Effect of Disruptions on Megaregion Emergency Evacuation: A Pilot Study

The Gulf Coast region of the United States is increasingly vulnerable to a growing list of natural and manmade hazards. Mass evacuations are a fundamental protective action for the safety of the region; however, the complexity of such evacuations makes the rapid movement of people a complex task. This study introduces a performance index that ranks the criticality of each segment during a megaregion evacuation, which is then tested using simulation. It was found that links with higher exposure and fewer alternative paths are more critical, and these links’ removal has an insignificant impact on clearance time This will help future emergency planners to identify bottlenecks during mass evacuations and make important decisions.
