The origin and basic features of EXIT89 have been
described in previous papers. This paper will
concentrate on a brief discussion of the framework of
the model, a description of recent enhancements made to
the model and will present example applications of the
model that illustrate some of its features. EXIT89 was
designed to model the evacuation of a large building
with the capability of tracking each occupant
individually. The output of this model, in combination
with a fire and smoke movement model using the same
building layout, can be used to predict the effects of
cumulative exposure to the toxic environment present in
a structure fire.
