Study On Passenger Flow Organization And Evacuation Of A Metro Station Based On Anylogic

In recent years,the process of urban development has been further accelerated,resulting in more serious urban traffic congestion.In order to effectively alleviate urban traffic congestion,China implements the development strategy of "public transportation first" and vigorously develops public transportation to alleviate traffic pressure and reduce traffic pollution.The rapid speed,large capacity and high punctuality of rail transit have become more and more important in the development of large and mega cities.At the same time,due to the improvement of people’s living standards in recent years,social life and activities have become more abundant,and concerts,football matches and other activities have become more frequent.The sudden large passenger flow is more and more,which brings great pressure to the operation of urban rail transit.Therefore,it is of great significance to strengthen the research on the organization and evacuation of large passenger flow in rail transit.(1)Give the definition of large passenger flow according to the research literature,so as to define the distinction of large passenger flow.The reasons and characteristics of large passenger flow are analyzed.At the same time,based on the analysis of the current situation of passenger flow,find the current law of passenger flow,analyze the characteristics of passenger flow,and then analyze the relationship between the parameters of large passenger flow.From this,the type of large passenger flow studied in this paper is determined,and the organization principles and main measures are given.At the same time,the parameters of the social force model are modified according to the current population dynamics model considering the characteristics of the population and the behavior of companions.(2)Combined with the causes and characteristics of large passenger flow,this paper analyzes the large passenger flow of a subway from multiple perspectives: specific analysis is made from the specific geographical location,surrounding facilities,and the structure of the station.Find out the factors affecting the operation organization of large passenger flow;This paper analyzes the actual situation of a station under the condition of large passenger flow from two aspects of the current system capacity and the organization and control of passenger flow,and finds out the congestion point of passenger flow.(3)While introducing Anylogic software,Java language was selected and a station structure model was combined.Environment modeling is carried out through Anylogic to simulate the operation environment of the station and the operation situation of facilities and equipment transfer channels.Thus a new pedestrian flow model is constructed.Simulate pedestrian walking,simulate passenger walking streamline.(4)Each process of passenger entering the station,leaving the station and emergency evacuation is simulated by simulating the flow line model of passenger entering the station,leaving the station and emergency evacuation.In addition,simulation software was used to simulate the normal flow of passengers entering and leaving a station,and the congestion points of the station hall floor,the platform floor of Line 2 and the platform floor of Line 3 were analyzed,so as to take more targeted measures.(5)Evacuation simulation was carried out against the background of three-level large passenger flow occurring in the station,and the evacuation time and congestion points in the evacuation process were obtained.According to the simulation results,the problems of the current passenger flow organization measures in a station are analyzed.At the same time,feasible control measures are proposed for the congestion points during evacuation.
