Estimation Method On Passenger Flow In The Related Area Outside Subway Station

Subway has become the first choice to travel because of its high reliability and resistance to external environmental disturbances.The non-equilibrium of passenger flow has led to the large passenger flow at stations in the morning and evening peak.In order to ensure the operation security,the stations have taken some strategies to control the inflow passenger.At present,most current-limiting schemes rely on the density of passengers in the key areas of the station or the queue length of the platform.However,the trends of the passengers entering the station was neglected,which lead to the inadequacy in the formulation of the current-limiting scheme and the inadequate implementation.The status of passenger flow in the associated area outside the station and the arrival pattern of passengers can provide theoretical support for the flow control of the station.Therefore,this paper focuses on the arrival patterns of passengers in the associated area outside the subway station and in the associated area.The contents are as follows:Firstly,define the relative area outside the subway station,and analyze the passenger flow characteristics in the relative area.The definition of relative area is identified,and the influence factors of relative area are analyzed.According to the characteristics of passenger flow in the relative area,determine the passenger flow data acquisition and data preprocessing method to provide a good data source for the related area passenger flow estimation model.Secondly,determine the calculation method of the related area outside the station.The gradient field function between travel time and aggregate benefit is constructed,and the relative area is calculated by using the improved aggregation effect model.The relative area outside the station is the precondition of the passenger flow estimation model in the connection area outside the station,and the direct correlation area in the related area outside the station is the basis of the threshold of the passenger flow in the relation area outside the station.The subway station of bajiao amusement park is verified by an example.Finally,The passenger flow in the relative area outside the station is estimated.First,the passenger flow estimation model based on Passenger Flow Pool is established.Second,ARIMA is used to fit the input and output of the model.Based on the depth residual network algorithm,the effect of reducing the cumulative error is realized and the accuracy of the model is improved.Last but not the least,The subway station of bajiao amusement park is verified by an example.
