Research On Active Management Of Metro Station Passenger Flow Based On System Dynamics Modeling

In recent years,with the continuous development of the city,the imbalance between occupation and housing has intensified,the passenger traffic undertaken by the subway has been increasing.At the same time,since most subway stations are statically considered in the initial design,there is a lack of systematic and integral consideration in the subway station,which causes the management personnel of the subway station hard to accurately grasp the entire subway station when taking corresponding management measures.When large-scale passenger flow occurs,the lack of a reasonable system response plan may result in poor operational safety in the subway station and reduced operational efficiency in the subway station.Therefore,the integral and systematic analysis of the metro station,the establishment of the corresponding subway station simulation model,and the use of simulation models to evaluate the control scheme have important theoretical and practical significance for the passenger flow management control of the metro station.In this dissertation,based on the the micro pedestrian simulation model,the pedestrian metro boarding and disembarking model is established.Secondly,based on the system dynamics principle method and the pedestrian traffic flow theory,the system dynamics model of the metro station is established after analyzing the operation organization of the subway station.Then,this thesis input the data in the boarding and disembarking model,simulate the system dynamics of the subway station in the system dynamics module of Anylogic software,and use the traditional micro-simulation software to analyze the effectiveness of the established system dynamics model;third this thesis select an actual subway station,simulate the peak hour based on the predicted traffic volume,analyze the problem and analyze the sensitivity of each parameter in the model,determine each parameter’s influence range and action form,and propose a solution based on the sensitivity analysis result.Finally,based on the sensitivity analysis results and the simulation comparison of each control.This study puts forward new ideas for the organization of passenger flow control in subwaystations.From the whole,the system and linkages consider the operation efficiency of metro stations,which provides a theoretical and model basis for the implementation of control schemes for metro station managers.The research results show that the establishment of the system dynamics model of the metro station is feasible and effective for regulating and organizing the passenger flow of the subway station.
