A GENERALIZED TRIP DISTRIBUTION MODEL

A NEW TRIP DISTRIBUTION MODEL WHICH HYPOTHESIZES STATISTICAL REGULARITIES IN TRAVEL BEHAVIOR WAS DEVELOPED. TO BEGIN THE DEVELOPMENT OF THE MODEL, OPERATIONAL DEFINITIONS OF ORIGIN EMISSIVENESS AND DESTINATION ATTRACTIVENESS WERE ADVANCED. IT WAS POINTED OUT THAT HETEROGENEOUS TRIP COSTS TYPICALLY FOUND TO EXIST IN TRIPMAKING SYSTEMS TEND TO DISTORT THE PURE TRIP PATTERNS SUCH THAT THE COST OF TRAVELING FROM EACH ORIGIN TO EACH DESTINATION MUST BE EXPLICITLY INTRODUCED INTO THE ANALYSIS. A LINEAR MODEL, FOR WHICH DATA REQUIREMENTS ARE QUITE MEAGER, WAS DEVELOPED TO ESTIMATE PARAMETERS OF THE GENERALIZED MODEL AND TEST FOR EXISTENCE OF ORIGIN AND DESTINATION EFFECTS, COST EFFECTS, AND ORIGIN-DESTINATION INTERACTIONS. THIS MODEL AND THE ENSUING ANALYSIS CONFORM TO WHAT IS KNOWN IN STATISTICS AS THE ANALYSIS OF COVARIANCE. WHILE THE HEURISTIC DERIVATION OF THE GENERALIZED INTERACTANCE MODEL PRESENTED IN THIS PAPER WAS QUITE LONG AND ARDUOUS, THERE IS MUCH TO RECOMMEND THE APPROACH. THE MODEL'S PRINCIPAL ASSET AS A HYPOTHETICAL CONSTRUCT IS THAT IT WAS DEVELOPED FROM A SET OF EXPLICIT PREMISES AND ASSUMPTIONS ON HUMAN (AGGREGATE) BEHAVIOR WITHOUT RESORTING TO QUESTIONABLE ANALOGIES FROM THE PHYSICAL SCIENCES. MOREOVER, THESE ASSUMPTIONS ARE IN THEMSELVES TESTABLE. THE MODEL DEVELOPED IN THIS PAPER IS DESCRIPTIVE--IT SEEKS TO UNCOVER THE STRUCTURE OF SOME EXISTING DATA. LITTLE CAN BE SAID ABOUT ITS PREDICTIVE ABILITY. THE PRINCIPAL USE OF THE MODEL IS TO ESTABLISH THE PRINCIPAL SOURCES OF VARIATION IN TRIP DISTRIBUTION DATA AND, CONSEQUENTLY, TO ESTABLISH SOME BASIC PRINCIPLES OF MASS BEHAVIOR.
