Research On Differential Pricing Method Of High Speed Railway Passenger Transport Products Considering Passenger Travel Choice

At present,the difference in travel time,departure time of trains and passengers'preferences cannot be expressed through fares due to the same fare price of the same level of high-speed railway trains between the same starting and terminal stations.The passengers'choice preferences directly affects the revenue of the high-speed railway.Therefore,the preferences needs to be considered when determining the fare.Based on the existing research results at home and abroad,this paper considers the passenger travel choice behaviors and studies the differential pricing method for the same level seats of different trains.The main research works are as follows:Firstly,starting from the high-speed railway ticket pricing theory,the concept of differential pricing is introduced,and the necessity of differential pricing for high-speed railways in China is pointed out,and the applicable conditions for applying differentialpricing to high-speed railways in China are explained.Combined with the passenger travel choice behavior theory,the high-speed railway differential pricing strategy under the influence of passenger travel choice is proposed.Secondly,8750 valid data have been taken by SP survey method for passengers from Beijing to Xi'an and Beijing to Guangzhou.Conduct basic analysis and cross-analysis on the data obtained from the survey to understand the basic attributes and travel attributes of the survey passengers.The SP survey data is used to construct the passenger travel choice behavior model and parameters estimation.The passengers'willingness to pay for shortening the running time and changing the departure time is obtained.Thirdly,considering the fare,running time,departure time,etc.,the generalized cost function of passenger travel is established.Based on the user equilibrium theory and taking into account the interests of both high-speed railway enterprises and passengers,a bi-level programming model for differential pricing of high-speed railway passenger products is constructed,and solved by a heuristic algorithm for sensitivity analysis.Finally,the bi-level programming model of differential pricing is used to obtain the optimal pricing and corresponding passenger flow of different passenger products.The high-speed railway revenues of existing unified pricing and differential pricing model are compared and analyzed,and the rationality of differential pricing is illustrated,verifying the validity of the model.
