Abstract
EXIT89 was designed to model the evacuation of a large building while tracking the travel paths of each individual occupant. In combination with a fire and smoke movement model, EXIT89 can be used to predict the effects of fire spread on evacuation. Used alone, it can provide a best-case evacuation time estimate. The model has been enhanced to allow the user to specify occupants' travel paths, to delay the beginning of evacuation by location or randomly among all occupants and to simulate the presence of disabled occupants. A beta test version of the model will be distributed by the end of 1995 and plans are to include this model in a future version of HAZARD I. This paper describes recent enhancements in more detail and includes examples that demonstrate the use of those new features.
