Research On Method And Evaluation Of Pattern Train Diagram On Jinghu High Speed Railway Line

With the increasing density of high-speed railway network in China,the newly opened high-speed railway is connected with the existing high-speed railway,That forms a complex transportation network.Under these conditions,in order to improve the service quality of railway operation and the economic benefits of transportation enterprises,It is necessary to compile a high-speed train diagram with high quality and flexibility,which can well adapt to the fluctuation of passenger flow.As a comprehensive plan of railway production department,it can realize the effective allocation of capacity resources and passenger flow resources.Among them,periodic train diagram has the advantages of high density and regular operation,and has always been the focus of the research of foreign railway transportation companies.Combined with the operation characteristics of Beijing Shanghai high speed railway and the model of cross line train transportation organization,it is not consistent with the basic national conditions of our country to adopt the full cycle operation diagram.of pattern train diagram should be optimized synthetically from the principles,ideas,mechanisms.At the same time,in order to evaluate the implementation quality of operational diagram,constructing a complete evaluation system and scientific evaluation method is also one of the key research topics in the field of transportation.In summary,the main contents of this paper include the following aspects:First of all,based on the theory of periodic train diagram,combined with the characteristics of train diagram in Japan and the theory of train diagram in China,this paper puts forward the concept of pattern train diagram.On the basis of this,the author puts forward the idea and mechanism of compiling train diagram.Process and methodology innovations.Secondly,from the point of view of time and running line,this paper studies the compiling technology of pattern train diagram,including the length of unit cycle,the layout of spare line and the method of compiling unit cycle diagram,etc.To provide technical support for the compilation of pattern train diagram for Beijing-Shanghai high-speed railway.Furthermore,after demonstrating the feasibility,with the help of the above theory and technical means,an example is given to compile the normalized train operation diagram of the Beijing-Shanghai high-speed railway,and to make a comparative analysis with the present diagram.Finally,the evaluation index system is set up from the angle of image specification,production efficiency and economic benefit,and the evaluation method is studied,which provides the theoretical basis for the evaluation of the pattern train diagram on high-speed railway.
