A Dynamic Generalized Cost Based Logit Model for Passenger Corridors

In order to scientifically compute the supply allocation of various transportation modes for passenger corridors, a dynamic generalized transportation cost based Logit model is proposed according to the theory of random utility and discrete choice model. The model's robustness and accuracy were verified via MATLAB programming using the Zhengzhou-Xi'an Passenger Corridor as a study case. The analysis result indicates that transportation construction cost changes with the share, which is influenced by travel time and the random perception coefficient. Compared with existing models, the changes of sharing rate and that of transportation construction costs in this paper are not in the same direction. For the dynamic changing of generalized transportation costs, the sharing rate calculated only by a static travel time and ticket price is unreliable. The model proposed in this paper cannot only meet the individual demands of travelers, but can also keep the sustainable operation of transportation. The sharing rates calculated by the model for the Zhengzhou-Xi'an Passenger Corridor are more reasonable than those calculated by traditional models.
