External Communication on Other Road User Behavior Study Data (VTTI-00-027)

Project Description: The purpose of this study was to evaluate specific HAV external communication design parameters in both static and dynamic settings and from a driver or pedestrian road user perspectives. Data Scope: Forty participants observed external communication displays on two vehicles that emulated L4+ AVs. Every participant viewed eight different testing scenarios that were repeated for multiple trials. The eight scenarios were split between pedestrian and passenger perspectives. When participants were experiencing the pedestrian scenarios, they would make crossing decisions and complete rankings on their understanding of the displays. When participants were experiencing the passenger scenarios, they would observe the scenario and complete ratings on their understanding.
