Abstract
An adaptive evacuation system and method for providing a safety route to evacuees. Active smoke and heat detector information can be obtained from a fire panel. Routes and exits in proximity to the active detectors are assumed to be unsafe and closed for use in evacuation. Evacuation planning is accomplished with the remaining “safe” routes. The progression of fire and smoke and the time-dependent degradation of evacuation route safety associated with progression of fire and smoke can be predicted and initial classification and signaling of route safety can be performed. As the fire progresses, the initial time-dependent classifications are updated and initially safe routes are reclassified as unsafe and then evacuation directions are modified.
