Vägnavigeringssystem

A road navigation system comprises a plurality of guidance information transmitter systems disposed along a route, each transmitter system generating current location information in the form of extremely-low-powered electric waves, and a guidance signal generator system for providing guidance information for the benefit of a user. The guidance signal generator system comprises a receiver unit for receiving the current location information from the guidance information transmitter system, an input unit for inputting destination information, a memory unit for storing available map information and the inputted destination information which can be prepared as route information to be traced, a data processor unit for comparing the route information with the current location information received by the receiver unit and for producing the guidance information, and an output unit for communicating the guidance information to the user. The guidance signal generator system can provide the user with accurate guidance information within a relatively small area covered by the low-powered electric waves from the transmitter system.
