Abstract
In this study, disaster risk assessment is conducted from the viewpoint of cultural heritage disaster mitigation in historical cities to raise the capability of regional disaster mitigation in Kyoto. First, the routes connecting fire stations and cultural heritages are selected, and those which are frequently used are designated as important road sections. Next, the road passage rate at the time of disaster is calculated for each important road section. In earlier studies, a method was adopted to find the relationship between road width and the road blockage rate using the data of the Great Hanshin-Awaji Earthquake for calculation of road passage rate at the time of disaster. This study also takes the condition of buildings along the roads and the spread of fire into consideration; consequently, a more comprehensive method of calculating the road blockage rate is proposed. Lastly, vulnerable sections of road are identified based on the road passage rate calculated using the proposed method. A proposal for road network improvement to mitigate possible disaster is drafted, and the effectiveness of the proposal is examined through reliability analysis.
