Abstract

An increasing number of traffic accidents are attributed to distracted driving, encompassing both mind wandering (MW) and secondary task-related distractions. Autonomous vehicles (AVs) have various support features to reduce these safety issues. However, given that AVs on the road are not fully autonomous, human drivers are still required to be ready to take over where the system encounters limitations. Studying the driver's mental state during the takeover process becomes vital. Signal displays have been confirmed as an effective means of alerting drivers to takeover requests, yet there remains a paucity of studies investigating the effectiveness of multimodal displays in AVs. This study aims to compare the impacts of internal distraction (mind wandering) and external distractions (secondary tasks) on takeover performance in partially automated vehicles and how multimodal displays (comprising visual (V), tactile (T), and visual + tactile (VT) elements) can effectively notify drivers of a takeover request. A human subject experiment will be implemented, and the insights garnered from this study will guide the future design of AVs while also contributing to the development of a mental model to predict drivers' takeover performance when distracted.
