Study On The Optimization Of Train Operation Plan For Intercity Railway

In the construction of the city circle,the inter-city railway plays an important role,which is an important means to realize the sharing of resources,improve the efficiency of the rail transit operation,alleviate the urban traffic congestion and expand the influence of the central city.The optimization strategy of intercity railway operation plan based on passenger demand is helpful to enhance the attractiveness of inter-city railway traffic,alleviate the congestion of ground traffic and make a good development environment and regional economic development for the travel of urban residents.However,the theory and practice of intercity railway operation in our country are still in the preliminary exploration stage.There is not enough research on how to develop and optimize the operation plan of intercity railway under intercity railway operation.Based on this,Optimization of the study,the main research as follows:Firstly,through introducing the background and significance of the intercity railway,and on the basis of consulting a large number of literatures,summarize the research situation of the intercity railway at home and abroad,and find that the intercity train running scheme is different from the traditional operation scheme.The operation plan should be more in line with the passenger travel demand conclusion.Then the optimization method,principle and process of intercity railway train operation are analyzed.Secondly,the influence factors of intercity railway train operation plan are analyzed.The factors such as traffic volume,economic benefit and station traffic capacity are analyzed emphatically.The formula and method of traffic flow and station traffic are given.Finally,based on the classification of passengers and the definition of passenger retention rate,this paper establishes the dynamic allocation model of intercity passenger dedicated passenger train in different grades,and builds the target equation and the constraint equation to form the train operation plan optimization model on the basis of the passenger flow dynamic distribution model.At last,taking the Guangqing Intercity Railway as an example,using the optimization model of running scheme to generate series running time and train grade,the validity of the optimization model is proved.
