ACCIDENT ANALYSIS OF AN URBAN EXPRESSWAY SYSTEM

STATISTICAL STUDIES BASED ON TURNPIKE ACCIDENT DATA SHOWING THE INTERACTION BETWEEN INFLUENCING FACTORS HAVE BEEN AVAILABLE FOR SOME TIME. THE ANALYTICAL TECHNIQUES DEVELOPED FOR THESE STUDIES HAVE CLEARLY HELPED TO DEFINE THE PROBLEM AND TO GIVE DIRECTION TO AN EFFECTIVE ACCIDENT PREVENTION PROGRAM. THE SAME APPROACH HAS NOW BEEN SUCCESSFULLY APPLIED TO A TYPICAL URBAN EXPRESSWAY SYSTEM. APPROXIMATELY 1,100 ACCIDENTS DURING 1956 HAVE BEEN STUDIED ON THE DETROIT JOHN C. LODGE AND EDSEL B. FORD EXPRESSWAYS. THIS PARTICULAR YEAR WAS CHOSEN BECAUSE THE GEOMETRY OF THE SYSTEM WAS UNCHANGED DURING THIS PERIOD OF TIME. SINCE THEN, ADDITIONAL SECTIONS HAVE BEEN OPENED FOR USE. PARTICULAR CARE WAS GIVEN TO AN ACCURATE ESTIMATE OF VEHICLE-MILES TRAVELED UNDER VARIOUS CONDITIONS SUCH AS WEATHER AND LIGHT CONDITIONS. THUS THE ANALYSIS IS BASED ON THE MOST COMMONLY USED INDEX OF EXPOSURE. /AUTHOR/
