Determination of emergency roads to emergency accommodation using loss analysis results

Abstract

AbstractThis study presents a method to identify safe places to build temporary accommodation and accessible relief routes using the results of damage analysis for an earthquake within the bounds of probability for the city of Shiraz in Iran. The commonly used HAZUS damage estimation method was used. The most influential factors on the location of safe temporary accommodation in Shiraz were determined by use of the damage results, the Analytic Hierarchy Process (AHP) model, and Expert Choice software. A map for the resulting optimal locations of temporary accommodation was prepared. Subsequently, all of the parameters influencing the safety of emergency evacuation efforts and the relief network were identified and the impact rate of each one was determined based on expert opinions through AHP. Based on the resultant importance of each index, roads were weighted and coded. The optimally safe routes for relief and emergency evacuation were determined. The results suggested that different indices suggest different relief routes and the optimal route was obtained through overlapping the data layers according to the importance of each parameter. This optimal route could provide maximum services in the minimum time and subsequently create capacity building in urban crisis management.
