DEVELOPING AND TESTING OF A BEHAVIORAL MODAL SPLIT MODEL

THE PAPER CONTAINS EXTENSIVE LITERATURE SURVEYS OF PSYCHOLOGY, MARKETING, SOCIOLOGY, AND ECONOMICS. IT SUBSTANTIATES THE BELIEFS THAT ATTITUDES TOWARD THE ATTRIBUTES OF TRANSPORTATION SYTEMS ARE IMPORTANT IN EXPLAINING MODAL CHOICE. A THEORY OF MODAL CHOICE WAS DEVELOPED UTILIZING THE LANCASTER APPROACH TO CONSUMPTION THEORY. IT IS HYPOTHESIZED THAT THE PERCEIVED 'INPUTS' OF ATTRIBUTES ARE LINEARLY ENTERED INTO THE UTILITY FUNCTION. DISCRIMINANT AND REGRESSION ANALYSES WERE UNDERTAKEN TO SHOW THAT PERCEPTION OF THESE ATTRIBUTES DIFFER SIGNIFICANTLY BETWEEN AUTOMOBILE AND PUBLIC TRANSIT USERS. /NTIS/
