The purpose of this paper is to examine the effects of new transportationmodes on passengers’ choice behavior and existing transportation market. Wecombined the two concepts of choice set and market positioning to construct anintegrated model considering two choice situations simultaneously. The utilityfunction of the integrated model was divided into two stages, choice set andalternative choice. The specification of factor structure was used to capture theindividual heterogeneity and marketing positioning of the alternatives in thesecond stage, and the effects of new modes on choice behavior and marketstructure were studied by hypothesizing coefficients’ specifications in the jointestimation process. A customized computer survey was designed to collect thestated preference data of intercity passengers. The results show that theintegrated model has better explanatory power than those models consideringchoice set or market positioning alone. The introduction of high speed railresults in increased negative passenger perceptions of travel time, but nosignificant difference in individual preference heterogeneity is observed.Tze-Chiang train and UNI airline are threatened mostly by high speed rail. |
