Abstract:This study proposed, implemented, tested, and demonstrated an emergency evacuation modeling framework called T-REX, or Tennessee Rapid Evacuation micro-simulation. The purpose of the effort is to provide a simple workflow for the implementation in smaller isolated communities or tourist attractions where we often observe 1) captive transportation network options and exit capacity, 2) significant number of visitors unfamiliar with local hazards or evacuation options, and 3) limited resources for planning, modeling, or executing complex evacuation operations. Five case studies were conducted for Gatlinburg, Manchester, Downtown Nashville, Lynchburg, and Wears Valley area of Tennessee. More in depth presentation and discussion on the results of the fifth site at Wears Valley was documented in Chapter 4 because it was the most recent occurrence and because the team was able to obtain detailed feedback from local EMA personnel. Key findings of the study include 1) the demonstrated timely and rapid implementation of T-REX framework for modeling a handful sites in the state of Tennessee; 2) the economical implementation of the framework because each component was off-the-shelf, tested, and essentially free to use by the public; 3) the framework has the flexibility to be implemented by different agencies with past experience or current preference if different simulation software, population data, or transportation network were to be employed; and 4) the results from T-REX process are to be compared relatively and interpreted carefully by researchers and practitioners to provide insightful recommendations to decision-makers. This study also looked into future implementation means for benefiting other sites in and around the State of Tennessee. The funding vehicles of LTAP and UTAP are suitable for engaging university researchers to help local jurisdictions.
