Abstract

In this paper we present an agent-based evacuation model which may be used to support private sector organizations withcapabilities-based planning efforts surrounding likely terrorist attack scenarios. The model is distinguished by its explicitconsideration of individuals with disabilities in respect to the characteristics influencing their ability to negotiatesurroundings. The virtual environment is also classified according to several accessibility traits shown to have adisproportionate effect upon behavior during an emergency. The results of an experiment simulating the truck bombing of anintermountain west sports arena reveal special areas of concern for arena managers and identify those who are most at risk orindividuals with lower stamina. Ultimately, the model can be used to inform policy makers of more effective, evidence-basedevacuation planning methods based on a better understanding of the behavior of heterogeneous populations duringemergency situations.
