Abstract

The invention discloses an urban rail transit emergency evacuation optimization method and system. The method comprises the steps that metadata influencing the urban rail transit evacuation are collected, parameter classification storage is conducted on the metadata according to the Agent object type; a simulation model of urban rail transit emergency evacuation is constructed based on the Agent modeling approach by the adoption of the above stored data; analysis is conducted on the influence of evacuation time and artificial system property in the evacuation process on the evacuation result under the situation of an emergency event according to the simulation model of urban rail transit emergency evacuation; assessment and optimization are conducted on the analysis result. The invention further discloses an urban rail transit emergency evacuation optimization system which comprises a data collecting module, a modeling and simulation unit, a dynamic control unit and a simulation result analysis module. The urban rail transit emergency evacuation optimization method and system have the advantages that the intelligent simulation model can be achieved, good expandability is achieved, visual and complete analysis of the evacuation process is achieved, the auxiliary decision-making universality is strong and the like.

Description

technical field [0001] The invention relates to a traffic evacuation optimization method and system. More specifically, it relates to an optimization method and system for urban rail transit emergency evacuation. Background technique [0002] With the development of society, the subway has become an indispensable means of transportation in people's life. But the appearance of the subway accident is constantly ringing the alarm for us. Because the building structure of the subway station is usually closed, the density of people in the narrow space is high, and the evacuation route is long and there are few exits. Once an emergency occurs, it is often caused by the imperfect evacuation plan of the station, design defects, personnel mistakes and other reasons. serious consequence. History at home and abroad shows that once a fire or other emergency occurs in the subway, it will cause huge casualties and property losses. The results are often shocking and have a great negativ...
