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