Research on the Evaluation of Spatial Emergency Evacuation Capability in Old Residential Areas based on Space Syntax:Taking Xianglujiao Street in Dalian City as an Example
Due to factors such as the age of construction,spatial layout,and population density,the evacuation capacity of old communities is often insufficient in emergencies.This study takes the old community of Xianglu Jiao Street in Dalian as an example,assessing its evacuation capacity from the distribution and accessibility of emergency shelters.Firstly,the actual capacity radius of emergency shelters was determined,and ArcGIS was used for buffer zone analysis to assess the rationality of shelter distribution.Then,the DepthmapX software was used to create a road network segment model,and global and local integration indices were calculated to evaluate the accessibility of shelters.Based on the analysis results,the emergency evacuation capacity of the area was evaluated,and suggestions for improvement were proposed.
