Binary transmission system

A terminal for transmitting traffic information relating to a road traffic network, comprising:

• a reception device for receiving traffic information relating to segments of a road traffic network, which is sent from a traffic information control center;
• a memory for storing identities of segments represented in transmitted traffic information and for storing information which is one of to be output for this purpose and to be used for other calculations, said memory comprising a plurality of memories for storing received traffic information which has a respective coding;
• a decoding device operatively connected to the reception device and the memory so as to use either a location coordinate table or a segment table to decode segment statements which are received using the reception device and are coded either by their location or by their identity statements, the decoding being selected based on a selection information item which is likewise received, the decoding device being operative for decoding information received with more than one coding based on the coding and storing it in the plurality of memories, and further comprising means for selecting information which is processed further or displayed;
• an output device connected to the decoding device for outputting one of decoded traffic information and navigation instructions produced using the traffic information to a user of the terminal;
• a memory having a. cross-reference table which permits association of identities of segments and locations of segments;
• and
• an association apparatus which associates received identities of segments with their location based on the cross-reference table for output to a terminal user.

A traffic information control center for transmitting traffic information relating to a road traffic network, comprising:

• a first memory for a location coordinate table which contains location coordinates of road segments;
• a second memory for a segment identity table which contains for segments a respective identity statement for the segment;
• a coding devive operative to code, for traffic information which is to be sent, segments affected by the traffic information which is to be sent selectively using one of location coordinates and identify statements, and to add thereto a selection information item representing the tipe of coding;
• and
• a transmission device for sending traffic information coded by the coding device.
