob, Observatory on Italians Mobility Styles and Behaviors 2. A concise review of the policies and measures for a sustainable urban mobility, with a few examples of good practices

12 Second section POLICIES AND MEASURES FOR A SUSTAINABLE URBAN MOBILITY: A CONCISE REVIEW

13 A summary of policies and measures for a sustainable mobility in the urban area Policies 1. Fares and pricing 2. Management of the demand for urban mobility 3. Public transport 4. Not pollutant modes of transport 5. Land use and transport Measures Road pricing Park pricing Traffic calming Limitation of vehicle traffic Car-pooling Car-sharing Information Technology (ITS) Bus priority Tariff integration Infomobility Bicycle and pedestrian mobility Integrated planning between transport and land use

14 Concrete actions: road pricing Consolidate practices Singapore (1975) Middle towns in Norway: Bergen, Oslo, Trondheim (end of 80) London Stockholm Studies and Projects Middle towns in UK (Bristol, Edinburgh) Paris, Marseille Genoa, Rome, Milan (studies and experiments)

15 A successful case: London s congestion charge Introduced in 2003, after many years of studies and modeling simulations. The interested zone (only on weekdays) is delimited by the Inner Ring Road (22 sq. km.). Starting from February 2007, the area will be extended to the west of the city (a further 20 sq. km.). After merely a year, considerable results have already been attained: sizable reduction in car traffic (-39%), increase in public transport (+38%), decrease in bus waiting time (-30%), decrease in the number of accidents (-9%), and decrease in traffic emissions (-12%, nitrogen oxides and fine dusts). Unexpected negative effects: nearly 50% lower returns than expected owing to the extremely high reduction in the number of cars entering the city and the high number of cars that are exempted from the charge.

16 Concrete actions: car-sharing Car sharing replaces the ownership of a car with a system of car rental by a community of users (multi-owned cars for several users). Car sharing is considered an efficient alternative to the ownership of a car for users who cover less than 10,000 km a year. The introduction of the car-sharing services aims at: separating the use of a car from its ownership, and this applies in particular to that that share of motorists who does not drive the car on a regular basis for its journeys; minimizing vehicle traffic by stimulating the use of collective transport; reducing the needs for parking spaces in crowded urban areas, through a drop of the population motorization rates

17 Concrete actions: car sharing Starting from the 1980s, a growing recourse to car-sharing arrangements has been reported in a few central European countries (Germany, The Netherlands, and Switzerland) and, later on, in the United States and Canada. Considered as a whole, the three European countries rely on over 100 organizations and in excess of 100,000 users. In the United States, 17 car-sharing organizations involve nearly 76,500 members (in 2005) with a vehicle fleet of 1,200 cars. In recent years, a few interesting initiatives have also been developed in Austria, Denmark, France and Italy. The spread of the car-sharing service proceeded at the same rate as the development and spread of the technologies applied to the mobility sector: telecommunication systems to manage reservations and car-sharing services (web portals for communication among members and the operation headquarters), smart cards for access and financial management (invoicing system), satellite control of vehicles (GPS) and so on.

18 Concrete actions: supporting the use of bicycles The mobility of urban areas in Europe and particularly in Italy combines well with the bicycle mode of travel (short-distances, facility of access and parking, etc.). However, this potential is frustrated by the conflict between bikes and vehicle traffic. The promiscuity of the routes and, above all, the speed disparity between bikes and cars reduce to a considerable extent the safety conditions related to the weaker mode of transport. The situation is compounded by the poor quality of urban environments, often characterized by high levels of atmospheric and acoustic pollution. A few experiences: the Bike Offices, Calla-bike, Piedibus.

19 A final remark Time and money are scarce! Urban policies for a sustainable mobility should be: 1. diversified and integrated 2. focused on local pattern 3. effective (strategic level) 4. efficient (operative level)
