Fatigue has major implications in transportation system safety. Investigating the psychophysiological links to fatigue can enhance our understanding and management of fatigue in the transport industry. This study examined psychophysiological changes in thirty-five subjects randomly assigned to a driver simulator task. Electroencephalography changes during fatigue were significantly different to the alert baseline (p<0.01). Delta and theta activity increased the most from fatigue during simulated driving. Heart rate was significantly lower after the driving task (p<0.01). Blink rate also changed in association with fatigue. We conclude that significant physiological changes occur during driver fatigue. The results are discussed in light of directions for future studies and for the development of a fatigue counter measure device.
