Research On Passenger Flow Control Method Of Metro Station In Peak Period Based On Simulation

With the development of urbanization,people in China are moving into city,leads to a continuously increasing of urban population and the demand of urban rail transit.While the limited capacity of some rail transit lines due to the planning background,resulting in the contradiction between passenger flow demand and equipment capacity in urban rail transit system.Operators need to develop an effective passenger flow control scheme to ensure the urban rail transit system function safely and orderly and exert the maximum transportation capacity under the existing hardware conditions.This paper summarizes the experience of existing passenger flow control methods,expounds the basic principles of station level passenger flow control,and lists the common control methods in some domestic cities.Then,the methods and measures of passenger flow control in the station are simulated by using Anylogic traffic flow software,including organizing passengers to bypass,controlling the number of gate opening,etc.The effect evaluation of each measure will be analyzed as well.Through the simulation,it is found that:(1)Organizing the passenger station to bypass and adjusting the number of gates has a good control effect on the speed of passengers entering the station;(2)Adjusting and optimizing the streamline in the station can improve the capacity of station equipment;(3)Adjusting the direction of entrances and exits or redistribution to balance the passenger amount of each entrances can reduce the waiting time of passengers.According to these results above,a set of passenger flow control scheme formulation process is summarized.Taking Zhujiang New Town Station of Guangzhou Metro as an example,a reasonable passenger flow control scheme in late peak period is formulated according to the actual situation of the station.Then the scheme will be simulated by using Anylogic,and the passenger flow control effect is verified by comparing various indicators before and after taking passenger control measures.The results show that the passenger flow control scheme can solve the problem of insufficient capacity of station transfer nodes,relieve the passenger flow pressure of station platform during peak hours,and ensure the safe operation of the station.Besides,passenger throughput of the station has improved,and train capacity can be more fully utilized.
