Problems solved by technology

But we should also see that there is still a lot of room for research in the analysis of crowding degree, and how to analyze the crowding degree of individual pedestrians in dense crowds in the evacuated crowd, and reflect the relationship between the degree of crowding of individual pedestrians and the evacuated crowd as much as possible. The relationship between the current evacuation research is a top priority

Abstract

The invention discloses a simulation method of crowd evacuation route planning based on pedestrian congestion analysis. The method comprises the steps of: acquiring evacuated crowd data and determining the current restrained condition of pedestrians; calculating the binding force of the pedestrians according to the current restrained state of the pedestrians; according to the pedestrian congestionconstraint, carrying out the pedestrian congestion assessment in the pedestrian area, and calculating the probability of choosing an evacuation path according to the assessment value, and providing the M evacuation paths with the highest probability to the evacuated crowd, so as to realize the simulation path planning of crowd evacuation.

Description

technical field [0001] The disclosure relates to the technical field of evacuation simulation, in particular to a simulation method for evacuation target planning based on analysis of pedestrian congestion. Background technique [0002] The statements in this section merely enhance the background related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid development of social material and spiritual civilization, large-scale gatherings held in various public places are gradually increasing. The crowds in these places often have a high density and are in an unstable state, which can easily lead to safety issues such as crowding and trampling. ACCIDENT. In addition to the unreasonable design of public buildings, the cause of the accident is that the emergency management measures in the face of emergencies are not in place, resulting in avoidable serious congestion during the evacuation process, which brought great harm to the evacua...
