Research on the Share Rate of Passenger Flow and Transportation Organization Strategy in Railway Transportation Corridor

According to the problem of the distribution rate of passenger flow in railway transportation corridor with both high-speed railway and the existing line,the main factors influencing passengers' choice behavior between high-speed railway and the existing railway were analyzed.Based on considering economy,rapidity,convenience and comfort,a variable weight generalized cost function was set up by addition principle.Then the generalized cost function was used to replace the utility function of Logit model,a variable weight Logit model for the assignment of passenger was accordingly established. The model was used to assign the passenger flow of Wuhan-Guangzhou Railway transportation corridor.The comparative analysis of the calculation results and the actual statistical data of passenger flow indicates that the proposed model has high accuracy.The key factors which influence the development of Wuhan-Guangzhou Railway transportation corridor were analyzed.Finally,the three-stage developing strategies including cultivation period,growth period and maturity period were provided for the passenger transportation organization of Wuhan-Guangzhou high-speed railway.
