INTERSTATE SYSTEM ACCIDENT RESEARCH STUDY - I

A COMPARATIVE ANALYSIS OF ACCIDENTS, INJURIES, AND FATALITIES ON SECTIONS OF INTERSTATE HIGHWAY AS WELL AS ON COMPARABLE SECTIONS OF "EXISTING" HIGHWAY IS PRESENTED. THE INFLUENCE ON ACCIDENT EXPERIENCE OF SUCH FACTORS AS ACCESS CONTROL, HIGHWAY TYPE, TYPE OF ACCESS, AND AVERAGE DAILY TRAFFIC (ADT) IS DISCUSSED. THIS IS FOLLOWED BY AN ANALYSIS OF PROPERTY DAMAGE COSTS USING STUDY-I DATA AND PROVIDES A COMPARISON WITH SEVERAL OTHER ACCIDENT COST STUDIES. FINALLY, THERE IS A SHORT DISCUSSION OF UNDERREPORTING OF ACCIDENTS. REGARDLESS OF THE BREAKDOWN OF THE DATA INVESTIGATED OR THE MEASURE OF ACCIDENT EXPERIENCE USED, THE INTERSTATE HIGHWAYS EVIDENCED MAJOR SAFETY IMPROVEMENTS OVER THE NON-INTERSTATE HIGHWAYS. OVERALL, THE ACCIDENT, INJURY AND FATALITY RATES ON THE INTERSTATE WERE LESS THAN 50% OF THE CORRESPONDING RATES ON "EXISTING BEFORE" HIGHWAYS. IN 1975 IT IS ESTIMATED THAT THE 41,000 MILES OF INTERSTATE HIGHWAYS WILL SAVE APPROXIMATELY 7,500 LIVES, 347,000 INJURIES, 823,000 ACCIDENTS, AND $250,000,000 WORTH OF PROPERTY DAMAGE. /AUTHOR/
