A Multi‐Objective, Multi‐Criteria Approach to Improve Situational Awareness in Emergency Evacuation Routing Using Mobile Phone Data

Abstract

Emergency services personnel face risks and uncertainty as they respond to natural and anthropogenic events. Their primary goal is to minimize the loss of life and property, especially in neighborhoods with high population densities, where response time is of great importance. In recent years, mobile phones have become a primary communication device during emergencies. The portability of cell phones and ease of information storage and dissemination has enabled effective implementation of cell phones by first responders and one of the most viable means of communication with the population. Using cellular location data during evacuation planning and response also provides increased awareness to emergency personnel. This article introduces a multi-objective, multi-criteria approach to determining optimum evacuation routes in an urban setting. The first objective is to calculate evacuation routes for individual cell phone locations, minimizing the time it would take for a sample population to evacuate to designated safe zones based on both distance and congestion criteria. The second objective is to maximize coverage of individual cell phone locations, using the criteria of underlying geographic features, distance and congestion. In summary, this article presents a network-based methodology for providing additional analytic support to emergency services personnel for evacuation planning.

GIS-Based Analysis of Integrated Food Distribution Network in Local Food Supply Chain

“…The effectiveness of GIS in handling, display, and manipulation of geographic and spatial information (Beni, Villeneuve, LeBlanc, & Delaquis, 2011), increases the application of ArcGIS based location analysis and modelling of VRPs which could enable to design best routes (Tavares, Zsigraova, Semiao, & Carvalho, 2009;Oxendine, Sonwalkar, & Waters, 2012). In this study, the scenario based route optimisation analyses indicated the potential for improving food delivery systems.…”

Optimal Stopping Location of a High Speed Train using GIS and Multicriteria Decision‐making

“…These last capabilities are very important in emergency situations. In Oxendine et al () a multiobjective, multicriteria approach to determine optimum evacuation routes in an urban setting was introduced. The present research uses similar criteria although without considering congestion, given the interurban character of the area under study.…”

No‐Notice Urban Evacuations: Using Crowdsourced Mobile Data to Minimize Risk

“…Evacuation route optimization has been researched for many years leading to improvements in emergency evacuations routing (ReVelle and Swain 1970;Church and Cova 2000;Kwan and Lee 2005;Alçada-Almeida et al 2009;Oxendine et al 2012). Altay and Green (2006) propose that operations research has significant applications during disaster response and call for better methods and technology to improve disaster management.…”
