DEVELOPMENT OF SYSTEMS FOR ASSESSING THE EFFECTS OF VARIOUS SPEED REGULATIONS ON FEDERAL MOTORWAYS

ENTWICKLUNG VON BEWERTUNGSSYSTEMEN ZUR BEURTEILUNG DER AUSWIRKUNGEN UNTERSCHIEDLICHER GESCHWINDIGKEITSREGELUNGEN AUF BUNDESAUTOBAHNEN

IT IS SUGGESTED THAT ASSESSMENT OF THE EFFECT OF VARIOUS SPEED LIMITS IS CARRIED OUT WITH THE AID OF THREE PARALLEL EVALUATION SYSTEMS: (A) VALUE ANALYSIS; (B) COST-BENEFIT ANALYSIS, AND (C) A COMBINED PROCEDURE. THE VALUE ANALYSIS SYSTEM CONSISTS OF A SEQUENCE OF STEPS FROM SIMPLE MAJORITY TESTS TO THE ESTABLISHMENT OF ECONOMIC VALUE NUMBERS BY MEANS OF CARDINAL VALUE FUNCTIONS. THE DECISION MAKER IS CONTINUOUSLY INFORMED DURING THE PROCESS OF THE REQUIRED AMOUNT OF INDIVIDUAL SUBJECTIVE DATA. THE SYSTEM COST-BENEFIT ANALYSIS COMPRISES COMPREHENSION, EVALUATION AND SUMMARISING PROPOSALS FOR THE EFFECTS SUCH AS SAFETY, COSTS AND TIME REQUIREMENTS WHICH CAN BE QUANTIFIED IN MONETARY TERMS. THE VARIATION OF THE NATIONAL WEALTH POTENTIAL IS USED AS AN INDICATOR. THE COMBINED EVALUATION SYSTEM IS BASED ON A VALUE ANALYSIS WHICH INCLUDES THE COST-BENEFIT CALCULATION AS ONE OF THE OBJECTIVES. THE INNER WEIGHTING OF THE MONETARY CALCULATIONS CORRESPONDS TO COST-BENEFIT ANALYSIS, WHILE THE EXTERIOR WEIGHTING AND THE DECISION MAKING PROCESS ARE BASED ON THE CONCEPT OF CARDINAL ECONOMIC VALUE SYNTHESIS.
