When the heavy rainfalls or typhoons occurred, many counties were unavoidable to suffer the
debris-flow and flood disasters in Taiwan. Therefore, it is urgently required to obtain and
inform the real-time disaster information to display the situation, and it is important for
people to design an effective disaster information system to assist the disaster protection and
alerting works. To plan and design a Multimedia Escape and Survival System (MESS), which
is a three-tier system composed of the mobile users, multimedia server, and disaster decision
server, and the system combines mobile communication technology. MESS combines RFID
technology, GPS, GIS and GPRS/3G to find out the 4D safety paths and roads in the disaster
areas. Mobile users use mobile devices with GPS to locate the longitude and latitude, and
transmitting these coordinates to the GIS server. According to the longitude and latitude, the
GIS will draw VR map of disaster area using GIS relevant database and show the simulated
safety way to users. The MESS can draw the points on the VR map that includes all users’
position and announces the best refuge and escape path. The reasoning engine of MESS is
used Knapsack Problem (KP) and the Adaptive Path Algorithm (APA) which consider
distance, security, traffic volume, cost, and refuges where RFID readers were installed to infer
reason the 4D safety paths and escape routes.
