Mobility in Potsdam

Since July 2017, the city of Potsdam has implemented a temporary traffic measure on the Zeppelinstrasse.

To understand how residents and commuters of Brandenburg’s capital perceive this measure, researchers at the IASS are conducting an anonymous questionnaire-based survey that aims to investigate the following:

• How do residents and commuters perceive their surrounding environment?

• How do residents and commuters rate the traffic measure?

• How does the traffic measure affect daily mobility decisions?

The survey is now closed and the project has been completed. We would like to thank everyone for taking part in the survey. The results in the form of a brochure can be found under the following link (available only in German):

Part I (main report) - Luftqualität, Mobilität und nachhaltige Städte

Part II (supplementary report) - Qualitative Inhaltsanalyse

Please note:

This anonymous online survey is supported by the Potsdam based initiative „Besser Mobil. Besser Leben.”. However, the survey was not contracted by the city and is therefore not the foundation of the decision-making process. The results will be shared with the city administration and the public.

More information regarding the traffic measure and the “Besser Mobil. Besser Leben.” initiative can be found below.

Peer-reviewed Publications

In addition to completing the above report, the survey work done in this project led to the publication of three separate peer-reviewed publications. These can be found here:

Climate change and air pollution: the connection between traffic intervention policies and public acceptance in a local context (07.2019)

Determinants of public acceptance for traffic-reducing policies to improve urban air quality (07.2019)

An assessment of perceptions of air quality surrounding the implementation of a traffic-reduction measure in a local urban environment (08.2018)


Urban mobility is a key issue to making cities more inclusive, safer, and more environmentally friendly. To ensure a sustainable future, local policy should, among other actions, aim to improve access to sustainable transport systems and enhance mobility opportunities, while simultaneously addressing critical environmental and health goals.

In order to assess whether these objectives are met, transport measures should be regularly evaluated from a social and environmental perspective.

The implementation of such measures raises many questions: How do interactions affect the quality of life of the residents? What are the inhabitants’ perceptions with respect to changes in the mobility network? Does the public accept these policies? Citizens' opinions towards and their acceptance of environmental policies are crucial to successful implementation.

Zeppelinstrasse Temporary Traffic Measure

In order to improve the mobility network in Potsdam, the number of lanes in the Zeppelinstraße will be reduced for six months. For drivers there will be one lane for each direction of traffic, as well as a turn lane. The additional space will be made available to buses and cyclists.

In order to understand how this measure is perceived by the citizens of Potsdam and the surrounding communities, the IASS is conducting a survey. The aim of the survey is to determine the acceptance and awareness of the traffic measure in connection with sustainability topics.

“Besser mobil. Besser leben.”

Potsdam, the capital of the state of Brandenburg, is on its way to a sustainable future. With the "Besser mobil. Besser leben." initiative, the administration has put conscious effort to the promotion of sustainable mobility and thereby a positive attitude towards life in the city. The initiative was kicked off with a Mobility Day event in 2015 and will continue for several years. Potsdam's citizens will remain informed about the core issues of sustainable mobility and alternatives to car-use in the dynamically developing state capital over the next few years.
