Research On Optimization Of Passenger Train Connection Scheme In Large Transfer Station

With the gradual completion of the high-speed railway network,by 2030 the railway network will basically achieve internal and external interoperability and completely cover major cities in China.The railway can meet the travel needs of almost any people.As more and more travelers choose to travel by rail,most travelers who choose to travel by rail will have transit problems on their way.In this context,it is of great significance to study the optimization of passenger train transfer plan for a single large transfer station in high-speed railway network.The main contents include:(1)Firstly,define the connection problems of passenger trains at large transfer stations,and conclude that the optimization of train connecting solutions of transfer stations can transform into the sequencing and stopping schedules of trains at stations,and then analyzes the passenger trains of transfer stations Continued optimization program’s role.Then the theoretical foundation and proper nouns of the train connection plan are introduced,and the basis of the connection plan optimization is the train operation plan.Finally,the factors that affect the passenger train connection in the transfer station are analyzed.(2)The transfer process of passenger transfer station is analyzed,and the result shows that the transfer time of station passenger is composed of passengers getting on and off the train and walking time in the station.At the same time,the transfer of the train at the transfer station is analyzed,mainly from the follow-up train time interval and the direction of the continuation of the transfer station train connection analysis,summed up the different types of train connection interval and consider the different directions of the train Followed by the characteristics of the passenger train derived from the connection characteristics.(3)Through the preceding analysis of the transfer station after the train to connect,come to the train connection program optimization program design options.Then,based on some assumptions of the model,the parameters and variables of the interchange model of train interchange are designed,and the objective function is to determine the effective transfer of passengers as much as possible and to reduce the invalid waiting time of the transfer passengers at the station.The model of passenger train connection optimization of transfer station has never been considered without considering the origin of the train and the train connection relationship has been established.Then,the model of passenger train connection optimization is established step by step,and then the relevant model is established based on the premise that the departure train and the train connection are established.Finally,Consider the continuation optimization model of the passenger train at the transfer station where the terminating train arrives and the train connection is undetermined.(4)The model was solved by using MATLAB software for programming,Then,on the assumption of the relevant examples,the model is used to arrange the train at the transfer station in a certain cycle of the transfer station,stopping time and sorting,provide the basis for the preparation of the train operation diagram.
