Emergency Evacuation Mechanism and Sign Optimization Design of Old Residential Areas Using Simulation Technology:Taking Shenzhen as an Example
With the impact of extreme weather conditions,the vulnerable nature of old residential areas is increasingly exposed,necessitating urgent solutions to evacuation issues.The existing regulations provide limited guidance on emergency evacuation signage for such buildings.This paper takes Shenzhen's old residential area as a prototype,summarizes evacuation challenges,and categorizes the evacuation system into two kinds of basic road network structure:fishbone type and inner ring type.Utilizing Pathfinder software,this paper classifies the evacuation mechanism,gather relevant data indicators for evacuations,identify congested areas during the process,and evaluate evacuation efficiency.By altering personnel evacuation routes to enhance efficiency in terms of total evacuation time and alleviating road congestion as optimization objectives,an optimal emergency evacuation plan is formulated.Furthermore,by guiding sign layout in old residential areas and optimizing sign plate information designations,an optimal strategy for emergency evacuation signs in these areas is ultimately established to contribute towards enhancing their security.
