Impact of Automated Vehicle External Communication on Other Road User Behavior

Road users communicate with one another in various ways (e.g. hand gestures, eye contact). There is growing concern in the industry about whether highly automated vehicles (HAVs) will be able to communicate intent to other road users in the same ways, and to the same benefits, that a human can. The investigation of potential HAV external communication systems is underway by numerous stakeholders in many countries. There is a desire by many automotive original equipment manufacturers (OEMs) to adopt a common implementation across the automotive industry to prevent road user confusion of signal meaning and maintaining safety on the roadways. While some systems show promise, there remain design parameters that stakeholders cannot agree on and their implications are misunderstood (e.g. location on vehicle, color). This proposed research study will evaluate these HAV external communication design parameters in both static and dynamic settings and from a driver or pedestrian road user perspectives.
