A Study on Accessibility to Shelters Considering Building Collapse In Case of Large Scale Earthquake

Abstract

Relief supplies are necessary for living people who have to survive in shelters. Relief supplies are transported by vehicles such as a truck and ban using on emergency roads. Roadside buildings and bridges on the emergency roads are maintained for earthquake resistance. So, emergency roads are likely to be functional even after the disaster. However, secondary roads are necessary to transport relief supplies because all of shelters are not faced emergency roads. Currently, there is no guidelines about the road between the emergency road and the shelters. In this study, the access roads between the emergency roads and the shelters were analyzed considering the building collapse which is one of road closed factors. Moreover, appropriate routes of the relief supplies were analyzed through a case study. As the result of the analysis, it is revealed the shelters which may not reach relief supplies, and indicated a counter measure for these shelters.
