Study On Passenger Flow Characteristics And Safety Control Methods Of Typical Metro Stations In Guangzhou

In recent years,the urban metro has developed rapidly and become an important part of urban public transportation due to its advantages of large traffic volume,punctuality and high efficiency.As a distribution center for metro passengers,the metro station is an extremely important part of the subway system.Most of metro stations are located underground in the city,the structure is complicated and the space is limited.The congestion and queuing situation in metro stations are serious during normal operation peak hours or periods of sudden large passenger flow,on the one hand,passenger safety,travel comfort and efficiency are threatened,and on the other hand,it brings great chal enges to operation management.It is of great significance to carry out scientific and effective passenger flow safety control theoretica l methods and passenger flow organization plan measures to ensure the safe and efficie nt operation of metros.This paper focuses on the safety control of passenger flow in typical stations of Guangzhou Metro.The research work and main research results are as follows:(1)Research and analyze the characteristics of typical daily passenger flow at different typical stations,and summarize and analyze the station-level and line network coordinatio n control method of metro passenger flow;(2)Aiming at the most prone to trampling safety accidents under the condition of large passenger flow,a safety risk evaluation method for trampling accidents in crowded metro stations based on extension theory is proposed.The safety risk evaluation method of trampling accidents was carried out on the Tiyuxi Road Metro Station by issuing questionnaires,on-site investigations,consulting materials,and calculating scores;(3)Based on the existing start-up conditions of the three-stage passenger flow control of the station,the study proposes to take the critical passenger flow density of the platform as the judgment criterion for the start-up of graded passenger control.The linear programming mathematical model of the metro station-level large passenger flow safety control is constructed;(4)An optimization simulation model of passenger flow organization based on social force model is established.Taking Tiyuxi Road subway station as an example,the refineme nt and improvement plan is proposed in terms of station structure,service facilities,and streamline organization,which provides a reference for the formulation of similar station passenger control plans.
