In the case of building fire, it is considered that the building evacuation becomes more safety by means of the active direction by voice messages which address adequately the current states of fire disaster and the evacuation route based on the dynamic fire circumstances obtained by the realtime sensing system. In this paper, differently from the conventional simulation for estimating how buildings are safe or for planning safety evacuation, the effectiveness of the active direction is estimated by means of the simulation using the zone model that makes the control of evacuation flows possible. In this simulation, residents are forced to evacuate a building by the route guidance, which directs residents to safety places away from the smoky or fire places. For the first, the "danger potential" is defined for each zone and the directions of less danger zones adjacent to each zone are described by using the "direction code". And a new algorithm, which decides the most safety evacuation routes depending on the direction code matrix induced from the danger potential matrix, is proposed. Results of the simulation using this new algorithm under a few conditions, it is estimated that more safety evacuation is achieved by guiding the residents actively to safety places. Finally, the relation between contents of voice messages, one of the means to guide residents to safety places, and human behavior, the relation between speech quality and human behavior, and the advancement of the evacuation guidance system are discussed.
