Study On Transport Organization Of Beijing-Shanghai High Speed Railway

Due to the rapid development of economy in various regions in recent years,the exchanges and contacts between different regions gradually increase,and the scope and intensity of passenger flow also increase and strengthen accordingly.The increasing passenger flow and direct passenger trains on the Beijing-shanghai line have affected the framework of the train operation diagram of the line.The transport organization mode of the connecting lines is also quite different,and the operation order of each line interferes with each other,making it inconvenient for the formulation and scheduling of the transport plan.Under such a research background,how to stabilize the core train operation of the line,reduce the transportation organization difficulty of the railway operation department and improve the passenger travel experience are urgent problems to be solved for the Beijing-shanghai high-speed railway line.At present,a large number of trains running in the same direction on the Beijing-shanghai line provide great convenience for the connection and transfer between trains.Therefore,this paper studies the immature transfer transport organization work on the Beijing-shanghai line as follows:(1)The transfer behavior of passengers is analyzed.By analyzing the characteristics of passengers’ travel,waiting behavior and queuing,the travel speed of passengers is fitted according to the data,which lays a foundation for the calculation of travel time of passengers in the transfer flow line.(2)According to the classification of transfer facilities and the layout of the facilities in the transfer hub,the capacity of transfer facilities is calculated according to the characteristics of the cross-line and side-line stations on the Beijing-shanghai line.(3)Based on the analysis of the transfer streamline,the existing problems of the transfer streamline are put forward,the streamline conflicts and bottlenecks are quantified,the transfer time is calculated,and the transfer hub is optimized with the two goals of minimizing the passenger transfer utility loss and maximizing the capacity of the transfer hub.(4)The transfer nodes on the Beijing-shanghai line are classified by cluster analysis.According to the reasonable transfer time calculated in the transfer flow line and the constraints of different connection modes on the connection time,the train connection time at the transfer node is calculated.(5)With the Tianjinxi railway station on the Beijing-shanghai line as an example to transfer to the optimization of transport organization,ability,transfer to streamline the Tianjinxi railway station transfer facility optimization calculation,put forward with the transfer platform of transport organization mode,according to the Tianjinxi station of Tianjinxi railway station to change the existing train diagrams in the plan and track the plan establishment,finally through the double objective optimization model,change to the transport organization of Tianjinxi station before and after optimization comparative evaluation.
