Study On Corss-line Train Operation And Transfer Transportation Of Beijing-shanghai High-speed Railway

With the gradual formation of high-speed railway network layout in China,high-speed railway plays an increasingly important role in people’s daily life.The transportation organization of high-speed railway network is also increasingly related to the vital interests of transport enterprises and ordinary railway passengers.Beijing-Shanghai high-speed railway is the main traffic artery between the north and the south of China.It connects the two economic zones of the Bohai Rim and the Yangtze River Delta.It is a model of commercial operation of high-speed railway in China.The study of its transport organization model is not only conducive to the sustainable development of Beijing-Shanghai high-speed railway,but also plays a certain reference role in the optimization of transport organization of high-speed railway network in China.The key of transportation organization is the design of train operation plan,and train operation mode is the basis of train operation plan.Firstly,this paper analyses the present situation of Beijing-Shanghai high-speed railway transportation organization and passenger flow characteristics,and concludes that the key problem in the design of train operation mode of Beijing-Shanghai high-speed railway is the choice of cross-line passenger flow transport mode.It is proposed that the mode of cross-line passenger flow transport of Beijing-Shanghai high-speed railway should be the combination of nonstop mode and transfer mode.On this basis,this paper studies the selection model of cross-line passenger transport mode based on reasonable distance of high-speed train and generalized utility,and constructs the selection method system of cross-line passenger transport mode.Then,the key issues of the nonstop mode and transfer mode of the Beijing-Shanghai high-speed railway are studied,including the coordination method of cross-line train and skylight opening mode,the calculation method of reasonable time for cross-line train to get on and off line,the selection method of transfer node based on node importance and the method of transfer organization and train connection organization of transfer node.Finally,the paper introduces the pattern diagram to optimize the train operation plan of Beijing-Shanghai high-speed railway combined with the nonstop mode and transfer mode,summarizes the selection method of local-line and cross-line train operation lines of Beijing-Shanghai high-speed railway based on the pattern diagram,and takes West Tianjin Railway Station as an example to compile the train connection plan.
