As buildings become taller and more complex, establishing clear evacuation routes becomes very important in the event of a fire or other emergency. In this paper, Wireless Sensor Networks (WSN), Radio Frequency Identification (RFID) and real time escape route guidance are integrated to accomplish a real-time fire evacuation system to guide along an evacuation route. When the emergency event occurs, the system provides evacuation route guidance to people for them to be able to avoid danger. Moreover, in the proposed system, an intelligent evacuation route is provided by indicating in digital signage the best evacuation route as well as pertinent information to improve the chances of survival for users. The proposed system also supplies real time environmental information to fire fighters assuring better efficiency in their rescue operations.

Nowadays, in case of an emergency, and because of the more complicated interiors of buildings, people may not be able to easily find a safe escape route within limited time. An immediately available evacuation guide can improve safety in public buildings. In this research paper, we propose an intelligent guidance system that is a combination of image recognition and Digital Signage for conducting people to safety. This system applies WSN and RFID to collect environmental information, IP cameras to monitor group movements and uses an evaluation algorithm to circulate a safe route using environmental information obtained from the system and then smartphones and digital signage to guide people to the exit. Instruction guides are displayed using the digital signage. The execution time of the proposed system was also evaluated: the overall processing time for a complex space was less than 1.1 second showing the superior efficiency of the proposed system compared with previous systems.
