Analysis of driver task-related fatigue using driving simulator experiments

In this paper passive task-related effects of highway driving in monotonous environments were studied using driving simulator experiments. Seventeen drivers were asked to drive in monotonous and various environments in the morning (9:00-11:00 a.m.) and in the early afternoon (1:00-3:00 p.m.); the Mean and the Standard Deviation of Steer Error and the Standard Deviation of Lateral Position, calculated on sub-interval of 1 minute, were recorded and chosen as response variables. The analysis conducted using mixed-effects models highlighted negative influence of the duration of driving task, monotonous environment and circadian effects in decrements of driving performances.
