abstract="The study compares the external costs of road traffic accidents in different European countries and finds substantial differences in the external costs per vehicle-kilometre. It also finds that lorries and buses generate substantially higher external costs than passenger cars because pedestrians, cyclists, motor-cycle riders, and the occupants of passenger cars, face greater hazards from lorries and buses when a collision occurs.<p />",
