German municipalities are facing an unprecedented challenge: the transformation of urban transportation towards sustainable, efficient, and equitable mobility. This task is not only a response to the pressing issues of anthropogenic climate change and emitted pollutants but also an opportunity to fundamentally improve the quality of life in urban areas. The publication Mobilitätswende and its website platform provide decision-makers, planners, and the interested public with a qualified overview of promising solutions and best practices that have already been implemented, tested, or have the potential to make a significant contribution to the mobility transition. At the same time, the platform offers everyone the opportunity to network with each other and contact project managers.
