Metro station people emergency evacuation simulation method and system

Abstract

The invention discloses a metro station people emergency evacuation simulation method and system. The method comprises the steps of 1, building a metro station emergency evacuation simulation scene, and initializing people to be evacuated; 2, simulating perception for surroundings and mental and physiological status of the people to be evacuated; 3, according to the perception result of the surroundings and mental and physiological status of the people to be evacuated, building a social force model including the mental and physiological status of the people to be evacuated; 4, according to the social force model including the mental and physiological status of the people to be evacuated, building a motion path and motion speed decision model of the people to be evacuated; 5, performing simulating on the motion path and motion speed decision model of the people to be evacuated according to the time step method, and obtaining the motion status and the final simulation result of the people to be evacuated at each simulation moment. The emergency evacuation measure formulation and implementation reasonability and effectiveness can be improved.

Description

technical field [0001] The invention relates to the emergency evacuation of subway station personnel. More specifically, it relates to a simulation method and system for emergency evacuation of subway station personnel. Background technique [0002] During the period of rapid development of the urban rail transit system, ensuring the safety of passengers has become the focus of attention of the whole society. Most subway stations are built underground and have a high degree of closure. When a high-intensity passenger flow or an emergency occurs, ensuring that all passengers are transferred to a safe location within the specified time and reducing the probability of secondary accidents has become the research focus of relevant departments, experts and scholars. There are a large number of passengers and staff in the subway system, and different personnel have different psychological acceptance and responses to emergency evacuation. The relevant conclusions obtained by usin...

AI Technical Summary

Problems solved by technology

Although the above methods can accurately describe the general state of evacuation, there are the following problems: (1) In the face of emergencies, the evacuees, as independent individuals, have different physiological and psychological states, so targeted individual research and There are few studies on the connection between personnel's physiology and psychology; (2) The comprehensive consideration of the impact of various influencing factors on personnel's psychology, especially the research on the panic feelings of personnel themselves and the spread of panic among groups is relatively few; (3) There are few studies on the change of personnel movement state due to the decrease of effective visibility of personnel caused by subway fires and smoke; (4) Most of the current personnel evacuation simulation work is based on existing simulation software. The pertinence is not strong, the secondary development support for the underlying model and actual parameters is poor, and it cannot flexibly adapt to changes in actual problems and research scenarios during use

Although the current models for evacuation simulation of personnel movement are relatively mature, there are few models considering the psychological and physiological interaction in the process of personnel movement, and there are few studies considering the interaction between personnel and the surrounding environment.
