COST BENEFIT STUDIES OF TRAFFIC SAFETY MEASURES

NUTZEN-KOSTEN-UNTERSUCHUNGEN VON VERKEHRSSICHERHEITSMASSNAHMEN

COST BENEFIT ANALYSIS IS RECOGNISED AS HIGHLY SUITABLE FOR DETERMINING THE ECONOMIC EFFICIENCY OF ALTERNATIVE TRAFFIC SAFETY PROJECTS COMPARED TO COST EFFECTIVENESS ANALYSIS AND VALUE ANALYSIS. PROBLEMS ASSOCIATED WITH THE DETERMINATION AND EVALUATION OF COSTS AND BENEFITS ARE DEALT WITH, WITH SPECIAL REFERENCE TO THE AREA OF ROAD SAFETY. ON THE BENEFIT SIDE A RE-EVALUATION OF ACCIDENT COST ELEMENTS BASED ON A CONSISTENT METHOD WAS ESSENTIAL. TRAFFIC SAFETY MEASURE FACTORS WHICH HAVE TO BE DETERMINED ARE CONVERTED TO SYSTEMATIC AND VALID CALCULATIONS. THE PRACTICALITY AND COMPLETENESS OF THIS STANDARDISED COST BENEFIT DIAGRAM IS CHECKED WITH REFERENCE TO CONCRETE TRAFFIC SAFETY MEASURES.
