Abstract
In this paper, we propose a method which aims to let people inside a building evacuate when a disaster occurs. Especially, it is very difficult for them to evacuate safely under the situation of blackout which makes servers down. In the proposed method, passive RFID tags are put on walls of the building and each user has a mobile terminal that is battery-powered and equipped with an RFID reader. It identifies evacuation routes by passive RFID tags the user touched. The method identifies safe routes using the movement of people who have evacuated safely. Mobile terminal communication and RFID tags realize to share information of the safe routes with many evacuees.An experiment is conducted to let people evacuate in two routes in an actual building, giving about half of them mobile terminals. We have measured the increment of blood pressure and heart rate of the evacuees before and after the evacuation. In both routes, the increasing rates of the evacuees with the terminal have been smaller than those of evacuees without the terminals. It proves that the proposed method brings assurance to evacuees.
