Abstract:

Urban rail transit is an important travel mode for residents. This paper focuses on the passenger flow organization at Wanjiali of Changsha Metro. The study investigates the strategies that efficiently organize the surge of in and out of the station and optimize passenger flow with existing equipment layout and under fixed building area. The goal is to provide a more comfortable travel environment, improve the entrance and exit efficiency, and reduce passenger congestions at the station. Based on the short-term and long-term passenger flow data of Wanjiali Station, this study proposes to re-arrange the entrance and exit directions and locations of ticket checking gates and stairs, and verifies the effectiveness of the proposed method using simulation software. The results show that the new arrangement can meet the practical needs and make the passenger flow organization scheme more coordinated with the station spatial layout. To a certain extent, it eliminates passenger congestions. From a comparison between the simulation results and the theoretical calculation results, it is found that the increase of pedestrian walking time increases first, then decreases and then increases again with the increase of the number of passengers in the station, which provides a theoretical basis for the prediction of pedestrian walking time in metro station.
