reliability of simulator driving tool for evaluation of sleepiness, fatigue and driving performance

to compare the impact of extended wakefulness (i.e., sleepiness) and prolonged driving (i.e., fatigue) at the wheel in simulated versus real-life driving conditions.

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).
