A well-designed system for evacuations after warning issues is essentially necessary to reduce human loss. A lack of tools to evaluate an evacuation system lets such problem remain for long time. The objective of the present study is to develop the evacuation model simulating the behavior of human and vehicle by using the network model in the case of a tsunami attack. One of important functions in a model is to include route self-selecting/alternative model at several crossings by interacting and compiling human behaviors and tsunami impact, road condition, and people recognition of geometry. And walking and vehicle speed with function of density and condition on a road should be also included into a model. The three kinds of field studies were carried out ; (1) determination of route self-selecting/alternative at the area, (2) human behaviors of individuals and group on a beach, and (3) evacuation drill to know the human behavior and judgment. The results from these studies are includ … More ed into the model. The validity of the model is examined in the case of the 1993 Hokkaidonansei-oki tsunami at the Aonae area, Okushiri, Hokkaido. The number of survivors and casualties estimated by the model shows good agreement with the reported and the main routes for evacuation to the hill simulated by the model are same as those by the eyewitness accounts. Another aim of the present study is, therefore, to develop the model to estimate the starting time of evacuation at several stages by using the quantification method like multi-variable analysis. The parameters in the model, called a category scores, could be determined by the data on the tsunami evacuations in the past. Provided the earthquake intensity, location, experiences and time zone at each region, the ratio of the evacuation and its starting time can be estimated and be compared with the tsunami arrival time, which is useful to evaluate the present system against the tsunami attack. We applied the model to Miyagi prefecture along the coast and discuss the risk of the tsunamiattacks. Less

一个设计良好的警报发布后疏散系统对于减少人员损失至关重要。由于缺乏评估疏散系统的工具，这一问题长期存在。本研究的目的是发展疏散模型，模拟在海啸袭击的情况下，通过使用网络模型的人和车辆的行为。模型的重要功能之一是通过交互和编译人类行为和海啸影响、道路状况以及人们对几何形状的识别，在多个交叉口处包括路线自选择/替代模型。模型中还应考虑步行速度和车速与道路密度和路况的函数关系。进行了三种实地研究：（1）确定该地区的路线自我选择/替代方案，（2）海滩上的个人和群体的行为，（3）疏散演习，以了解人类的行为和判断。包括这些研究的结果 ...更多信息 艾德进入模型。该模型的有效性进行了检查的情况下，1993年Hokkaidonansei-oki海啸在青苗地区，奥走，北海道。模型计算的伤亡人数与实际报道吻合较好，疏散上山的主要路线与现场目击者的描述一致。因此，本研究的另一个目的是建立一个模型，通过使用多变量分析等量化方法来估计疏散的开始时间。模型中的参数，称为类别分数，可以通过过去海啸疏散的数据来确定。根据地震烈度、地震位置、地震经验和地震发生时间，可以计算出海啸发生后人员疏散的时间与海啸发生时间的比值，并与海啸到达时间进行比较，为评估现有系统抵御海啸袭击的能力提供参考。我们应用该模型的宫城县沿着海岸，并讨论了海啸袭击的风险。少
