Time-dependent classification and signaling of evacuation route safety
First Claim
1. An adaptive evacuation method, comprising:
- automatically generating data concerning a hazard from a plurality of hazard detectors monitoring a region of interest; and
predicting how said hazard propagates over time from a current location of said hazard in order to evaluate, classify and communicate at least one safety evacuation route to at least one evacuee, thereby providing a time-dependent classification and signaling of said at least one evacuation route.

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.

19. An adaptive evacuation system, comprising:
-
a plurality of detectors for monitoring a region of interest; a situation assessor for evaluating, predicting and classifying at least one safety route based on data obtained from said plurality of detectors; a route planner for computing at least one safety evacuation plan based on said at least one safety evacuation route; and a plurality of directional devices for communicating with a plurality of evacuees in said region based on data obtained from said route planner, thereby providing a time-dependent classification and signaling of said at least one evacuation route.
