| Summary | The purpose of this paper is to examine the effects of new transportation modes on passengers’ choice behavior and existing transportation market. We combined the two concepts of choice set and market positioning to construct an integrated model considering two choice situations simultaneously. The utility function of the integrated model was divided into two stages, choice set and alternative choice. The specification of factor structure was used to capture the individual heterogeneity and marketing positioning of the alternatives in the second stage, and the effects of new modes on choice behavior and market structure were studied by hypothesizing coefficients’ specifications in the joint estimation process. A customized computer survey was designed to collect the stated preference data of intercity passengers. The results show that the integrated model has better explanatory power than those models considering choice set or market positioning alone. The introduction of high speed rail results in increased negative passenger perceptions of travel time, but no significant difference in individual preference heterogeneity is observed. Tze-Chiang train and UNI airline are threatened mostly by high speed rail. |
