A valid assessment of motor vehicle crash risks and the potential impact of safety interventions requires a precise understanding of the types of vehicles likely to be equipped and otherwise affected, the most relevant referent to the intervention (e.g., national annual crash total, vehicle mileage, and vehicle life), and the scope of monetary crash costs to be considered. This paper analyzes to U.S. police reported motor vehicle crash involvement type/role (e.g., single vehicle roadway departure, left turn across the path); subject vehicle body type (i.e., passenger cars, light trucks/vans, heavy combination unit trucks, medium/heavy single unit trucks, and motorcycles); type of metric (i.e., crashes, involved vehicles, persons killed/injured, and monetary cost); and problem size referent (i.e., U.S. annual, per cash, per vehicle. per driver, and per mile traveled). |
