A Study On Evaluation Methods For Safety Risks Of Large Passenger Flow On Metro Transfer Stations

By the end of 2019,the daily average passenger capacity of the total operation lines of Shanghai rail transit has exceeded 10 million,and the operation scale has leaped to the first place in the world.Shanghai rail transit has entered the stage of network formation,and the safety risk of transfer stations under the condition of super large scale road network is increasing day by day,so it is necessary to pay attention to the safety risk assessment of transfer stations.Based on the analysis of the pressure of the different safety risk parts of the micro passenger flow in the interchange station,this paper builds the pressure model of the different risk parts,sorts the safety risk evaluation grades of the different parts with the analytic hierarchy process,and forecasts the passenger flow values of the different types and different periods of the interchange station by using the BP neural network Evaluate the matrix to identify the safety risk level of transfer station.Finally,taking Hanzhong Road station as an example,through Sta Pass simulation software,the passenger flow distribution characteristics of Hanzhong Road station are drawn,and a series of passenger flow control rules are set up,such as adjusting current limiting railings,increasing personnel and other safety control methods,to check the method of reducing passenger flow safety risk,forming a relatively complete set of theoretical research and practical application of the safety risk of transfer station evaluation methods.
