Quality of life and climate protection. Bremen and Stuttgart as model cities for the future
Applying visionary concepts, the cities of Bremen and Stuttgart could reduce car traffic by 40 percent as well as their climate-damaging emissions by 70 percent until 2050. Together with the persons responsible from the municipalities of Bremen and Stuttgart, the German Öko-Institut, an institute for applied ecology, analysed the environmental effects of those measures, which are planned from today till 2025 resp. 2030. Additionally, climate protection scenarios were expanded by adding further ideas for increasing the quality of life until 2050.
In its transport development plan the city of Bremen has defined a broad range of measures for the period until the year 2025, focusing the fields of local mobility, cycling, public transport, car sharing and public relations. The plan gives the frame for a 10 percent reduce of car traffic. At the same time, the modal shares of public transport, cycling - with currently 25% already quite high - and walking will increase. Until 2050 it is thinkable, that car use will decrease by 42 percent, while bicycle traffic will increase by 54 percent. That is shown by the Öko-Institut's analyses, which is based on the assumption, that for the future, the people of Bremen will drive their private cars less, using the expanded offers of public transport and cycling infrastructure or walking. Furthermore, price policies will have their effects and e-mobility will be used more intensely.
In Stuttgart, the municipal transport development concept and the majors action plan Sustainably mobile in Stuttgart include the expansion of public transportation, support for cycling, improvements in traffic education and traffic supervision, parking space management, the extension of e-mobility and the implementation of a 40 km/h speed limit on street slopes. Realizing those steps, motorized individual traffic can be reduced by presumably 12 percent until the year 2030, as the Öko-Institut's analyses show. At the same time, public transport will be used more intensely, providing about 25% of the traffic capacity. As it did for Bremen, the Öko-Institut has developed additional traffic measures for Stuttgarts planning until 2050: Cycling infrastructure extension, especially for pedelecs, an increased public transport use, the implementation of a regional road charge and a further increase in e-mobility. By implementing those as well as further measures, it should be possible to reduce car traffic by 42 percent until 2050 and to increase the traffic capacity of public transport up to 43 percent. Bicycle traffic can actually increase by 240 percent between 2010 and 2050.
