Embodiment Construction

[0047] In order to describe the technical solution disclosed in the present invention in detail, further elaboration will be made below in conjunction with the accompanying drawings and specific embodiments.

[0048] The present invention builds the evacuation network of tram station evacuation routes based on the social force model, evacuation path network mining and pedestrian flow dynamic distribution model, and uses VISSIM 10.0 to evaluate and analyze the evacuation efficiency of pedestrians in urban modern tram station emergencies .

[0049] combine figure 1 and figure 2 As shown, the tram site personnel evacuation route optimization method based on evacuation network of the present invention comprises the following steps:

[0050] (1) Obtain the type of tram station when an emergency occurs;

[0051] (2) Select the site evacuation node;

[0052] (3) Construct the evacuation path according to the selected site evacuation nodes;

[0053] (4) Define the evacuation wei...

Abstract

The invention discloses a tramcar station personnel evacuation path optimization method based on an evacuation network. The method is based on a social force model reflecting anisotropism and dynamiccharacteristics in a pedestrian advancing process; constructing an evacuation path network based on the social force model; station space distribution and evacuation nodes of the tramcar are comprehensively considered; the evacuation efficiency of the station is evaluated according to the average pedestrian density, the average evacuation length, the average evacuation time and the average evacuation capability by combining historical data and instantaneous conditions of the evacuation nodes, so that the optimal evacuation path is determined. According to the method, optimized path selection can be provided for subsequent personnel evacuation in combination with the actual evacuation situation, and the evacuation capacity of each channel station under the emergency situation can be improved.

Description

technical field [0001] The invention belongs to emergency rescue path planning and design, in particular to an evacuation network-based method for optimizing the evacuation path of tram station personnel. Background technique [0002] As an important part of urban public transportation, modern trams have become the main way of travel for urban residents, and the role of tram stations as large-scale crowd gathering facilities is becoming more and more prominent. In 2018, the average daily passenger flow of modern trams was 25,300, and the daily maximum passenger flow was 48,300. When an emergency occurs, how to quickly and effectively clear and guide a large number of people in the station has become a research hotspot. [0003] At present, the technology is mostly based on the pedestrian congestion to optimize the evacuation route of the rail transit station, and the research on the rail transit is mostly aimed at the subway. Since the subway station is mostly in the form o...
