Abstract:

As automated vehicles (AVs) become more prevalent on the roadway, drivers are becoming interested in the benefits that they may provide. An AVs potential to perform driving tasks for tired individuals is appealing for those who are at risk of drowsy driving. This manuscript covers three studies on this topic. In Study One, participants were placed in 30-minute simulated drives after performing fatiguing tasks. Survey and physiological data were analyzed to examine the impact of acute fatiguing tasks. Study Two used the same experimental tasks with participants who experienced high levels of fatigue in their day-to-day life. Study Three sought to gather the opinions of these fatigued groups regarding the use of AVs to mitigate drowsy driving. Collectively, these studies aimed to inform decision-makers of the factors that should be considered in a driver’s choice to use automation while fatigued.
