Watch the video, in which Anna Anund (Research Director at VTI), elaborates on this study: A WP1-paper on driver sleepiness under L2 automated driving has just been published in Accident …

Effects of partially automated driving on the development of driver sleepiness

Fatigued drivers show slower visual processing, loss of selective attention, poor distractor inhibition, reduced peripheral processing capacity as well as lapses and wake state instability. This leads to worsened decision making, slower reaction times, reduced attention to the forward roadway and driving performance incapability. Fatigue related crashes typically occur during night-time or in the …
