Emergency evacuationTraining and policy decisions are difficult
Scenario: Evacuation of an airport terminal after an event
Ideal: Conduct live exercises Personnel can see what actually happens
Policy-makers can try different rules
Issue: Live exercises are difficult Requires the terminal to be shut down
Requires realistic response of hundreds of people
Unethical to instill real fear/anxiety in people

Evacuation simulationSimulations provide an answer
Proposal: Simulation replaces live exercises Evaluate different policies
Decision-making training for officer
Visual conditioning for officers
We propose to build an agent-based model with realistic human behavior and compelling visualization

Our approachWe focus on unaddressed issues unique to the domain
BDI-style architecture Standard architecture style for agents
Social Comparison Theory mechanics General theory of how agents impact each other
Transition to emergency Model the transition from normal to emergency behavior
Massive software visualization Movie-quality people seen at eye-level

Previous work: TeamcoreWe have worked in simulations in the past
DEFACTO system Training / coordination tool for fire
department incident commanders
Robocup Rescue Search and rescue simulation
Helicopter team simulations Helicopter attack strategy simulation

Previous work: Academic Evac. SimulationWealth of work in evacuation simulations
BDI-style architecture Agent interactivity without underlying social theory
Social Psychology simulations Apply theories limited to very specific activities
Physics-based simulations Individual behaviors are generalized
We propose to use a general psychological model that can model both ‘normal’ and ‘emergency’ behavior

Previous work: Architectural planningArchitectural simulations provide a high-level view
Metrics are high-level (e.g., time to clear a building)
Lacks validated realism in individual behavior

Previous work: CinemaCinema simulations focus on dramatic effect and believability
Metrics involve believability, director’s desires, etc.
