The Dynaxibility4CE, as part of an experimental call from the Interreg Central Europe program, focuses on the priority of low-carbon mobility and air quality. It aims to increase the ability of public transport authorities to deal with new mobility trends. This will be achieved by developing strategies and tools for public (transport) authorities that strengthen the planning capacities of cities throughout the region of Central Europe. Thus, the project enables these authorities to become key actors for creating low-carbon and low-pollution mobility systems in their respective regions.
