Mapping the evacuation vulnerability in case of natural disasters employing the space syntax

Journal Title: Revista Brasileira de Cartografia - Year 2019, Vol 71, Issue 2

Abstract

In case of Natural Disasters, one of the ways of reducing human loss during the occurrence of this phenomenon is performing an evacuation of people. The evacuation consists in removing people from their housing to a place considered safe, procedure that can be done before or during the event. This study aims to develop a methodology for mapping evacuation vulnerability in case of natural disasters. It is intended to evaluate how much vulnerable a community is to execute an evacuation. Evacuation is influenced by several factors, it was decided to select the following among all of them: the quality of individuals’ life (social vulnerability), the amount of person to be evacuated (demographic density) and the quality of routes through their integration (measured by spatial syntax).From those conditioning factors, it was created an index of evacuation vulnerability assigning values from 0 to 1, where 1 is the sector with greater vulnerability and 0 the sector with less vulnerability.The case study was made in the city of Nova Friburgo, the evacuation vulnerability, in general, follows a center-periphery pattern, where the city center presents better living conditions, low exposure and more integrated routes.
