摘要
以都江堰西街为实证研究对象,提出结合现状人口密度和空间分布调查,运用软件模拟与模糊控制分析的研究方法,分析疏散标识布局与历史街区疏散效率的相互关系,并识别拥堵区域及疏散出口使用率,继而能够针对性优化支路内部和拥堵区周边疏散标识,改善历史街区整体安全环境。
Evacuation direction sign is an important facility for emergency evacuation in historical district. Reasonable evacuation direction sign is a prerequisite for improving the safety of high density public population in historical district. Based on questionnaire surveys of population density and spatial distribution of Dujiangyan West Street, the paper analyzes the relationship between the evacuation sign and the evacuation efficiency of the historical district,identifies the congestion area and evacuation export rate by using simulation and fuzzy control analysis method. The simulation approach reveals that evacuation direction sign would relieve congestion of internal branch street and the surrounding congestion area, diverge the population of the evacuation population, balance the efficiency of export utilization efficiency, strengthen the evacuation zoning control in opening space and improve the security level of the historical district.
