Interactions Between Automated Vehicles and Pedestrians and Bicyclists: A Literature Review

This project will provide information on behavioral safety considerations surrounding interactions between automated vehicles (AVs) and pedestrians and bicyclists so that NHTSA can develop countermeasure programs to help reduce the number of pedestrian and bicyclist injuries and fatalities. A literature review will be conducted to investigate the current knowledge surrounding safety considerations for pedestrians and bicyclists when interacting with AVs. As a whole, the body of automated vehicle research is rapidly expanding; however, details of safety and interactions of pedestrians and bicyclists with AVs are limited. Some of the safety issues to consider when looking at these interactions include, but are not limited to, detection problems on the part of the AV, lack of communication of intent between AVs (e.g., lights and signals, passenger-carrying and non-passenger-carrying) and pedestrians and bicyclists (e.g., gestures and facial expressions), right of way laws that differ by jurisdiction and State, pedestrians and bicyclists feeling more confident of AV movements (leading to both positive and negative outcomes - more walking/bicycling, maneuvering into traffic, over-trust of AVs, hostility/gaming), and traffic flow and pattern changes (e.g., more congestion, pedestrians crossing at unspecified locations).
