Assessing the effect of lack of sleep on driver's performance : a simulator study

Abstract EN

Science evidence suggests that fatigue due to lack of sleep is a major cause of mosttraffic accidents.

Fatigue can arise when people do not get enough sleep, which isat least 7 hours, and this deprivation can impair body performance physically andmentally while driving.

This study investigated the effect of sleep deprivationfatigue on driving performance.

Experiments were performed for two types oftasks, Fatigue driving tasks (sleep deprivation) and non-Fatigue driving tasks(without sleep deprivation) on a driving simulator at the University of Technology, in which 42 participants; aged (19-55) took part with an average age (mean =33.14, SD = 10.26).

Driver performance was assessed using descriptive methodsto verify response time and subjective behavior methods using the StanfordDrowsiness Scale.

The results showed a gradual increase in the average responsetime of the fatigued drivers compared to the non-fatigue drivers.

The results of theresponse time indicated that all groups were affected by the test conditions, through the variation in the average response time between the two tasks.

In arelated context, the results of the Stanford Drowsiness Scale show a significantincrease in the average degree of drowsiness for fatigue drivers, as it was greaterthan for non-Fatigue Science evidence suggests that fatigue due to lack of sleep is a major cause of mosttraffic accidents.
