1. In a radio system for receiving traffic bulletins which include a code identifying a location to which each bulletin relates, comprisinga mobile radio receiver (1, 9, 10);
- computer means (4, 5,
6) for determining current location (34) of said receiver and for processing said traffic bulletins;
manual actuation means (8) for input of criteria for selection among bulletins received by said receiver; and
means (7, 9, 10,
11), coupled to an output of said computer means, for indicating selected bulletins to a user,the improvement whereinsaid manual actuation means has a plurality of actuation zones (15, 16, 17,
18), each of which is associated with a respective conical area or set of traffic bulletin locations (30, 31, 32,
33), extending outward from an apex (34) at said receiver location; and
said computer means is responsive to actuation of one of said actuation zones (15, 16, 17,
18) to selectively output, via said indicating means, traffic bulletins whose location code identifies a location falling within the conical area (30,31,32,33) associated with the actuation zone which was actuated.

Abstract
Traffic Condition information is settled by actuating a key (15, 16, 17, 18) of a four-way toggle switch (8) of a radio receiver in order to specify a directional quadrant. The position (34) of the radio receiver is established by the computer (5), using program comparison and identification methods, and traffic conditions information relating to the selected directional quadrants (30, 31, 32, 33) is issued via an output device (11), for example visually by a display or acoustically via loudspeakers (10) with the aid of a voice synthesizer (7).
