Fatigue during Prolonged Simulated Driving: An Electroencephalogram Study

Fatigue resulting from driving has been the subject of interest in many studies, particularly due to its pertinent role in road traffic crashes. Fatigue can be evaluated by certain indicators, such as changes in neural activity. The objective of this study was to characterize fatigue associated with prolonged simulated driving by employing electroencephalography. Fourteen male participants were recruited and asked to drive a simulator for five hours in the morning. All participants had two resting conditions the night prior to the experiment (sufficient sleep or partial sleep deprivation). Subjective responses clearly demonstrated an increase in fatigue as a function of driving duration. Data from brain wave activities, however, did not present clear, consistent changes as fatigue progressed. These findings suggest that theta waves can be used as manifestations of fatigue and temporal waves as the selected cortical area of concern.
