FOREWORD The work performed under this project included a literature review of topics related to commercial motor vehicle driver fatigue (including topics of work hours, driving time, duty periods, and restart/recovery periods) published between 2006 and July 2010. The research also included an assessment of the tasks drivers perform in a typical workday.(More)
This study examined the effectiveness of 3 different training types on commercial motor vehicle (CMV) drivers' skill levels. The training types included a conventional 8-week certified course, a conventional 8-week certified course with approximately 60% of driving time spent in a CMV driving simulator, and a Commercial Driver's License (CDL) test focused(More)
Simulator-based training provides the opportunity to train drivers in a potentially lower cost and safer environment than traditional, behind-the-wheel, training methods. Thus, many motor carriers have begun adopting simulators for use during in-house driver training. This report presents the result of focus groups with drivers who experienced truck(More)
OBJECTIVE This study examined how transitions in task demand during a driving and navigation task manifested themselves as delayed adaptation in driver mental workload. BACKGROUND A delayed reaction to changes in demand levels, termed hysteresis, has been identified in a number of settings. However, little research has specifically examined the driving(More)
This paper shows that the driving simulator may be used as a platform in which to study workload and workload performance relationship. The participants were 8 adults with valid driver's licenses. After a familiarization drive participants drove a route with five equidistant and symmetrical segments using a map and turn-by-turn directions. Upon completion(More)
