Since its inauguration from year 2007, past intercity travel behaviors are changed, and transformed market shares of existing modes. Based on disaggregated choice model theory, we collected revealed preference (RP) and stated preference (SP) data form intercity passengers in Tainan to Taipei route. We also discussed this issue with behavior models of intercity mode choice and each intercity terminal access mode choice, respectively. Furthermore, we constituted an integrated model to combine intercity mode choice with terminal access mode choice by sequential calibration procedure.The model results showed concerned attributes on intercity and terminal mode choice behaviors. Also, we determined impacts on intercity travel behaviors after High Speed Rail (HSR) mode is considered, and appraised the effects of access transport on intercity mode choice. The results of intercity mode choice show that service performance factors such as in-vehicle time, out-vehicle waiting time, traveling cost, accessibility of access transport are significant affected. Variables of access time and access cost are empirical verified in access choice model. Other relevant trip and soc-economical characters as trip purpose, fellow travelers, income, occupation, possession of car, bear effects on both intercity and access mode choice behaviors, too.
Secondly, we improve the credibility of models, and discuss the advanced issue concerning correlation and heterogeneity. The great improvement on intercity and access integrated model contributed to the consideration of intercity alternative correlation. The representative performance is the correlation between HSR and domestic air service. Mixed Logit models, which take individual heterogeneity into account, are highly improving in explaining access mode choice. It corrected the scale of revealed and stated preference data, and indicated the coefficient variation of access time is lager than coefficient of access cost. Besides, we also built models in terms of segmentation to demonstrate the value of in/out vehicle time difference among pre-defined segments. The result shows that segment with relative high-income (mean income of fourteen thousands level above per mouth), involving in work trip purpose bears highest value of time; segment with low-income (mean income of fourteen thousands level below per mouth) involving in non-work trip purpose bears lowest value of time.
Finally, the study analyzes the possible change for future intercity transport market through aggregated forecast approach. The analysis of aggregated elasticity and scenario points out that travel cost is the determinant effect on market share relative to travel time. The operation adjustment of price and time from HSR administer deeply influenced on other intercity passenger transports. Moreover, the market competitive structure drew from best segmented model demonstrated the share with low-income (mean income of fourteen thousands level below per mouth) involving in work trip purpose favored HSR relative to other segments. Relevant conclusions of the study could develop specific suggestions for private and public sectors in response to transformed market after the operation of High speed rail.
