The European Commission has outlined future transport research and innovation (R&I) priorities to decarbonise the European transport sector in its Strategic Transport Research and Innovation Agenda (STRIA) that includes seven roadmaps in seven priority areas that cut across transport modes. In order to support the implementation of STRIA, a Transport Research and Innovation Monitoring and Information System (TRIMIS) has been developed. This paper reviews the features and added value of TRIMIS as an integrated analytical support tool and platform that monitors transport R&I and provides feedback to policy and decision makers. TRIMIS is an open-access information and knowledge management system, and includes a database of transport projects and programmes, as well as an inventory of transport technologies and innovations. It goes beyond previously available tools by providing a holistic assessment of emerging technologies and R&I capacities in the transport sector in all seven priority areas, and by developing analytical tools on the European transport sector.
