Abstract
A GIS-based system that determines evacuation routes for specific areas requiring evacuation. Evacuation and safe areas are determined, and evacuation routes plotted, based on emergency-specific information as well as road flow and estimated time of travel for each section of road between the evacuation area and safe area. Routes, evacuation areas, and safe areas are dynamically calculated and recalculated based on additional data, either real-time, historical, or other data added to the system, to compute optimal initial routes and redirect evacuees if changes in the emergency situation occur.
