Smart Car Technology The TravTek navigationsystem is installed in 100 Oldsmobile Toronados, the visual part of the system is a computer monitor. Through detailed colour maps, it leads the driver through the town. The map changes all the time, cause a computer connected to a navigation-satellite, and with a magnetic compass installed, calculates the fastest or easiest way to your destination. When yellow circles appear in a particular place on the screen, it means that there is traffic jam here, or there has been an accident on the spot. The computer receives this information from the Traffic Management Centre, and it quickly points an alternative route out. b:
