Scenario Co-Design for Systemic Evaluation of Connected and Automated Mobility Setups

Connected and automated vehicles are today at various stages of development. Due to their transformative potential, both on the existing transport system and on urban spaces, it is essential to investigate their impacts from a systemic perspective. A multi-factor evaluation cannot be based only on experimental setups. Projections of up-scaled, operational connected and automated mobility (CAM) services are required. In this article we propose TRESSY, a scenario-building approach for CAM service up-scaling. TRESSY follows a four-step model that aims to generate mid-term projections of relevant services based on foreseeable technological and infrastructure developments. We applied TRESSY in a multi-stakeholder CAM pilot project where experts collaborated on the design of a range of up-scale service scenarios and their associated technical systems and infrastructures. The results obtained show how TRESSY can facilitate the collaboration between heterogeneous stakeholders working on representative niche, critical technical systems of future mobility.
