PERCEPTION OF THE AVAILABILITY OF TRANSPORTATION ALTERNATIVES FOR VARIOUS TRIP PURPOSES

Mode choice models require five decisions concerning model structure. These are the selection of (a) a statistical technique, (b) the method of comparing the characteristics of competing modes, (c) the method of representing socioeconomic variables, (d) objective or subjective measures of times and costs, and (e) objective or subjective criteria for separating those who choose among modes from those who are captive to a mode. The purpose of this paper is to examine the implications of the subjective approach to separating choosers from captives. To do this, various models that distinguish choosers from captives are developed. The data were obtained from a stratified probability sample of 223 households from the Santa Monica-west Los Angeles, California, area. Variables distinguishing choosers from captives for the work trip and the most frequent nonwork trip as well as personal and locational descriptors of the individual and information on the characteristics of the competing modes were available. Logit analysis was used to test the alternative models, and the conclusion reached was that models containing specific information about the characteristics of the competing modes were superior to models containing only locational and personal information on individuals. The implications of this finding in terms of predicting modal split, understanding transportation behavior, and transportation policy are noted. /Author/
