Definitions
- the invention relates to a method for transmitting traffic information relating to a road traffic network from a traffic information center to at least one terminal and devices for carrying out the method.
- Traffic information is usually transmitted wirelessly (by radio) from a traffic information center to a terminal. Because of the relatively small and expensive radio transmission capacities, compressed coding is required.
- RDS radio data system
- the object of the present invention is to provide a transmission method for traffic information which allows both a compressed transmission (with a smaller amount of information to be transmitted than in the above RDS-TMC method) and a transmission of traffic information in a form decodable by simple terminals.
- the object is solved by the subject matter of the independent claims.
- the inventive design of the transmission method or the terminals and traffic information centers using the transmission channel for this purpose allows the optional transmission of traffic information either by means of a location coordinate table, the location coordinates of traffic segments to be transmitted (and possibly additional information such as the designation of traffic segments or traffic segment sections, such as for example "A8" or "A8, exit Kunststoff-Pasing") directly representing
- the terminal can determine the type of coding of the transmitted traffic information received (i.e. whether it is by location coordinate data or by the
- the selection information is expediently specified in the form of a flag in the transmitted traffic information.
- 1 is a block diagram of a traffic information center, traffic information transmitted by it and a terminal receiving the traffic information
- 2 shows an example of a coding of streets and / or street sections by segment identities denoting segments of the street
- 3 shows a cross-referencing table with location coordinate data (which can be transmitted alone or with additional information and output without a table) and the segments belonging to it.
- FIG. 1 shows a control center 1 which comes from different information sources 2
- traffic information for example, stationary traffic detectors along the roads of the traffic network, detectors / FCD floating in vehicles in traffic, state registration offices etc.
- Terminal users are output by (for example optical or acoustic) output devices 7.
- the traffic information center 1 stores traffic information coming from different information sources 2 in a memory 8 for traffic information to be transmitted.
- the traffic information can be stored directly (in this case, if necessary, quantized into gradations representing different speed classes) or (in particular for traffic information in the form of route information) in a revised manner in the memory 8 or another memory.
- a coding device 9 With a coding device 9 are to be transmitted
- Traffic information is encoded in the memory 8 in a form suitable for transmission and transmitted to a transmission device 10.
- the transmission device 10 which transmits the traffic information 3, 4 can be any radio device. It can be a radio transmission device, in particular an RDS transmission device or an access to an RDS transmission device or a mobile radio transmission device or
- a mobile radio transmission device can transmit the information in particular via a mobile radio data channel (TCH data channel or traffic data channel) or a control channel, such as the broadcast message data channel (BCH in GSM).
- a mobile radio data channel TCH data channel or traffic data channel
- a control channel such as the broadcast message data channel (BCH in GSM).
- the receiving device 11 of the terminal 6 is either for receiving over a Radio channel (RDS-TMC channel or the like) or a mobile radio channel or both.
- RDS-TMC channel Radio channel
- the coding device 9 of the control center 1 codes traffic information to be transmitted using the segment table stored in the memory 12 or in the
- Memory 13 stored GeoCode table.
- a table stored in the memory 12 is shown by way of example in FIG. 3.
- a segment (with the numbers 1, 2, 3 ..., 1 1, 12, etc.) represents a segment of a road network.
- a segment can be a street.
- a segment can also be a section of a street. It is also possible to define a segment for one or more lanes with a common or different direction of travel of a road or a road section.
- (7) text information to be output by the terminal can be stored in a memory with segments. In FIG. 3, text (7) to be output by the terminal 6 is given as an example for each segment, such as "A9 towards north Kunststoff to Nuremberg" for the segment 12.
- a segment 12 can also belong to a plurality of location coordinate data (12345678, 12345679).
- Column 34 shows segment identity data, which can optionally also be transmitted.
- Information 4 coded with a table (in FIG. 1), namely “1-3-0 - end”, comprises selection information (first “1”), which indicates that the traffic information represents segments without specifying their location by their identity, one Indication of at least one segment represented in the traffic information (second “1” in 4), the information (possibly omitted from route information) about the average speed in these segments ("0" for speed 0 km / h or traffic jam) in any defined quantization and an end character ("end") indicating the end of the segment information.
- the traffic information 3 represents the location of segments in the traffic information by means of transmitted location coordinate data (here with additional location data).
- the transmitted traffic information 3 likewise begins with selection information which, by the leading "0" of the decoding device 15 of the terminal 6, represents in the following a description of the location of
- the selection information can be transmitted at the end of the sequence or in the middle instead of leading, as shown.
- the location coordinate data "1, 2, 3, 4, 5, 6, 7, 8" following the selection information represent, for example, 12 ° 34 'west longitude, 56 ° 58' north latitude.
- additional location information "A8, exit Pasing” is given, which can be output as text (7) in the case of very simple terminal devices 6, without prior revision or preparation with tables, and coded ("4711") and / or uncoded ("black ice”) information on the states of the affected segments.
- Coded information such as "471 1” can represent, for example, a speed of 47.1 1 km / h in the segments concerned.
- Uncoded information such as "traffic jam” or "black ice” can also be output directly in simple end devices.
- Simpler terminal devices 15 can output the transmitted location coordinate data and / or the transmitted text information without processing.
- the selection of the coding (i.e. by location coordinates or segment identities) in the control center can e.g. by querying a manual entry of an operator or e.g. when requesting a terminal from the head office for traffic information by specifying in the request.
- a cross-reference table (in the memory 14 in FIG. 1) according to FIG. 3 allows the terminal-side inference of received segment identities without being able to be identified (ie without table as a location that can be decoded) location information on locations, eg from segment 12 to 12 ° 34 'WB; 56 ° 78 'NL etc.
- Figure 2 shows an example of the coding of a road network by segments.
- the segments 1 to 11 end at intersections, exits,
- Branches etc. Branches to streets of lower classes (for example from a freeway to a country road as between segments 7 and 8) are only shown as far as relevant (i.e. in the form of the branching freeway). Instead of a segment as here, more than one segment can also be used for the different directions and / or lanes of a road section.
- the invention can be implemented in a traffic information center and in the terminal as a program or as an electronic circuit. However, it is not limited to implementation as a program.
