The Impact of Driving, Non-Driving Work, and Rest Breaks on Driving Performance in Commercial Motor Vehicle Operations
Blacksburg, VA: The Center for Truck and Bus Safety, Virginia Tech Transportation Institute, 2011. This study, sponsored by the Federal Motor Carrier Safety Administration (FMCSA), was directed at analyzing several issues regarding the commercial motor vehicle (CMV) hours-of-service (HOS) regulations. This study focuses on four key issues including driving hours, work hours, and breaks as a function of time-on-task.
Jovanis, Paul P., Kun-Feng Wu and Chen Chen. Hours of Service and Driver Fatigue: Driver Characteristics Research. University Park, PA: Larson Transportation Institute, Penn State University, 2011. In this study, qualitative and quantitative analyses of commercial motor vehicle driver hours of service were performed to assess the implications of particular policies on the odds of a crash. The outcomes studied were crashes reported by the trucking companies cooperating with the study. These crashes involved either a fatality, an injury requiring medical treatment away from the scene of the crash, or a tow away.
Hours-of-Service Rules Safety Impacts 2010 Analysis. Arlington, VA: American Transportation Research Institute, 2010. In response to the upcoming Federal Motor Carrier Safety Administration (FMCSA) Hours-of-Service (HOS) rulemaking process, the American Trucking Associations (ATA) commissioned the American Transportation Research Institute (ATRI) to examine HOS safety impacts on the trucking industry. ATRI previously studied this relationship using 2003 and 2004 motor carrier and government data.
Sando, Thobias, Michelle Angel, Enock Mtoi and Ren Moses. Analysis of the Relationship Between Operator and Cumulative Driving Hours and Involvement in Preventable Collisions. Jacksonville, FL: University of North Florida, 2010. Scientific literature strongly supports the fact that long hours of work lead to fatigue that can degrade performance, alertness, and concentration which increases safety risk. Several studies on the influence of operator schedule on collision occurrence have been conducted for other modes of transportation, particularly, the trucking industry. A thorough understanding of the correlation between transit collision occurrence and long duty hours caused by split schedules together is crucial in setting transit operating rules.
Development of Human Factors Guidelines for Advanced Traveler Information Systems and Commercial Vehicle Operations: An Examination of Driver Performance Under Reduced Visibility Conditions When Using an In-Vehicle Signing and Information System. Washington, DC: Federal Highway Administration, 1999. One of the main advantages of using an In-vehicle Signing and Information System (ISIS) is the ability to receive information inside the vehicle when elements outside the vehicle reduce or eliminate the opportunity to gather that information from the external environment. Weather conditions, such as rain or snow, can reduce the opportunity to obtain this information externally. Road geometry or foliage can eliminate the opportunity altogether. Since one of the most helpful aspects of ISIS is that it can give the driver information when it may be unavailable or untimely externally, the effectiveness of such a system under these conditions becomes a primary issue for study.
