Abstract:
An adaptive escape routing system comprising:a plurality of sensors for sensing the occurrence of a hazardous event within a building or occupied structure, the building or occupied structure having a plurality of emergency exits and signage associated therewith; and a controller connected to the sensors for determining a subset of the exits providing a safe exit route in the event of a hazardous event, the controller, upon receiving information from one or more sensors indicating a hazardous event, accessing a memory as a function of the sensor or sensors indicating the hazardous event and determining a probable dispersal pattern for some period of time after the hazardous event is initially sensed and identifying that subset of exits providing a safe exit route as a function of the probable dispersal pattern, the controller controlling the signage to direct occupants to the subset of exits providing a safe exit route.
