Abstract
Hazardous events, both natural and human-made, present tremendous risks to communities throughout the world. These events typically necessitate the evacuation of local or regional populations to safe destinations or shelters and have warning times ranging from minutes to hours or even days. The size and scope of these events present a challenge to the emergency management or agency personnel who must see to the health and safety of those living or working in their jurisdiction. This study evaluated various heuristic strategies to improve evacuation of an at-risk region by using a representative traffic roadway network. Finding evacuation strategies that reduce clearance time would lead to saving lives, time, and money. For the given test network, population density, or total number of trips, has an effect on overall clearance times; as densities (trips) increase, a greater potential for improved clearance time is indicated. Six different shift strategies were evaluated, each strategy based on origin-to-de...
