This article describes some research results towards sustainable mobility in German context at the example of Karlsruhe: While during the 1950’s and 60’s the vision of the car-oriented city shaped the cities’ appearance to large extend, in the 80’s and 90’s in the city of Karlsruhe the first fundamental change took place. The implementation of “public-transport”-vision prevented the further increase of car traffic. In the 2000’s and 2010’s, the vision of the “cycling city” led to a massive increase of cycling and a reduction of car traffic. However, climate adaptation requires a transformation of public space towards blue-green designs and the 15-min-city vision. This vision seems to be implemented since the 2020’s. But also, autonomous driving promises the solution of transport problems. The research project AutoRICH examined this promise using various scientific methods and found it to be false until autonomous vehicles are regulated to be used as sharing and pooling vehicles exclusively. Additionally, in a living lab the potential of e-bikes as a game-changer in mobility was examined and found to be quite promising: Since an extremely expensive transformation of car fleet and infrastructure to a digital system, it seems much more senseful to invest into climate adaptation in public space regarding space for cycling and walking. Finally, it more and more turns out that the boundary conditions in the living quarters are of great importance concerning mobility behaviour of the residents: Good local supply, easy access to bike, and public transport are crucial for future development.
