Research On Calculation Method And Simulation For Carrying Capacity Of High-speed Railway Station

With the continuous improvement of China’s high-speed railway network and the increasing demand for passenger travel,the impact of line network capacity,especially station capacity,on operation is gradually emerging.Compared with general speed railway station,high speed railway station has many differences in train type,running speed,operation plan,traffic density,station operation parameters,station operation organization plan and so on.At present,the capacity of high-speed railway station is still calculated according to the classical theoretical system and method based on the utilization rate calculation method,which can not fully meet the actual demand.A mature and unified theoretical and methodological system has not yet been formed for calculating the capacity of high-speed railway stations.The simulation method is an important method and research trend for calculating the passing capacity of high-speed railway stations.Based on this,this paper establishes a simulation system of high-speed railway station throughput based on agent modeling method on the basis of studying the related theory of high-speed railway station throughput.Finally,an example of Shenzhen North Railway Station is given,and the effectiveness and limitations of the simulation system are analyzed.This paper mainly includes the following aspects:(1)Summarize the research status of high-speed railway station capacity,and summarize the development status,existing problems and future research trends from the perspective of object-based and method.(2)The basic theory of high-speed railway station capacity is analyzed.The theoretical system and calculation method of railway station capacity,the system and operation of high-speed railway station,the characteristics of high-speed railway station capacity and its influencing factors are analyzed.(3)The optimization of arrival-departure line and throat of high-speed railway station is studied.The decision-making rules affecting the use of the hair line and throat are analyzed,and a comprehensive application model of the arrival and departure line and throat capacity is proposed.The algorithm of the arrival and departure line and throat use scheme is designed,which provides a reference for the selection of the arrival and departure line and throat route in simulation.(4)Based on Agent modeling theory,the simulation model of high-speed railway station passing capacity is constructed on the basis of analyzing the function and structure of the simulation system.The simulation model mainly includes the station yard simulation model of high-speed railway and the traction calculation simulation model of EMU.In order to control the train operation in the station,the train operation control algorithm in the station is designed,including arrival and departure route selection algorithm,throat route selection algorithm and operation route preemption algorithm.(5)Taking Shenzhen North Railway Station as the simulation object and AnyLogic as the simulation platform,an example simulation system is established.The application of arrival-departure line and throat in station simulation and the validity and limitation of simulation system are analyzed,which provides a reference for the study of high-speed railway station capacity.This paper contains 56 figures,41 tables and 69 references.
