WAYS AND LIMITS OF INCLUDING ACCIDENT COSTS IN THE RECOMMENDATIONS FOR ECONOMIC COMPARITIVE CALCULATIONS ASSOCIATED WITH ROADS

MOEGLICHKEITEN UND GRENZEN DER EINBZIEHUNG DER UNFALLKOSTEN IN DIE RICHTLINIEN FUER WIRTSCHAFTLICHE VERGLEICHSRECHNUNGEN IM STRASSENWESEN (RWS)

THE RECOMMENDATIONS FOR ECONOMIC COMPARATIVE CALCULATIONS ASSOCIATED WITH ROADS IN THEIR CURRENT FORM CONSIDER ON THE BENEFIT SIDE ONLY THE SAVINGS IN VEHICLE OPERATING COSTS AND TIME COSTS.IN EACH CASE THESE COSTS RESULT SYSTEMATICALLY FROM A COMPARISON OF PLANNED NEW ROADS AND OLD ROADS USED BY THE ROAD PARTICIPANTS HITHERTO.AS ECONOMIC INVESTIGATIONS HAVE SHOWN,THE SAVINGS IN TIME AND OPERATING COSTS ON DIFFERENT SECTIONS DO NOT DEPEND SO MUCH ON THE VARYING DESIGN OF THE NEW SECTIONS AS ON THE SITUATION IN THE REGION OF THE OLD ROADS USED PREVIOUSLY. IN A SIMILAR FASHION VARYING SAVINGS IN ACCIDENT COSTS CAN RESULT FROM DIFFERENT ROAD CONSTRUCTION PROJECTS.THIS FACT SHOWS THAT THERE IS AN URGENT NEED TO TO CONSIDER ACCIDENT COSTS IN THE FORM OF PRIMARY AND SECONDARY COSTS (COSTS OF THE CONSEQUENCES OF ACCIDENTS) IN ECONOMIC AND PRIORITY CONSIDERATIONS IN ROAD CONSTRUCTION.THE RESEARCH PROJECT IS CONCERNED WITH WAYS AND LIMITS OF INCLUDING ACCIDENT COSTS IN THE RECOMMENDATIONS FOR ECONOMIC COMPARATIVE CALCULATIONS ASSOCIATED WITH ROADS.THE WHOLE STUDY IS TO BE DIVIDED INTO FOUR SECTIONS: IN THE FIRST STUDY AN ANALYSIS OF FACTORS WHICH DETERMINE ACCIDENTS ON THE ROADS WILL BE CARRIED OUT.THIS ANALYSIS WILL AID IN THE FORMULATION OF A THEORETICAL EXPLANATORY MODEL WHICH SHOULD BE AN ORIENTATION AID FOR THE STRUCTURE OF THE STATISTICAL ESTIMATION MODELS.THE DEVELOPMENT OF THE STATISTICAL ESTIMATION MODELS WILL BE THE SECOND STEP OF THE STUDY.THE THIRD PHASE WILL CONSIST IN THE ECONOMIC EVALUATION OF THE ACCIDENTS,AND THE FOURTH STAGE WILL DEAL WITH THE CONCRETE INCLUSION OF THE RESULTS OF THE STUDY INTO THE RECOMMENDATIONS.BASICALLY THE DATA PREPARED BY THE FEDERAL MINISTER OF TRANSPORT FOR THE 1970 ROAD EVALUATION SHOULD BE DRAWN ON FOR THE STUDY (APPROXIMATELY 15 000 TO 20 000 DIFFERENT SECTIONS OF ROAD).
