ECONOMIC EVALUATION OF TRUCK COLLISION WARNING SYSTEMS
Collision warning devices are automatic systems to warn drivers when a potentially dangerous situation occurs, thus allowing drivers 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. For example, 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 are the potential benefits of warning the driver in several other potentially dangerous situations. One of the principle difficulties found is the lack of publicly available databases to support analysis of the per mile cost of accidents by maneuver. The primary deficiency of publicly available accident databases is the lack of exposure information. To create a database which supports the estimation of accident cost by accident type, the accident records, over a three year period, of six truckload motor carriers were compiled. Together, the six motor carriers accounted for almost 350 million miles of truck travel during the three year period. During this period, there were 264 accidents. The analysis found that a collision warning system which only alerted a driver to a potential accident due to an unintentional lane change or roadway departure 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.
