Multiposition Joint Control in Transfer Station Considering the Nonlinear Characteristics of Passenger Flow

Abstract

Station overcrowding negatively impacts passenger safety and travel efficiency. To deal with the overcrowding in the urban rail transit transfer station, this paper proposes a novel multiposition joint control (MPJC) model. Its objective is to meet all the safety limits in key areas of the transfer station and improve passenger travel efficiency. The model makes full use of the space, with the control positions jointly set on the moving routes of passenger flow. To make better use of the capacity of the trains to improve travel efficiency, the outflows at multiple control positions are optimized considering the nonlinear characteristics of passenger flow. Simulation experiments were carried out on GuoMao Station in the Beijing subway. Extensive experimental results demonstrated that the joint control scheme with the MPJC model can increase the average travel efficiency of passengers by 3.9% and keep the numbers of passengers in key areas under safety limits, thus effectively relieving the transport pressure in the station.
