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.
