An Estimation Method of Modal Share of Inter-city Express Train with Consideration of Latent Preference for Transportation Modes and Screening Process for Choice Alternatives

Abstract

This study tries to develop an estimation method of modal share of inter-city express trains focusing on mode choice behavior on inter-regional trips. Firstly, the paper indicates that most of travelers are mode captive, recognizing only one transportation mode as an alternative on their mode choice behavior, and latent preference factors have impact on the generation of mode captive. Then, this study tries to develop PLCS (Parameterized Logit Captivity and Selectivity) model to describe mode choice behavior more appropriately and this study also shows that the developed simulation method with PLCS model estimates the modal share with sufficient accuracy.
