Abstract
This 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.
Highlights
Building type and structure of the city is considered as one of the influential factors in decreasing vulnerability among the cities, especially damages due to earthquake
A decrease in vulnerability against earthquake among urban communities occurred when the safety was considered in all planning levels, among which determining and optimizing relief and emergency evacuation roads is considered as one of the issues which can play a significant role in decreasing the casualties and damage rate if implemented (Ganjehi et al 2013, 2014, 2017)
Stage A: In this stage, after studying the documents available in the libraries, analyzing the retrieved data, and considering the results derived from the review of literature, a questionnaire was developed based on Analytic Hierarchy Process (AHP) model and distributed among the 23 experts in order to extract the effective parameters in determining the optimal roads
Summary
Building type and structure of the city is considered as one of the influential factors in decreasing vulnerability among the cities, especially damages due to earthquake. Considering capacity building in urban crisis management, determining and optimizing relief and emergency evacuation roads after disasters, as well as finding the safest emergency accommodation are really important.
