Definitions
- the invention relates to a method for transmitting traffic information
- RDS-TMC transmit traffic information relating to a road traffic network from a traffic information center to a terminal, with traffic information relating to this being transmitted for each segment of the road network and the traffic information transmitted segment by segment in the terminal with a coding / decoding table there a form that is suitable for display for the terminal user can be recoded.
- this widespread method is very complex when it comes to the transmission of traffic information with regard to the amount of information to be transmitted, in particular when it comes to the transmission of traffic information that has not changed over several segments of the road network.
- the object of the present invention is to provide a method and devices which are efficient and simple and inexpensive
- the invention enables traffic information relating to several segments of a road traffic network to be transmitted with less traffic
- Traffic information to be transmitted is, in particular, states of one or more segments of the road network, such as the travel time in this segment, the average speed there, the number of vehicles, the length of the traffic jam, construction sites, ghost drivers, and weather conditions.
- the transmission according to the invention is suitable both for states that remain the same over several segments (and thus traffic information to be transmitted) as well as for traffic information relating to spatially successive segments with different states.
- the first or last of these segments, the number of segments and the state are given, for example, for the transmission of traffic information relating to a state which is continuous over a plurality of spatially successive segments of a road traffic network.
- traffic information relating to different states (average speeds, etc.) of several spatially consecutive segments of a road network it is advisable to use the first or last of these consecutive segments, the number of segments and the spatial sequence of the segments for at least one segment (expediently exactly one segment) its condition indicated.
- the need to identify each of the segments with the exception of the first or last segment is advantageously eliminated, so that the amount of information to be transmitted is considerably reduced.
- a segment table is present in the terminal (expediently in the same form as in the traffic information center).
- the successive segments in the road traffic network expediently have successive segment numbers.
- a display instruction for a (for example optically representable or acoustically referable) digital card can be stored for the segment numbers of the segments; for example, a chain of
- Segments (which in the real road network represent one or more lanes of one or more directions of a highway) represent a lane in a two-dimensional representation of the road network.
- a segment can represent a motorway section, so that when a traffic information is transmitted specifying the segment and its state, a text sequence for this segment (such as the A57 motorway between Düsseldorf and Cologne) is searched for in the segment table stored in the terminal, possibly a text sequence in addition to the state (for example "traffic jam") is selected and these are output acoustically.
- the transmission is expediently carried out by radio, in particular mobile radio. Short message transmission is particularly suitable. Broadcast transmission (cell broadcast) is possible in digital mobile radio networks.
- 1 shows a section of a road network with streets divided into several segments
- Fig. 3 essential elements of the center, the terminal and the transmission as a block diagram.
- Figure 1 shows a section of a road network with a left-to-right road, consisting of segments 1 to 4 (here, the number of a segment is also used identically as its reference number), a bottom-up road with the segments
- the traffic information in the center is coded according to the invention with a table and with an identical table in the terminal for presentation to the user (for example optically in a two-dimensional digital map of the road network or acoustically). If, for example, there is a low average speed in segments 1, 2, 3 of the road running from left to right in FIG. 1, a segment identification of one of the three segments and for this purpose a status code representing the status of the segment can be transmitted, as is common with RDS-TMC.
- segment 1 for example "1”
- the number of segments 1 to 3 designated by the transmitted traffic information ie a "3” and either a state of all segments (1 to 3) transmitted here or in the order of the segments (1 to 3) the state of a segment.
- the numbering sequence of the segments is identical for the central station and the terminal. As illustrated in FIG. 1, this is possible along the street running from left to right with increasing numbers. However, it becomes problematic at crossings, in particular crossings, as in FIG. 1 on the left.
- tables according to FIGS. 2 and / or 3 are used for decoding in the terminal (and expediently identical in the traffic control center).
- FIG. 2 there is in each case a segment to represent the sequence
- Pointer to the next segment to be regarded as the next segment in the direction of travel namely segment 1, segment 2, segment 2 segment 3, segment segment 4 etc.
- an indication representing an output to a terminal user such as "A8 - Stuttgart” etc., which can be output with traffic information relating to this segment.
- the text information provided is particularly suitable for acoustic output.
- a reference to the digital map (such as coordinates) must be provided. If, for example, status information (traffic jam) is transmitted to the segment chain segment 1, 2, 3 in the terminal of the traffic information center, segment 1, number 3 and status information "0", which is decoded with a status table, is transmitted as "traffic jam".
- FIG. 3 shows, as a block diagram, the elements of the center and the terminal as well as the transmission of information from the center to the terminal.
- the traffic information center 20 receives or generates traffic information to be transmitted, which is stored in the memory 21.
- the traffic information can in particular be based on information from stationary detectors along roads of the transport network, based on mobile detectors in vehicles in the transport network and on other sources.
- Traffic information 21 to be transmitted is encoded in the traffic information packet generation device 22 according to the invention.
- a segment table For this, a segment table
- the traffic information 21 to be transmitted relating to traffic jam in segment 1, traffic jam in segment 2 and traffic jam in segment 3, is thus coded, for example, as "1, 3, 0, end” (where 1 segment means 1, 3 means three segments and 0 average speed 0 means congestion and "end” is an end flag).
- the end flag is used here only for illustration. Other protocol-technical variants are also known to the person skilled in the art for clearly identifying the end of the message.
- This coded information is transmitted to the transmission device 33 for transmission.
- the transmission device 33 can be, for example, a mobile radio transmission device or an access to a mobile radio transmission device. After transmission by radio, in particular mobile radio, these are received in the terminal 24 by the receiver 25 and decoded by a decoding device 26.
- the decoding device uses a segment table 27 (which corresponds to the segment table 23).
- the decoded traffic information can be presented to the user. They can also be saved (36).
- Traffic information can in particular also be used to calculate an optimized route in the terminal 24 by aiming for optimal travel times or as few traffic jams as possible.
- the status (“0 0 0") of each segment (1, 2, 3) of the designated (“1 3") segment chain can also be specified individually.
- the distinction can be made by the terminal by means of a flag transmitted at the beginning or by comparing the number (here once / or three times "0") of the status information before a (binary) "end” flag with the transmitted chain segment number "3".
- the invention can be implemented as a program in the control center and in the terminal, but is not limited to this and can also be designed as an electronic circuit.
