Research on Optimization of Evacuation Path Based on Fuzzy Control and Intelligent Agent Technology-With Open Block Emergency Evacuation as Example

摘要

Evacuation path has an important influence on emergency evacuation efficiency at open space, but the evacuation path based on the shortest path is not the best choice. Such environmental variables as coverage effect of 5G signal is an important basis for intelligent guiding signs to dynamically guide the stream of people for evacuation, with bigger intervention effect with a choice of evacuation path of crowd, influencing the science of planning of evacuation path. In the paper, Yulin open block of Chengdu City is taken as the object of empirical study, and layout of guiding signs is adjusted using fuzzy control and intelligent agent technology to improve distribution of the stream of evacuated people in the space, screen out the evacuation path with high pass rate, and low congestion rate. Research result shows that the effect of the evacuation signs at the existing congestion point is not obvious at all. Fuzzy control can optimize spatial distribution of the stream of evacuated people by adjusting and controlling the degree of familiarity of evacuated crowd with different exits.
