ECONOMIC EVALUATION OF TRUCK COLLISION WARNING SYSTEMS

Collision warning devices are automatic systems to warn drivers when a potentially dangerous situation occurs, and thus allow the driver to take corrective actions. This paper addresses the potential economic value of warning truck drivers of dangerous maneuvers or danger due to failure to make a maneuver. The central issue addressed by the research is the value of warning the driver when he or she is making or about to make an unintentional lane change or roadway departure. Such unintentional lane changes are a symptom of drowsiness and inattentiveness. Also evaluated were the potential benefits of warning the driver in several other potentially dangerous situations. The lack of exposure information in publicly available databases was one of the difficulties found in attempts to analyze the per mile cost of accidents by maneuver. To accomplish this analysis, a database was created to support the estimation of accident cost by accident type using accident records over a three-year period from six truckload motor carriers. Together, the six motor carriers accounted for almost 350 million miles of truck travel during the three-year period with 264 accidents. The analysis found that a collision warning system which alerted a driver to a potential accident due to an unintentional lane change or roadway departure only was not likely to be cost effective. However, a system which could warn of potentially hazardous situations when other maneuvers are being made (e.g., longitudinal warning in addition to warning during lateral maneuvers) could be very beneficial.
