Research On The Train Operation Plan Of High-speed Railway Off-line Train Based On Different Stopping Scheme

In recent years,with the continuous construction of high-speed railway,the high-speed railway has gradually been operated as a network,making passenger flow attraction capacity increased significantly.Off-line passenger flow ratio also shows a growing trend.To meet the needs of off-line passenger flow,the railway department has increased the number of off-line trains and proposes high demand for both high-speed lines and existing lines in China.Firstly,a better off-line train operation plan can increase the service range of the high-speed train and improve the passenger direct rate as far as possible.Secondly,it can reduce the transfer time of passengers and make passengers feel more comfortable during the journey.Finally,it can reduce the transport pressure of existing lines and maximize the revenue of the railway sector.Designing an off-line station directly affects the passenger's travel convenience and attendance,and affects the revenue of the railway department.Therefore,the study of the opening scheme for high-speed railway off-line train running is very important.On the basis of reference to both domestic and foreign research,this paper mainly studies the contents as follows:(1)By collecting current research of off-line train related to the high-speed off-line railway,key problems that need to be further studied have been pointed out.(2)Using the theories of the off-line train opening scheme for the high-speed railway,this paper analyzes the composition and characteristics of the passenger flow of high-speed railway.The definition of the train opening scheme and the stop plan of the high-speed railway have been explained,and the influence factors of the open Line scheme has been analyzed.(3)Combined with the behavior of cross-line,the trains in the railway corridor are divided into four types of trains.The symbols and variables that need to be used are explained.From the perspectives of both passenger and railway departments,aiming at the minimum passenger travel expenditure and the minimum operating cost of railway Department,a multi-objective planning model for the opening scheme of high-speed railway off-line train has been carried out.The suitable genetic algorithm for the optimization model is designed and realized.(4)Based on the existing research on the train stop scheme,considering the influence of the stop-line scheme,taking the minimum cost of train stop as the objective function,the optimization model and correlation genetic arithmetic of high-speed railway off-line train opening scheme have been established.(5)LOGIT model has been used to solve the distribution of traffic passenger flow on the train network,which is based on the mathematical model established in the third and fourth chapters in this paper.On account of information and passenger flow data of the station,MATLAB was used to realize the algorithm and design the line train operation and stop schedule plan of high-speed railway.Finally,a comparative analysis is carried out for the calculation results of the two models.
