Abstract:

Vulnerable road users (VRUs), including pedestrians, bicyclists, motorcyclists, and various micromobility users, account for a significant share of roadway fatalities. VRUs are at the most risk in urban areas, and, thus, urban areas are a focus area for implementing new transportation technologies. These new technologies include automated driving systems (ADS) and cooperative driving automation (CDA), which can potentially have positive or negative effects on VRU safety.

 

This literature review documents the potential impact of ADS-equipped vehicles and CDA technology on VRU safety and the potential role of infrastructure in facilitating safe interactions. This review discusses the factors that currently influence VRU collision rates, especially in high-risk urban areas. It also examines the capabilities and needs of ADS-equipped vehicles when interacting with VRUs and the additional positive and negative impacts that the deployment of CDA technologies are likely to have on VRU safety. Finally, the review includes a prioritized list of research gaps and safety risks that were identified by a panel of ADS and VRU experts who met to discuss the potential challenges associated with ADS-VRU interactions.
