Research On Operation Of Stop Plan Considering Market Competitiveness Of High-Speed Railway

The rapid growth of the national economy has promoted the vigorous development of the transportation industry.The high-speed railway network is becoming more and more dense,the road network is interconnected,and the civil aviation transportation network is continuously expanding,and the demand for passenger travel is improving day by day.At present,a variety of comprehensive transportation modes are competing for development,and the diversification of passenger travel choices has intensified the game competition among various modes of transportation in the transportation corridor.If high-speed railways want to seize the opportunity in the comprehensive transportation market and stand out,it is necessary to further optimize the transportation organization mode.As the standard for passengers to judge the service level of highspeed railway transportation organization,it is particularly important to optimize the stop plan considering the competition between high-speed railway and other modes of transportation.In the context of increasingly fierce competition in integrated transportation modes,this paper takes into account the market competitiveness of high-speed railways to optimize the stop plan.The specific research contents are as follows:1.Give the concept of market competitiveness and define the relationship between market competitiveness and passenger flow sharing rate.The relationship between the high-speed railway stop plan and market competitiveness is analyzed.Analyze the influencing factors of market competitiveness,quantitatively describe each index of market competitiveness based on the variables of the stop plan,and use the Logit model to measure the market competitiveness of high-speed railways.The Logit model was improved.2.Taking the feedback control relationship between the high-speed railway stop plan and market competitiveness,the demand for direct and transfer passenger flow,and the frequency of station service as the main constraints,establish the high-speed railway stop plan to attract the largest passenger flow and the least number of stops.Mathematical programming model for the target.Considering the exponential growth characteristics of the combination of stop variables,a new intelligent bionics algorithm,the improved discrete butterfly algorithm,is designed to solve the model in this paper.3.Taking Beijing-Shanghai high-speed railway line as an example analysis object,optimize the Beijing-Shanghai high-speed railway stop plan based on the established "stop plan optimization model considering the market competitiveness of high-speed railway".In order to verify the feasibility of the model and improve the superiority of the discrete butterfly algorithm,five groups of simulation comparison experiments are designed.The experimental results show that: based on the model and algorithm in this paper,satisfactory stopping results can be obtained.
