Safe and rapid evacuation of passengers from an airport to a vantage locations is critical in the aftermath of an emergency event, which includes acts of terrorism, fire, earthquakes, tornado outbreak, power outrage, or bomb threat. Based on the severity of the crisis situation it may not be enough to evacuate the passengers from the airport, but also to make a safe passage from the airport to their final or intermediate destination, which might include the passengers’ residence, train stations, bus terminals, remote parking locations, and hotels. Though researches have been done on passenger evacuation in an airport setting, but little researches has been done on the landside capacity of the airport, which includes the highway network, parking systems, mass transit access, and intersections/interchanges in the vicinity of the airport. In this proposed project a framework to model passengers’ evacuation in an airport terminal is developed. Research will model the flow of traffic not only within the airport but also predict the flow of traffic from the airport to their final or intermediate destinations.
