CONSISTENCY IN DRIVER RISK TAKING

A DRIVER'S CHOICE DILEMMA AMONG OPTIONS HAVING DIFFERENT RISK LEVELS IS CONSIDERED FROM THE VIEWPOINT OF EXPECTED-COST MINIMIZATION. A RATIONAL RULE FOR SUCH DECISION MAKING IS DEVELOPED FROM STATISTICAL DECISION THEORY, SUPPORTED BY BEHAVIORAL RESEARCH ON CHOICE DETERMINANTS. THE RELEVANT PARAMETERS ARE CONSIDERED FOR POTENTIAL MODIFICATION. COMPARISON SUGGESTS THAT AN EFFORT TO RAISE THE RISK-TAKING THRESHOLD IS APT TO BE LESS SUCCESSFUL THAN ONE AIMED AT REDUCING THE INCONSISTENCY OF CHOICE BEHAVIOR WITH A GIVEN THRESHOLD VALUE. ALTHOUGH SOME TRAFFIC CONTROL INNOVATIONS MAY FULFILL THE LATTER FUNCTION, EVALUATION IS HAMPERED BY LACK OF TECHNIQUES FOR QUANTIFYING INCONSISTENCY. SEVERAL TECHNIQUES ARE PRESENTED WHICH ATTEMPT TO REDUCE THESE DECISION INCONSISTENCIES.
