SLEEPINESS AT THE WHEEL A SUMMARY OF THREE STUDIES OF THE DROWSI PROJECT

摘要

In the Swedish project “DROWSI” three experimental studies (which manipulated the level of sleepiness) have been carried out. One study was a simulator study, whereas the other two studies were carried out in real traffic. The purpose of the studies was to search for sensitive indicators of sleepiness at the wheel and to develop drowsiness detection systems combining sensor input to deliver criteria for feedback (warnings) to the driver. The studies have identified a number of promising sleepiness indicators, e.g. a generic lane variability indicator, that can be included in sleepiness detection and warning systems.
