EVALUATION OF THE HIGH-ACCIDENT LOCATION SPOT-IMPROVEMENT PROGRAM IN KENTUCKY

THE BENEFITS IN TERMS OF ACCIDENT REDUCTIONS DERIVED FROM A LARGE NUMBER OF LOW-COST, SPOT, SAFETY IMPROVEMENTS ARE EVALUATED. ABOUT 85 TO 90% OF THE SITES IDENTIFIED BY THE COMPUTER PROGRAM WERE FOUND, UPON REVIEW OF THE ACCIDENT REPORTS TO BE SPURIOUS-- THAT IS, THE ACCIDENTS FIT NO PATTERN OR OTHERWISE SEEMED UNRELATED TO A FEATURE OF THE ROADWAY. THIS MEANS THAT THE COMPUTER METHOD OF IDENTIFYING HIGH- ACCIDENT SITES (3 ACCIDENTS IN 12 MONTHS) CURRENTLY USED IS ONLY A CURSORY SORTING. ABOUT 65% OF THE SITES INVESTIGATED WARRANTED SOME TYPE OF IMPROVEMENT. THE EVALUATION OR ANALYSIS OF BENEFITS GAINED FROM THE PROGRAM IS BASED ONLY ON SITES INVESTIGATED IN THE FIELD. IN ONE RESPECT, THE ANALYSIS VALIDATES THE CAPABILITIES OF THE INVESTIGATING TEAM TO DISCERN CORRECTIVE MEASURES; BUT, MOREOVER, IT DEMONSTRATES THAT A HIGH DEGREE OF SUCCESS WAS ACHIEVED IN REDUCING ACCIDENTS AND THE ATTENDANT COST OF ACCIDENTS IN COMPARISON TO THE TIME AND EFFORT EXPENDED. /AUTHOR/
