ABSTRACT:
A radio receiver selects incoming traffic messages with respect to their validity for the approximate location of the radio receiver and includes a decoder. The radio receiver uses frequency data and coordinate data transmitted by the transmitters to determine its approximate location, and compares this approximate location to locations contained in the traffic messages. When there is conformity, a conformity signal serves to switch through the location-specific messages contained in the traffic messages to an audio output device.
