Regions, cities but also medium-sized towns are regularly confronted with the necessity to assess the impact of transport strategies, action plans or transport infrastructure measures. Within the Sustainable Urban Mobility Planning (SUMP) process e.g., municipalities are invited to build and jointly assess scenarios depicting the development of the transport system and mobility behaviour as part of the strategy development process.

Simulation tools and their underlying transport models play a crucial role to support these processes, both on micro and macro level.  However, output data of these models are usually not suited for a comprehensive sustainability assessment. It was thus the aim of the research project "MOTUS - Mobility Transformation: Understanding key factors for sustainable and resilient transport" to develop a suitable assessment tool for this application. Based on a profound literature analysis, relevant sustainability impacts have been identified and combined with an impact evaluation framework allowing for an indicator-based assessment of scenarios. Indicators have been adapted to the input and output data commonly available in transport models. 

The sustainability assessment approach has been tested with an agent-based transport simulation, built for the city of Bad Hersfeld in Hesse, Germany, with the aim to explore strategies to improve the overall sustainability of the transport system.
