Study on the Operation and Optimization of Holiday Passenger Flow of Shenyang Metro on the Basis of Queuing Theory

: By studying the passenger flow data in and out of the station of Shenyang Metro, the changes of holiday and daily passenger flow are obtained. Determine whether and how to optimize the running interval according to the load factor and the average waiting time of passengers, and provide reference for optimizing the running interval. The selection of holiday passenger flow data is explained, the proportion of the average inbound passenger flow is used as the basis for dividing the inbound passenger flow of different lines at the transfer station. The time series stationarity test is carried out and the passenger flow attraction factor of the subway station is given in order to calculate the full load rate. By using the Random number Generator in MATLAB to generate the time interval between incoming passengers, it is checked that the incoming data of subway obeys Poisson distribution, the full-load ratio of subway and the average waiting time of passengers are calculated.
