EVALUATING HIGHWAY SAFETY PROJECTS: A GUIDE FOR ADMINISTRATORS

THE REPORT IS AIMED AT THREE PROBLEMS: WHAT TO MEASURE, HOW TO MEASURE, AND WHEN TO MEASURE. IT IS NOTED THAT IT IS OFTEN DIFFICULT TO MEASURE THE DESIRED RESULT ITSELF, OR AT LEAST TO ASCRIBE IT TO THE PARTICULAR SAFETY COUNTERMEASURE, SO OTHER EVENTS AND EFFECTS MUST BE CHOSEN TO SERVE IN THEIR PLACE. A METHOD CALLED THE "CAUSAL CHAIN APPROACH" IS EXPLAINED THAT ESTABLISHES A LOGICAL ORDER OF EVENTS OCCURRING BETWEEN THE COUNTER-MEASURE IMPLEMENTATION AND THE ULTIMATE EFFECTS. ANY ONE OF THESE EVENTS CAN BE SELECTED AS A PROXY FOR THE ULTIMATE BENEFIT, BUT ITS POSITION IN THE CHAIN DETERMINES THE CONFIDENCE WITH WHICH THE RESEARCHER CAN ASCRIBE THE EFFECT TO THE COUNTERMEASURE. RECOMMENDATIONS ARE MADE FOR SETTING UP SAFETY COUNTERMEASURE PROGRAMS, CONDUCTING A PREPROJECT EVALUATION, MONITORING ON-GOING PROJECTS, AND EVALUATING THE RESULTS OF SUCH PROJECTS.
