This paper introduces TIGS(Touring Information Guidance System) which provides information with faster access time than the human service. This system is designed specifically for a traveler. This TIGS provides tourists the informations such as destination, current map information, touring courses according to schedules, and lodging information. Furthermore, this system is implemented with touch screen for the user to apply easily. The presented shortest path algorithm using duality theory is applied to schedule the touring courses to reduce the time and the cost. The used map is raster manner instead of vectorial manner to provide user convenience. If this developed system should be established in the public space such as station, airport, and bus station, the useful touring information can be provided the tourists. This system can be easily applied to different local area.
