Multi-Agent Base Evacuation Support System Considering Altitude

Abstract

In this paper, we propose an extension of an evacuation support system that we have previously proposed (Taga, 2018). The system suggests evacuation routes in cases of disasters. We have confirmed the usefulness of the system. When a disaster occurs, we anticipate that the current popular wireless communication based on the Internet may not be very reliable. In order to accommodate such a problem, our proposed system employs multiple mobile agents and static agents on smartphones that use a mobile ad hoc network (MANET). The proposed system collects information by mobile agents as well as diffuses information by mobile agents so that the system provides an optimal evacuation route for each user in a dynamically changing disaster environment. In simulations, our system successfully guides evacuation users to safe areas. The system, however, does not consider the altitude of the evacuation routes. Therefore, the system may not be very useful in cases of flood. When a tsunami or a flood tide occurs, low altitude location may be under water. Therefore, evacuees need to move along high altitude routes. In this paper, we also take account of the altitude information for constructing evacuation routes.
