Crash causation research has identified inattention as a major source of driver error leading to crashes. The series of experiments presented herein investigate the characteristics of an in-vehicle information system (IVIS) task that could hinder driving performance due to uncertainty buildup and cognitive capture. Three on-road studies were performed that(More)
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)
Current hours-of-service (HOS) regulations prescribe limits to commercial motor vehicle (CMV) drivers' operating hours. By using naturalistic-data-collection, researchers were able to assess activities performed in the 14-h workday and the relationship between safety-critical events (SCEs) and driving hours, work hours, and breaks. The data used in the(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)
