The purpose of this study is to evaluate accessibility to spaces for disaster refuge considering danger of street-blockades caused by collapse of buildings on evacuation routes. To this end, a model of street-blockades is developed based on Monte-Carlo simulation of collapse of each building using Tokyo Metropolitan Government GIS in the area around Machiya Station, Arakawa Ku, Tokyo. The situation of street-blockades caused by the collapse is illustrated and accessibility to spaces for disaster refuge is evaluated in terms of possibility, allocation, distances and routes of evacuation.
