A Review of Building Evacuation Models - NIST Virtual Library

Visualization capabilities: Visualization of the evacuation can be accomplished by using
AllsafePC. However, since the model considers the population as global, the developer referred
to other advanced flow models in order to visualize evacuation.
Validation studies: Attempts have been made to compare ALLSAFE with other models, such
as Simulex. The model developers consider the model to be better validated by the use of expert
judgments which are used in tabulated values (based on accepted literature on behavior and
evacuation times).
Special features:
Fire conditions affect behavior Fire scenarios are input into the evacuation from either a fire
model or from default values in ALLSAFE.
Defining groups – Yes, the model only recognizes groups.
Disabilities/slow occupant groups – This does not seem like an option.
Delays/pre-movement time – Yes, delays such as time to fire detection, time to react to the
detection, time to interpret the situation, and time to decide where to escape are modeled.
Route choice of the occupants/occupant distribution – Only one route is available to the
occupants for each node structure.
Limitations: Only one exit per node structure.
