Abstract:Driver fatigue is recognized as a major factor in the safety of long-haul commercial driving. Sleeper berths are often provided on tractors to allow the driver to sleep and rest when not driving. However, the sleeper berth environment and/or the manner in which drivers actually use sleeper berths may effect the quality of their sleep. This tech brief summarizes the first task in a 4-year study to assess the impact of sleeper berth usage on the level of driver alertness and driving performance. This task consisted of a literature review and 10 focus groups conducted with 74 long-haul commercial motor vehicle (CMV) drivers. Researchers sought to gain an understanding of the issues affecting the quality and quantity of sleep drivers receive, as well as other issues that may affect drivers' levels of fatigue and driving safety. 2 p.
