MULTIPLE REGRESSION STUDY OF THE EFFECTS OF SAFETY ACTIVITIES ON THE TRAFFIC ACCIDENT PROBLEM

THIS STUDY WAS AN ATTEMPT TO EVALUATE THE EFFECTS OF SAFETY ACTIVITIES ON THE TRAFFIC ACCIDENT PROBLEM. BEING AWARE THAT FATAL AND NONFATAL ACCIDENTS VARY IN FREQUENCY FROM ONE PLACE TO ANOTHER, THE BASIC EFFORT WAS CONCERNED WITH SEARCHING FOR THE REASONS FOR THESE DIFFERENCES, IN TERMS, OF SAFETY ACTIVITIES (CALLED PROGRAM FACTORS), AND OF ENVIRONMENTAL AND PHYSICAL CONDITIONS (VEHICLE AND POPULATION DENSITY, TERRAIN, WEATHER, ETC., CALLED NON- PROGRAM FACTORS). EXPERIENCE OF THE INDIVIDUAL STATES WAS USED FOR TESTING THE RELATIONSHIP BETWEEN ACCIDENTS, AND THE PROGRAM NON-PROGRAM FACTORS. THE PRINCIPAL FINDING WAS THAT THE MAJOR PORTION OF THE DIFFERENCES IN ACCIDENT EXPERIENCE IS ASSOCIATED WITH DIFFERENCES IN THE NON-PROGRAM FACTORS-- PARTICULARLY VEHICLE DENSITY, KIND OF TRAVEL, AGE OF THE POPULATION, AND WEATHER. HOWEVER, WHEN THE FATALITY EXPERIENCE WAS ADJUSTED FOR THE NON-PROGRAM FACTORS, THERE WERE LITERALLY DOZENS OF PROGRAM ACTIVITES THAT WERE SIGNIFICANTLY ASSOCIATED WITH THE DEATH RATES. THESE FINDINGS EMPHASIZE AGAIN THAT THE TRUE NATURE OF THE MOTOR- VEHICLE PROBLEM DOES NOT EVOLVE AROUND ONE OR TWO DOMINANT FACTORS. RATHER, IT EVOLVES AROUND A LARGE GROUP OF FACTORS, EACH CONTRIBUTING A SMALL BUT SIGNIFICANT SHARE TO THE TOTAL PROBLEM. /AUTHOR/
