User Perceptions of Safety and Security: A Framework for a Transition to Electric-Shared-Automated Vehicles

The data associated with this publication are within the manuscript.

The confluence of vehicle electrification, sharing and pooling, and automation alters petroleum-fueled, human-piloted, and privately-owned and operated vehicles for personal mobility in ways that raises such questions as, “Are such systems safe and secure?” and, “Who is being kept safe and secure from what (or whom)?” Answers are implied by filling in the “who” and “whom” of the second question: system, product, producer, road, and user. This white paper focuses on (actual and potential) users of systems of electrically-powered, shared, and automated vehicles (e-SAVs) as well as other road-users, e.g., pedestrians and cyclists. The role of user perceptions of safety and security are reviewed to create an initial framework to evaluate how they may affect who will initially use systems of e-SAVs for personal mobility and how safety and security will have to be addressed to foster sustained transitions. The paper will primarily be a resource for e-SAV user research, but will also inform system development, operation, and governance. This white paper offers an overarching framework grounded in the social theory of “risk society” and thus organizes past work that, typically, focuses on only one of the constituent technologies or on one dimension of safety or security, e.g., collision avoidance as a subset of road safety.
