Study On The Optimization Of Passenger Train Operation Plan In The Railway Corridor With Cross-line Trains

In recent years,China’s high-speed railways have been developed rapidly,and a relatively complete high-speed railway network has been formed.Therefore,high-speed railways and low-speed railways are required to transport and take responsibility jointly in railway transportation corridor,it is of great significance to coordinate operations between high-speed railways and low-speed railways.Secondly,with the rapid improvement of China’s economic level,the travel needs of the people have also changed a lot,for example,the number of trips increases,higher quality requirements of travel,and the scale of passenger flow and passenger flow have also increased.it is not just a single passenger flow and a single in the railway corridors,and these changes has caused the train operation organization to become complicated.According to the existing research,this paper studies the problem,classify passenger flows and trains,study different types of passenger flows and train operation plans,so as to meet the needs of passenger flow to the greatest extent and maximize the revenue of railway enterprises,the main research content includes the following three aspects:(1)Passenger’s perspective.Research on passenger flow in railway corridors,Summarize the types of passenger flow from the travel habits and travel needs of different passengers,this paper divides the railway passenger flow into three major types.A generalized cost function with variable weight is established,the subjective weight of passenger is introduced,and the entropy weight method is used to modify its weight in order to solve the size of different passenger flows,With the help of the general Logit model,an improved Logit model is established,and the size of different types of passenger flow is solved,in other words,the result of passenger flow sharing rate.(2)Analyze on cross-line trains,including the organization of transportation and train passenger flow.According to the research results at home and abroad,divide the transportation mode of cross-line passenger flow into two types,the first is the straight-through mode;the second is the intermediate transfer mode;transfer mode;Making a detailed analysis of the relative merits and application of the two modes,and comparing the advantages and disadvantages of the two modes.Explain the connotation of the train operation plan,focus on the analysis of the cross-line train operation plan,and clarify the principles and influencing factors when developing the cross-line train operation plan.(3)Establishing the model,considering both railway enterprises and passengers and selecting straight-through mode for cross-line passenger flow.This paper takes railway operating income,passenger fares and passenger’s travel time as the target,and takes the interval through ability,passenger flow volume demand,attendance,EMU operation and the conservation laws of passenger flow as the constraint conditions.According to the model,the corresponding genetic algorithm was designed.Finally,we provide a self-constructed instance,in order to give a case verification.
