A general theory of fatigue developed during an extensive study of aircrew fatigue is described, and its application to driving fatigue is attempted. From the theory, four specific predictions can be made: (a) Effects of extended performance are likely to be of less significance than effects of lack of sleep; (b) Severe fatigue effects are likely to be confined mainly to the professional driving population, more particularly the long haul transport operator; (c) Measurable decrement in quality of driving performance is likely to be small, even after extended periods of driving; (d) A complex interaction between lack of sleep, motivational factors and task variables is to be expected, such that an increase in task demand will be matched by increased effort, and will not produce any significant decrement in driving performance. The critical condition is likely to be an extended period of uneventful driving when the driver has accumulated a sleep deficit. /HSRI/
