To research where the congestion tends to occur in evacuation, the utility of an area-wide mesh such as GIS is considered to be one of the effective methods. In this study, the stochastic evaluation method of human damage in evacuation from tsunami using area-wide mesh proposed by the authors is extended to the method which can be considered both the congestion of evacuee. The congestion is assumed to have occurred from the street blockage caused by the building damaged by the earthquake. The congestion degree is defined by the number of people per sidewalk area in each mesh. Decrement of walking speed in evacuation is expressed by the congestion degree. Moreover, using the proposed method, the variations of the number of the human damage in evacuating from the tsunami by the difference of the evacuation awareness and the congestion by the street-blockage caused by the building damage are discussed.</p> ER -
