摘要：	This report summarizes the results of a one-year effort to establish the interaction between operating practices in the trucking industry and driver performance, particularly with respect to safety and fatigue. Principal topics were: Loading and unloading activities as they influence the likelihood and magnitude of general driver fatigue. Driver rest and recovery as it pertains to re-starting the cumulative weekly hours-on-duty clock. Length of duty period (extend driving): In this study, simulator driving performance was measured using a 14 hours on/10 hours off schedule, with schedule breaks during the 14 hour duty cycle. This study used simulator technology, which permitted safe operation in an environment that included planned safety challenges and precise measurement of driver response. The study drew the following conclusions; (1) The effects of loading and unloading were mixed. Immediately after a morning loading/unloading session, drivers' performance in crash-likely circumstances improved. Late-day loading/unloading sessions produced ambiguous results; (2) Drivers recovered baseline performance within 24 hours of the end of a driving week, and should be fit to resume duty after 36 hours; (3) a schedule of 14 hours on duty/10 hours off duty for 5-day week did not appear to produce cumulative fatigue; (4) Incidental results worthy of further study are discussed.
