Abstract Abstract : Research purposes ： The study of passenger travel mode choice in transportation corridor is the great significance for tlie rational planning of transport corridors and the integration of transportation resources. At present，the prediction accuracy and explanatory of the analytical model are insufficient. In order to improve the accuracy and explanatory of model， the paper uses structural equation modeling technique to study the relations between the observable and latent variables， and constructs transportation corridor SEM - MNL integrated model that covers observable and latent variables. The model includes travelers latent psychological factors to the utility function based on the mechanism of travel. As an example， an empirical analysis is carried out in Chengdu - Chongqing transportation corridor. Research conclusions:( 1 ) The latent variables have a significant influence on the choice decision of the traveler. (2) The results showthat goodness of fit of the integration model that added latent variable are better than the traditional model，the accuracy rate is also increased dramatically. (3 ) The research results can be applied to the structure analysis and configuration of transportation corridor.
