HIGHWAY IMPROVEMENTS SUGGESTED BY ACCIDENT ANALYSIS

RECORDS OF ALL TRAFFIC ACCIDENTS, INDICATING CAUSE, LOCATION AND ACCIDENT RATE, SHOULD BE KEPT ON FILE. A COMPREHENSIVE ANALYSIS OF THIS DATA ENABLES THE HIGHWAY ENGINEER TO ASCERTAIN WHAT IMPROVEMENTS MUST BE UNDERTAKEN TO INCREASE THE SAFETY MARGIN OF A PARTICULAR HIGHWAY OR SECTION. THESE RECORDS ARE BEING KEPT IN MANITOBA AND A SAFETY-ORIENTED IMPROVEMENT PROGRAM HAS SHOWN ENCOURAGING RESULTS. WHILE, SINGLY, ACCIDENT RECORDS ARE OF NO VALUE, THEY ASSUME HIGH IMPORTANCE WHEN LINKED TO STATISTICS SUCH AS TRAFFIC VOLUME AND FLOW, DESIGN STANDARDS AND PAVEMENT SHOULDER WIDTHS. FOUR EXAMPLES OF ROAD IMPROVEMENTS RESULTING FROM ACCIDENT ANALYSES ARE GIVEN' THREE WERE INTERSECTION MODIFICATIONS AND ONE, THE RESURFACING OF A SLIPPERY PAVEMENT. /CGRA/
