Global socio-economic and environmental megatrends are urging for a paradigm shift in mobility and transport. An action plan for the coherent implementation of innovative transport and mobility solutions in Europe is thus urgently needed and should be sustained by a wide range of societal stakeholders. The MOBILITY4EU project is working on developing such an action plan considering all modes of transport of passengers and freight. This contribution details the methodology and the results on trends, solutions and opportunities for cross-modal and cross-sector collaboration. The initiative towards a European Transport and Mobility Forum that continues the work beyond the project duration and works on complementing the action plan is introduced.
