DRIVER DROWSINESS, LENGTH OF PRIOR PRINCIPAL SLEEP PERIODS, AND NAPS
The purpose of this study was to assess the relationships between the prevalence of driver drowsiness observed on a trip, length of prior principal sleep periods, and naps taken during the trip, based on data collected from actual revenue runs of the Driver Fatigue and Alertness Study and the Commercial Motor Vehicle Driver Rest Periods and Recovery of Performance Study. A mathematical model was developed to describe the drowsiness data. The relative importance of time of day, last principal sleep, and earlier studies on drowsiness is also discussed.
