CORRELATION OF DESIGN CHARACTERISTICS AND OPERATIONAL CONTROLS WITH ACCIDENT RATES ON URBAN ARTERIALS
A MAJORITY OF NON-FATAL INJURY-CAUSING COLLISIONS HAPPEN IN URBAN-AREAS WHERE ABOUT HALF THE TOTAL VEHICLE MILES ARE DRIVEN ANNUALLY. MOST CURRENT HIGHWAY ACTIVITY IN URBAN AREAS IS FOCUSED ON FREEWAY AND EXPRESSWAY DEVELOPMENT, FORGETTING THE ROLE OF URBAN STREETS AS ARTERIAL HIGHWAYS. ONE HUNDRED SECTIONS OF URBAN ARTERIALS WERE ANALYZED AND THEIR ACCIDENT DATA STUDIED AND RATES STUDIED USING MULTIPLE LINEAR REGRESSION ANALYSIS. ACCIDENT RATES WERE PREDICTED USING 26 INDEPENDENT VARIABLES. SECTIONS WITH THE SAME VOLUME BUT DIVERGENT ACCIDENT RATES WERE COMPARED IN 15 CASE STUDIES. CONCLUSIONS ARE PRESENTED ON CONDITIONS IN WHICH ACCIDENTS MAY DECREASE, ON ACCIDENT LOCATIONS, AND ON THE MEANS USEFUL TO STUDY THE DATA. /HSL/
