RELATIONSHIP BETWEEN LIGHTING AND ACCIDENT EXPERIENCE BETWEEN INTERCHANGES
THE RELATIONSHIP IS EXAMINED BETWEEN ACCIDENT EXPERIENCE AND LIGHTING BETWEEN INTERCHANGES OF THE INTERSTATE HIGHWAY SYSTEM IN URBAN AREAS. CHARACTERISTICS CONSIDERED INCLUDE EXISTENCE OF LIGHTING, NUMBER OF LANES, INTENSITY OF LIGHTING, AND AVERAGE DAILY TRAFFIC VOLUME. ACCIDENTS PER HUNDRED MILLION VEHICLE-MILES OF TRAVEL ARE USED AS THE PRIMARY INDICATOR OF ACCIDENT EXPERIENCE. RESULTS INDICATE THAT 24-HOUR ACCIDENT RATES AND NIGHT (6 P.M. TO 4 A.M.) ACCIDENT RATES ARE HIGHER ON LIGHTED HIGHWAYS THAN ON UNLIGHTED HIGHWAYS REGARDLESS OF WHETHER MAINLINE UNITS ARE CLASSED BY NUMBER OF LANES OR BY ACT LEVELS. AVERAGES OF VARIOUS GEOMETRIC, TRAFFIC, AND ACCIDENT CHARACTERISTICS FOR LIGHTED AND FOR UNLIGHTED UNITS WERE COMPARED AND DISCREPANCIES NOTED. THERE IS NO DISCERNIBLE RELATIONSHIP BETWEEN LIGHTING INTENSITY AND ACCIDENT RATE ON 2-LANE MAINLINE UNITS OR 3-LANE MAINLINE UNITS. /AUTHOR/
