Urban Disaster Prevention Shelter Location and Evacuation Behavior Analysis

Abstract

This study proposes a simple method of analyzing the road network factors and evacuation choices of residents in case of an earthquake. Using questionnaire survey data from Shin-Hua, Tainan County Taiwan, this study uses 6 indexes to evaluate shelter safety and applies a spatial statistic model with Local Indicators of Spatial Association (LISA) as an index to the evacuation choice of residents. Firstly, factor analysis is used to find the key factors affecting shelter safety, and cluster analysis is used to classify attributes. The final results with quantified indexes are then depicted in GIS maps for urban planning.
