| 摘要： | This is the largest and most comprehensive over-the-road study on this subject ever conducted in North Amercia. The data collected involved eighty drivers in the U.S. and Canada who were monitored over a period of sixteen weeks. A number of work-related factors thought to influence the development of fatigue, loss of alertness, and degraded driving performance in commercial motor vehicle drivers was studied within an operational setting of real-life, revenue-generating trips. These included the amount of time spent driving during a work period; the number of consecutive days of driving; the time of day when driving took place; and schedule regularity. For the amount of sleep and the four to five days of driving observed for each driver in the study, it was found that the strongest and most consistent factor influencing driver fatigue and alertness was time of day; drowsiness, as observed in video recordings of the driver's face, was markedly greater during night driving than during daytime driving. The number of hours of driving (time-on-task) and cumulative number of days were not strong or consistent predictors of observed fatigue. Numerous other findings are provided relating to scientific methodologies and fatigue. |
