Passenger Flow Coordinate Control Optimal Method Research At Peak Hour Of Urban Rail Transit Line

With the rapid growth of urban rail transit passenger flow volume, the transport capacity of some lines can’t meet the demand of passenger flow in the peak period. The proper passenger flow control measures must be taken to ensure the safety of operation arrangement. This paper mainly studies how to establish effective passenger flow control scheme with scientific analysis method and provides a reference for urban rail transit operation management.Firstly, this paper analyzes the reasons and influence factors of urban rail transit passenger control and summarizes some common measures. In addition, considering the passenger flow control model must be established on the basis of passenger flow characteristic and facilities capacity, thus the passenger flow characteristics, station facilities structure and passenger’s activities are analyzed as the basis of model.Secondly, basing on the above analysis, the passenger flow control model of peak period is established by linear programming, which takes minimum passenger delay during total control time interval of line, maximum section carrying capacity as the objective function and takes station capacity, section carrying capacity, transfer capacity of some key transfer station and consideration of operation management as major constraint conditions. Based on the calculation and analysis of the relevant parameters in the model, the solving method of the model is given.At last, a case study on Beijing Urban Rail Transit Line 5 is made by using control model proposed in this paper, which obtained a passenger flow control scheme accord with the actual line situation.
