Fatigue, sleepiness and reduced alertness as risk factors in driving

The report is based on presentations at a workshop about driver fatigue and sleepiness, organised by TØI as part of the EU project IMMORTAL in September, 2003. The following topics are presented and discussed: 1) Incidence of driver sleep, and the role of sleep and fatigue in crashes. 2) The biological basis of sleep, and medical and clinical aspects. 3) Simulator studies of fatigue indicators. 4) Eye and eyelid movements as fatigue indicators. 5) In-car warning systems to prevent falling asleep while driving. 6) Fatigue management among occupational drivers.
