Closing the gap between science and practice in the prediction of drowsinessrelated driving events

EXTENDED ABSTRACT: Drowsy driving remains a significant contributing factor to road crashes. This paper assesses the recent developments in the detection and prediction of drowsiness-related driving events. The research reviewed here has confirmed that drowsiness can have a serious impact on driving performance in controlled, experimental settings. New findings from on-road studies however show different impacts on performance although few studies have characterised precise relationships between drowsiness and driving performance. The measurement of drowsiness-related events has progressed and recent research suggests that subjective ratings, blink duration and steering metrics show promise in being effective predictors of drowsiness-related driving events.
