ABSTRACT
From a transportation perspective, the hazard conditions and behavioral responses they elicit are important because they inuence evacuation travel demand or the amount of people and/or vehicles that are expected to be moving during an event. Perhaps even more important than just the number of people are the temporal and spatial characteristics of this demand generation. Where evacuees leave from, when they leave these locations, where they travel to gain safe shelter, what routes they will select to undertake the travel, and even what modes of transportation they will use to make the trip all govern the ability of transportation networks and assets to adequately serve this demand in a timely manner. Key performance parameters such as travel time and clearance time; the formation and recovery of congestion; travel delay; and so on are all the direct result of how and where evacuees load themselves on a network.
