Research On Demand Analysis And Design Of Train Operation Plan Of High-Speed Railway Express

With the overall implement of the "13th Five-Year" Economic Plan,China's economic has entered the "New Normal" period,which means the economic structure is further adjusted and the supply-side reform is carried out in various of industries.Thus,the transportation demand of light,small quality and high-valued freight is increasing rapidly as well.Meanwhile,the construction process of China's high-speed railway network is accelerating since the government has proposed the plan of "eight vertical and eight horizontal" high-speed railway network.It brings great opportunities for the railway enterprises to participate in the competition of high valued freight transportation industry and engage the high-speed railway express business.In this context,in order to provide some references for the railway enterprises to carry out high-speed railway express and serve the economic construction of the country,this article researches the design of high-speed railway express from the prospects of demand analysis and train operation plan,and takes the Yangtze River Delta High-speed railway network as a research example.The research includes the following contents in details.(1)Demand analysis of high-speed railway expressAnalyse the demand of high-speed railway express market quanlitatively.Summerize the economic and technical characteristics and business category of the high-speed railway express.Propose the methods and process of high-speed railway express demand prediction.Design the freight prediction models including combination forecasting model,double constrained gravity model,Logit model and induced gravity model to overall predict the demand of high-speed railway express.(2)High-speed railway express train operation plan designDesign two kinds of high-speed railway express trains including through train and train with loading and unloading operation.According to process of designing train operation plan,the article establishes the operation plan model with the objective functions of the needs of transportation,profits of transportation enterprises and the degree of clients' satisfaction.Then form the constraints in terms of the actual conditions.At last,design the shortest path algorithm and linear weighted method to solve the problem.(3)A case study of high-speed railway network of the Yangtze River DeltaTaking the Yangtze River Delta area as a research example,the article constructs the high-speed railway express network model.Predict the express demand.Design the high-speed express train plan on the basic of the OD flow table.
