Stability Evaluation Method Of High-speed Railway Passing Capacity Based On Multi-agent Simulation

With the gradual formation of my country’s "eight vertical and eight horizontal" high-speed railway skeleton network,the problem of insufficient capacity of some node hubs and high-speed railway passages has begun to emerge.Domestic high-speed railways,such as the Beijing-Shanghai high-speed railway,are the backbone lines connecting the two major economic regions of Beijing-Tianjin-Hebei and the Yangtze River Delta in the east,and play a pivotal role in the entire road network.However,with the formation of the road network,the demand for passenger flow is gradually increasing,and the capacity of the Beijing-Shanghai high-speed railway has begun to fail to meet the demand for passenger flow,which has become a bottleneck for the operation of networked trains,which affects the efficiency of the entire high-speed railway network to a certain extent.Therefore,this paper proposes a multi-agent based high-speed railway carrying capacity stability evaluation method.Through the research of Beijing Shanghai high-speed railway carrying capacity stability,it verifies the availability of the multi-agent based high-speed railway carrying capacity stability evaluation method,which is conducive to improving the operation efficiency and service level of the whole network to a certain extent,And then make a positive contribution to the national economic and social development.This paper studies the Beijing-Shanghai high-speed railway’s current operation plan.Based on the current high-speed railway operation organization mode,through analyzing the influencing factors of high-speed railway passing capacity,starting from different transportation organization methods,using the method of multi-agent simulation,the high-speed railway passing Capacity stability is studied.The specific research work is as follows:(1)Analyze and summarize the current research status of railway passing capacity by domestic and foreign scholars,and the application of simulation methods in railway operation organization.(2)Summarize the basic theories such as the utilization characteristics of highspeed railway passing capacity,fixed facilities and train operation organization and other influencing factors and main calculation methods;put forward the concept of high-speed railway interval passing capacity stability,and give an evaluation of the high-speed railway interval passing capacity stability Related indicators of sex.(3)A brief comparison of several current mainstream passing capacity calculation methods,according to the research objectives of this paper,selects the applicable simulation method and simulation software,and introduces the main features and functions of Any Logic simulation software.(4)Based on anylogic and multi-agent simulation,a simulation model of highspeed railway section carrying capacity stability is established,including the creation of visual node arc road network,control controls of the model,train operation logic controls,train vehicle components and train operation logic according to given stop scheme under different operation conditions.The definition,evaluation index and simulation model of high-speed railway carrying capacity stability constitute the evaluation method of high-speed railway carrying capacity stability.(5)Take the Beijing-Shanghai High-speed Railway Nanjing South StationShanghai Hongqiao Station as an example to verify the passenger transport section,set simulation parameters,set up the control stop plan under different operating conditions to carry out simulation experiments,and organize and analyze the simulation results and data,To evaluate the stability of the passing capacity of the Beijing-Shanghai highspeed railway,and verify the usability of the evaluation method for the stability of the passing capacity of the high-speed railway based on multi-agent simulation.
