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, and the disaster decision is packed as a reusable
web services which can be used in MESS or other systems for
reducing the cost and speeding up the efficiency of system
development in the future. 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
