摘　　要：从分析应急疏散人员的行为活动入手,根据其在疏散活动开始前的决策行为获取应急疏散人员参与到疏散活动中的时间分布;根据其在紧急疏散中表现出的理性程度以及对周围环境的熟悉距离建立应急疏散人员对避难所的选择模型,估测应急疏散人员的交通空间分布情况。以实际居民区为例,结合人员的时间和空间分布特征,运用仿真软件VISSIM模拟对应于不同理性程度和熟悉距离情况下人员的建筑物外徒步疏散过程,推断人的不同行为反应对疏散效率的影响。Based on the analysis of evacuees＇ behavior during evacuation,a temporal distribution curve of residents can be obtained according to studying decision-making behavior of pedestrians before evacuation; Rationality degree and familiar distances of evacuees are introduced to construct a model which can show how people choose their destinations as safe places,and spatial distribution is obtained according to this model. VISSIM is used to simulate evacuation processes of people in a residential district who evacuate on foot,which considers temporal distribution and spatial distribution of evacuees during evacuation.Evacuation processes are simulated with changing values of rationality degree and familiar dis- tances,and the effect of people＇s different behavior on evacuation efficiency is obtained.
