INVESTIGATIONS OF THE EFFECT OF TRAVELER ATTITUDES IN A MODEL OF MODE-CHOICE BEHAVIOR

Abstract

ATTITUDINAL DATA WAS USED TO PREDICT INDIVIDUAL MODE CHOICE. TRAVEL IS VIEWED AS A FORM OF HUMAN BEHAVIOR TO WHICH THE APPROPRIATE SOCIOLOGICAL AND PSYCHOLOGICAL PRINCIPLES MAY BE APPLIED. A MODEL OF INDIVIDUAL MODE CHOICE IS FORMULATED, BASED ON THE TRAVELER'S ATTITUDES TOWARD QUALITATIVE SYSTEM CHARACTERISTICS. AN INDEX IS DEVISED TO PRESENT THE RELATIVE QUALITY OF TRANSIT AUTOMOBILE TO THE TRAVELER AND IN THEN RELATED TO ACTUAL MODE CHOICE. THE CHOICE MODEL IS MADE OPERATIONAL BY MERGING AN ATTITUDINAL DATA SET WITH A FILE OF TRIPS BASED ON THE CHARACTERISTICS OF TRIPS AND TRIPMAKERS. A SERIES OF TESTS EXAMINES THE SENSITIVITY OF THE MODEL TO CHANGES IN SEVERAL QUALITATIVE SYSTEM ATTRIBUTES. /AUTHOR/
