Quantitative Modeling of Congestion in Metro Station Based on Passenger Time Perceptions

Abstract

In the metro station, passengers’ psychological state can be affected by space congestion, slow walking speed, increasing queue length, and other factors, resulting in a time-lapse effect, which can be described as people feeling that they spend more time than the actual. To measure the effect, this paper develops congestion indexes for the walking and queuing areas in metro stations, and designs stated preference (SP) and revealed preference (RP) surveys and scene simulation experiments. Based on the survey and experiment data, we attempt to describe the psychological state and space–time perception of passengers in metro stations and propose quantitative models of congestion indexes at different service levels. Furthermore, on the basis of these models, thresholds of walking distance and waiting time can be calculated for different service levels. The results can provide a reference for real-time passenger flow monitoring and theoretical supports for metro operators to measure passenger flow status and adopt passenger flow management strategies under different conditions. Overall, this study offers promising insights into passenger flow monitoring and management, but some limitations need to be addressed in future work.

Driver–passenger guidance model for Chinese freeway service areas based on path selection and parking delay

“…However, the building layout can make the route planning process for pedestrians more difficult [19]. Teng et al constructed four waiting environments on a subway platform with different levels of congestion through a simulation experiment and conducted revealed preference (RP) surveys during four periods with different levels of congestion in the walking environment of the subway station [20]. The above authors then fitted a regression model of perceived walking time under the four levels of congestion.…”

Estimation and simulation for route choice proportion in multi-period urban rail transit control systems

“…(1) The intensity of inbound passenger flow has a greater influence on the passengers' arrival time and waiting time compared with outbound passenger flow. 18 Therefore, this paper identifies periods only based on the intensity of inbound passenger flow. ( .…”

BIM-based safety design for emergency evacuation of metro stations

“…The differences and uncertainties in the behavior and psychology of different passengers generate different walking speeds in walking facilities [61]. Hence, the results of the fitting based on the Chinese metro station case are used as the walking speeds in passageways and on stairways [16].…”
