EXIT89: A Foundational Evacuation Model in the High-Rise Fire Safety Landscape

Abstract

EXIT89 is a pioneering evacuation model developed for high-rise building emergencies, integrating network modeling to simulate occupant movement during crises. This short communication examines its development by Dr. Rita F. Fahy, its applications in critical case studies, and its influence on fire safety codes. The impact of EXIT89 on evacuation modeling and high-rise fire safety is considered, especially in terms of how it laid foundational groundwork for contemporary models.
