Passenger flow confluence walking behavior simulation method for station facility combination part

Abstract

The invention provides a passenger flow confluence walking behavior simulation method for a station facility combination part. The method comprises the steps that the layout structure, the geometric dimension and the passenger flow streamline characteristics of a station facility combination part are obtained, and the station facility combination part is divided into a channel straight-going area,a stair area, a confluence area and an exit straight-going area; a classic social force model is used to simulate the walking behaviors of the passenger flow in the passage straight-going area and the exit straight-going area; a three-dimensional social force is introduced to simulate the walking behavior of the passenger flow in the stair area; attraction is introduced, and a turning social force model is used for simulating walking behaviors of pedestrians in a confluence area. According to the method, walking parameters under different scenes are simulated and quantified, the walking stateand the facility area passing rate are constructed to serve as indexes of bottleneck recognition through the relation between time and the layout structure and the geometrical attribute of a channel,and improvement suggestions are provided for confluence area passenger flow motion optimization and facility combination part design.

Description

Technical field [0001] The present invention relates to the technical field of urban rail transit, in particular to a method for simulating the combined walking behavior of passenger flow at the junction of station facilities. Background technique [0002] According to the statistics of Beijing subway operation data, the daily inbound passenger flow of busy stations exceeds 250,000, and congestion in the stations has become a normal operation. There are complex pedestrian flow lines in the facility junctions, which are prone to traffic jams and cause safety hazards in subway stations. To improve the efficiency and service level of passenger flow, it is necessary to deepen and refine the travel mechanism of passenger flow at the junction of facilities. Combination behavior is an important walking behavior at the junction of facilities, and it often occurs in areas where people moving in multiple directions form a single flow through turning and merging movements. The confluence ...

Problems solved by technology

[0009] (3) Research on the mechanism of passenger flow mostly relies on field experiments to explore the impact of passenger flow status on traffic efficiency, or the impact of changes in the geometric attributes of a single facility in a subway station on service levels, and less attention is paid to the junction of facilities. There is a lack of research on the influence of the geometric properties of facilities, the way of confluence and the coupling effect of channel structure on the mechanism of passenger flow.

[0010] (4) At present, when considering the influence of geometric characteristics such as aisle width and merging angle on the mechanism of passenger flow, there are few scenarios set up, and most of the conclusions obtained are qualitative conclusions

It is not yet clear whether there is a quantitative relationship between the geometric properties of the facility and the running parameters
