TRAVEL BEHAVIOR: RESOURCE PAPER--ATTITUDINAL MODELS

THE PAPER PLACES ALTERNATE ATTITUDE CONCEPTUALIZATIONS WITHIN THE PERSPECTIVES OF URBAN PASSENGER TRANSPORTATION PLANNING AND EVALUATION, AND DISCUSSES THE LINKAGES BETWEEN THESE CONCEPTUALIZATIONS. THE TESTING OF THE HYPOTHESIS OF TRAVEL DECISION-MAKING IS DESCRIBED. THE PSYCHOLOGICAL BACKGROUND OF THE SUBJECT IS BRIEFLY REVIEWED. IN A CONSIDERATION OF ATTITUDES AND TRANSPORTATION PLANNING, SEVERAL ISSUES ARE EXAMINED. THESE INCLUDE THE NEW-MODE DEMAND-ESTIMATION PROBLEM; THE ESTIMATION OF THE MORE COMPLETE TRANSPORTATION-DEMAND CURVE AS OPPOSED TO THE ESTIMATION OF ONLY THE DEMAND COMPONENT KNOWN AS THE MODAL SPLIT; THE LINKING OF THE TRAVEL DEMAND MODELS AND THE STRUCTURE AND GROWTH OF THE URBAN ENVIRONMENT; THE ESTABLISHMENT OF A MEANINGFUL FEEDBACK LOOP FROM DEMAND ANALYSIS TO SYSTEMS DESIGN IN THE URBAN TRANSPORTATION PLANNING PROCESS; THE LINKAGE BETWEEN DEMAND ESTIMATION AND THE SYSTEMS EVALUATION; AND THE ESTABLISHMENT OF A GENERAL DEMAND MODEL FRAMEWORK THAT CAN BE APPLIED IN A LARGE NUMBER OF METROPOLITAN ENVIRONMENTS THROUGH RECLIBRATION ONLY, WITHOUT REQUIRING BASIC CHANGES IN FORM. SPECIFICATION OF ATTITUDE TOWARD AN OBJECT IS DISCUSSED IN RELATION TO A CONSUMER THEORY POSTULATED BY LANCASTER. PREDICTION OF BEHAVIOR IS REVIEWED AND MEASUREMENT OF ATTITUDES AND OTHER PERCEPTUAL VARIABLES IS BREIFLY ENUMERATED. THE NATURE AND SCOPE OF THE ANALYSIS OF ATTUTUDE THEORY AND DEMAND FOR TRANSPORTATION IS OUTLINED. CONCLUSIONS BASED ON THIS REPORT ARE PRESENTED.
