Information Sharing by Evacuee Collaboration for Assured Evacuation under Lack of Power Supply

When a disaster occurs, it is very difficult for people inside a building to evacuate safely under lack of power supply. We propose a method to realize evacuation guide in case of power failure. In this system, passive RFID tags are put on walls of the building. Each user has a mobile terminal equipped with an RFID reader/writer. By referring to passive RFID tags which the user touched, the mobile identifies safe routes using the movement of people who have evacuated safely. The mobile terminal communication and RFID system realize collaboration of safety and dangerous routes among evacuees to share information of the routes.
