The Decision Support Tool for urban mobility services is a scientific and technical procedure, aiming to explore available urban mobility solutions for cities, through a variety of mobility data sources available. Policy makers can resourcefully use the integrated Toolset to investigate mobility scenarios in every city, in order to enhance environmental sustainability and social responsibility while simultaneously securing efficient budgeting allocation. The Decision Support Tool has been implemented under the European Project MOMENTUM, by Centre for Research & Technology Hellas Hellenic Institute of Transport (CERTH/HIT).
