Abstract

In this study, we examined the implications of critical road segment failures on the timely evacuation of Borongan City residents, specifically focusing on the elderly demographics who face unique mobility challenges during emergencies. Building upon our prior work (Pabico, 2024), which utilized isochrone mapping to analyze accessibility, we broaden our approach to examine the impact of critical road segment failures on access to evacuation centers during disaster scenarios. By utilizing network analysis, we simulated potential road segment disruptions to determine the increased evacuation times for affected populations. Our criticality assessment identified those road segments whose failures would lead to significant delays, emphasizing their influence on evacuation efficiency for elderly residents, who represent the slowest-moving demographic and are therefore highly vulnerable in emergencies. Through this analysis, we not only highlight potential bottlenecks but also propose actionable insights for targeted disaster risk reduction strategies, including alternate route planning and prioritization of road maintenance in critical areas. Our findings underscore the need for integrative disaster risk reduction and management planning in Borongan City. We aim to provide local governments and emergency planners with evidence-based recommendations for improving evacuation infrastructure, optimizing emergency response protocols, and enhancing overall community resilience. Ultimately, we advocate for prioritizing vulnerable populations in evacuation planning to ensure that all residents, particularly the elderly, have timely access to safe evacuation centers during disasters.
