This document summarizes Socioeconomic Impacts of Automated and Connected Vehicles, a symposium held June 26–27, 2018, at the Hotel NH Brussels Bloom in Brussels, Belgium. Hosted by the European Commission and the Transportation Research Board (TRB) of the National Academies of Sciences, Engineering, and Medicine (the Academies), it was the sixth annual symposium sponsored by the European Commission and the United States. The goals of these symposia are to promote common understanding, efficiencies, and trans-Atlantic cooperation within the international transportation research community while accelerating transport-sector innovation in the European Union and the United States. The 2-day invitation-only symposium brought together high-level experts to share their views on the socio economic impacts of connected and automated vehicles and shared mobility (CAVSM). With the aim of fostering trans-Atlantic collaboration in research and deployment, symposium participants discussed challenges and opportunities arising from the diffusion of CAVSM and innovative approaches to mitigate any negative socioeconomic impacts.
