High-speed Railway Network Route Search Research And System Development

According to the starting and ending points of the high-speed railway train operation plan,choosing a feasible and reasonable train operation route for the train is a necessary link in the compilation of high-speed railway train operation diagrams,and it is also an important factor to ensure the quality of high-speed railway train operation diagram compilation.Scientifically formulating train routes can effectively link the development of high-speed railway train plans and the compilation of high-speed railway train diagrams,which is of great significance for improving the organization and management of high-speed railway transportation.This paper summarizes and analyzes the domestic and international road network modeling and path search related research results,deeply researches the high-speed railway physical network construction method and the highspeed railway train route search technology,designs the method for solving the reasonable high-speed railway path set,and develops High-speed railway train operation route management information system.The main work of the thesis is as follows:(1)Sort out and summarize the layout characteristics of the hub area under the condition of the high-speed railway network,analyze the constituent elements of the highspeed railway network,simplify and abstract each constituent element,and construct multiple edges without negative weight composed of nodes,edges and their connection relationships The directed graph,as a high-speed railway physical network model,evaluates the characteristics of the high-speed railway physical network model.(2)Summarize and summarize the concepts and definitions of high-speed railway train operation paths,expound the role of high-speed railway train operation paths in the development of train operation plans and train operation diagrams,and analyze the influencing factors of high-speed railway train operation paths.It discusses the feasibility of high-speed railway train operation routes in terms of sections and sections.On the basis of feasible routes,based on different application scenarios,analyze the rationality of different routes and summarize the characteristics of reasonable routes.(3)Based on the constructed high-speed railway physical network and path search algorithm,design and develop a high-speed railway train operation path management information system,using the Beijing-Shanghai high-speed rail as an empirical case,search for the Beijing-Shanghai high-speed rail from Beijing South* high-speed field to Shanghai Hongqiao* high-speed field Select the optimal route from the set of reasonable routes between the Beijing-Shanghai high-speed railway and the actual route from Beijing South* Expressway to Shanghai Hongqiao* Expressway to verify the practical feasibility of the system.
