AN EXTERNAL AND INFORMATION-THEORETIC CHARACTERIZATION OF SOME INTERZONAL TRANSFER MODELS

THE ACTUAL TRAFFIC STUDIES THE MEASUREMENT OF INTERZONAL TRANSFERS IS BOTH DIFFICULT AND EXTREMELY COSTLY, WHILE THE AGGREGATE TRANSFERS ARE OFTEN EASILY PREDICTED (FROM POPULATION OR EMPLOYMENT DATA, FOR EXAMPLE). THIS PAPER DEVELOPS A METHOD OF DERIVING GRAVITY MODELS FROM EXTERNAL PRINCIPLES. THE PROTOTYPE RESULT YIELDS THE MOST POPULAR GRAVITY FLOW MODEL CHARACTERIZED BY AN EXTERNAL PRINCIPLE. THIS PRINCIPLE IS ALSO FOR THE FIRST TIME ELUCIDATED AS AN INFORMATION-THEORETIC ONE OF CHOOSING THE DISTRIBUTION OF INTERZONAL TRANSFERS WHICH GIVES LEAST "INFORMATION" (IN THE TECHNICAL SENSE) FOR DISCRIMINATION AGAINST A DISTRIBUTION REFLECTING THE "FACILITY" (RECIPROCAL OF THE "DIFFICULTY") OF TRAVEL BETWEEN ZONES. /DOT/
