In the context of the acatech project “Integrierte Stadtentwicklung und Mobilitäsplanung”, this report “Mobility transition and governance in EU Municipalities” examines what sustainable transition strategies are being developed by regions and municipalities in Europe and what results they achieve. Drawing on four cases considered as pioneers in promoting innovative forms of integrated transport and urban planning to achieve transformative change, it feeds into the work done at project level about what design and planning approaches can be transferred to other regions and municipalities, and into the provision of guidelines for interdisciplinary urban and mobility planning in the German federal context.
