Use <strong>of</strong> emergency management modeling – The EvacSim model can take into account either a<br />
warden system or emergency warning system. The actions <strong>of</strong> fire wardens during an evacuation<br />
are determined by the user. Also, the wardens can be assigned the unique action <strong>of</strong> a “room-toroom”<br />
search on their floor level. On the fire floor, wardens relay the message to “leave<br />
immediately” to the occupants. On the other levels, the wardens hold their occupants until<br />
receiving instructions from the master warden to begin evacuation (this is the phased evacuation<br />
mode). The floors, instead <strong>of</strong> wardens, can be equipped with an emergency warning system, and<br />
the occupant’s decision to evacuate will depend on his/her defined cues (such as the information<br />
broadcast over the system).<br />
Route choice <strong>of</strong> the occupants/occupant distribution – Route choice is dependent on a list <strong>of</strong><br />
information, many <strong>of</strong> it conditional to the environment, during the evacuation as well as the<br />
familiarity with the building.<br />
Limitations: According to the developer, EvacSim needs more development and a complete<br />
validation. The model is not presently modeling some behavior related to residences, and he<br />
would like to integrate a fire model.<br />
