Temporal Components of Warnings and Notifications for Safe Manual Re-engagement with the driving task in Automated Driving

Prior research with vehicle warnings has examined various aspects of warning designs and how they impacted driver reaction times. Further, there is prior research that explored and modeled how and at what rate drivers lose information relevant to the driving task when they remove their attention and how and at what rate they regain information upon re-engagement relevant to the situational awareness. The current project intends to build off of this foundation by further examining temporal components of warnings and manual re-engagement requests by the system (such as in SAE Level 3 Automated Driving System (ADS) equipped vehicles) with an intent to gain insights on how long does it take to build sufficient situational awareness to safely resume full manual driving depending on different types and durations of disengagement. This project will include a review of research to identify how driving automation might impact reaction times to warnings. This project will supplement this review with an empirical study of how the temporal design of warnings will impact safety outcomes for re-engagement in these circumstances.
