Demand Analysis And Train Operation Plan Design Of High-Speed Railway Freight Transport

With the "14th Five-Year Plan" national economic and social development,China’s economic development has entered a new normal stage,the national economic structure is further optimized and adjusted,the logistics industry is developing at a high speed,the demand for rapid transportation of goods is growing rapidly,and the development of the logistics industry has entered a new normal.Under the guidance of national policies,the railroad transport industry into a new round of reform period,China’s high-speed railroad construction further accelerated,"eight vertical and eight horizontal" constantly extended,to provide support for high-speed rail freight lines;high-speed freight locomotives successfully developed for a more comprehensive development of high-speed rail freight business to create a good foundation conditions.Therefore,it is of great practical significance to explore the operation of special high-speed rail freight trains on high-speed railroads.This paper takes the railroad transportation industry as the background,and analyzes and researches from both theoretical and practical aspects.With the rapid development of China’s logistics industry,reasonable high-speed train operation mode and operation scheme can greatly meet the growing demand for fast cargo transportation and has good application prospects.In this paper,through the combing research of related literature,we study and explore the demand prediction and operation scheme design of high-speed rail freight trains from the following aspects: firstly,we comb the relevant theories of high-speed rail freight,focusing on the feasibility and necessity of the operation of high-speed rail freight trains,and analyze the market potential of high-speed rail freight trains.Secondly,according to the economic and technical characteristics of high-speed rail freight to design,by comparing the advantages and disadvantages of linear regression model,,choose the gray prediction model for freight market scale prediction,through the high-speed rail freight market share Logit model,high-speed rail freight OD distribution double constraint gravity model for the demand of high-speed rail freight for a comprehensive and systematically forecast.On this basis,according to the transport demand,the special train operation mode of high-speed rail freight is divided into two kinds of direct trains and midway operation trains,and the operation scheme is designed to build a multi-objective operation scheme model with the objective function of minimizing the false surfeit of trains,maximizing the efficiency of transport enterprises and minimizing the cost paid by cargo owners.
