A Method for Evaluation of Wide-area Evacuation Difficulty in Case of a Major Earthquake

Abstract

In densely built-up wooden residential areas, buildings and streets must be improved so as to safeguard against high risks, which may occur during a major earthquake. In this paper, we evaluate an improvement project in terms of the difficulty of wide-area evacuation by using a multi-agent simulation model. Results show that despite an overall decrease in the average number of people who have difficulty in evacuating, some buildings along narrow and long streets still have high risk that residents cannot evacuate to any evacuation areas.
