DEVELOPMENT OF HIGHWAY SAFETY STATISTICAL INDICATORS

A SET OF STATISTICAL INDICATORS WERE DEVELOPED TO EVALUATE THE NATIONAL ROAD SAFETY SITUATION USING AN ECONOMIC LOSS MODEL WHICH RELATES PHYSICAL DAMAGE FROM COLLISIONS TO THE RESULTING COSTS. THE ACCIDENT DATA WERE DIVIDED INTO EXPOSURE CLASSES BASED ON THE SIGNIFICANT TRENDS INFLUENCING THE ROAD ACCIDENTS AND THE RESULTING ECONOMIC LOSS. TWO INDICES WERE DEVELOPED: (1) A VALUE INDEX WHICH MEASURES THE LEVEL OF AND THE CHANGE IN ECONOMIC LOSS OVER A GIVEN PERIOD: AND (2) A REAL COST INDEX WHICH CAN BE ADJUSTED TO ALLOW FOR PRICE CHANGE AND VEHICLE MILES TRAVELLED, AND WHICH MEASURES THE TREND IN ROAD ACCIDENTS AND INJURIES IN TERMS OF ECONOMIC LOSS. THE MODEL AND THE INDICES WERE TESTED ON THE STATE OF WISCONSIN'S ACCIDENT RECORDS: IT WAS FOUND THAT THE INDICES WERE REASONABLE INDICATORS OF THE OVERALL ROAD ACCIDENT SITUATION. THE COMPUTER PROGRAM IS APPENDED. /TRRL/
