As Automated Vehicles diffuse through the transportation system, it is important to understand their safety performance. Although few AV-involved crashes have occurred on roads during testing, they pose new challenges and opportunities for improving safety. The challenges come from using complex automation technologies operating at high speeds to make lateral and longitudinal control decisions, increasing the chances of software and hardware failure. Are vehicles with lower or higher automation safe enough to drive on public roads, and more fundamentally, how do we assess their safety envelope? At the same time, there are opportunities to understand AV-involved crashes by leveraging newly available AV data. In this CSCRS project (reporting on Year 1 activities), we take steps toward developing testing procedures for connected and automated vehicles by using a novel software and physical deployment platform which allows rapid iterative development.
