STUDY OBJECTIVE: To compare the impact of extended wakefulness (i.e., sleepiness)
and prolonged driving (i.e., fatigue) at the wheel in simulated versus real-life
DESIGN: Participants drove on an INRETS-MSIS SIM2 simulator in a research
laboratory or an open French highway during 3 nocturnal driving sessions. A
dose-response design of duration of nocturnal driving was used: a 2 h short
driving session (3-5 AM), a 4 h intermediate driving session (1-5 AM) and an 8 h
long driving session (9 PM-5 AM).
PARTICIPANTS: Two groups of healthy male drivers (20 for simulated driving and 14
drivers for real driving; mean age±SD=22.3±1.6 years), free of sleep disorders.
MEASUREMENTS: Number of inappropriate line crossings, self-rated fatigue and
sleepiness were recorded in the last hour of driving sessions to control the
effects of prior waking time and time of day.
RESULTS: Compared to the daytime reference session, both simulated and real
driving performance were affected by a short nocturnal driving session (P
