Abstract

A methodology was proposed to rank paths in road networks considering various attributes to facilitate equitable improvement in connectivity to essential service facilities during or after disaster events. Existing methods do not typically rank paths and are insufficient for specific applications like assessing accessibility to hospitals during hazards for minority populations. The proposed method first ranked links on multiple attributes using a non-dominated sorting algorithm. Then, paths are ranked based on the importance of links in them. The proposed method was applied to a case study region in southern Louisiana to rank paths that can be improved to equitably improve access to essential service facilities during hurricane-induced flooding. For this purpose, attributes like population, the likelihood of links flooding, the topological importance of links, and the population of disproportionately affected groups were considered. Results highlighted that the most beneficial strategies prioritized enhancing connectivity for the Native American demographic.
