This includes construction site information, weather information, information about traffic disruptions or the like. , the information touching national and international main routes, regional routes as well as local and rural routes.
- the traffic information can be kept smaller, which leads to a shorter transmission time, lower transmission costs and easier processing of the traffic information.
- a first increase sign and / or a second increase sign can occur within an information block.
- Increase signs are used to precisely characterize the extent of a traffic disruption. For navigation purposes in particular, it is important to supply precise information about the extent of traffic disturbances to a navigation unit.
- Other possible components of a traffic disruption For navigation purposes in particular, it is important to supply precise information about the extent of traffic disturbances to a navigation unit.
- a single event option only provides second length information. Other possible components of an individual event option are therefore not provided in the subset for coding traffic information. This contributes to simplifying the coding and decoding process.
- Multiple use option provides an optional event.
- Event can be broadcast. It is also advantageous that a for each optional event
- Information block is transferable. Another advantage is that location information, which is provided in the information portion of the traffic information coded according to the subset, is present in coded form according to a location table. As a result, location information that is transmitted in the information section is not permitted in the form of EUROAD location information, which leads to a simpler structure of the traffic information.

- the receiver according to the invention has a navigation unit which comprises means for processing the information content of traffic reports. This enables a navigation task through the use of traffic information after the
- Subset of the specified regulations are coded, faster and easier to carry out.
- the transmitter prefferably has a transmission unit, signals which comprise coded traffic information being able to be transmitted by the transmission unit.

- Traffic information can then be received by a mobile receiver via a public or private communication channel.
- the transmitter has a receiving unit, wherein the receiving unit can receive signals that include information requests and / or coded traffic information.
- a receiving unit enables the transmitter to receive information from one or more receivers and thereby To send traffic information specifically to certain recipients or to allow certain recipients to receive a specific selection of traffic information.
- the transmitter comprises a TMC coder, traffic information encoded according to the subset being encodable by means of the TMC coder. This allows traffic information encoded according to the subset to be sent to one or more recipients. An agreement to broadcast exclusively from
- Traffic information encoded according to the subset is advantageous. Because the receiver only receives traffic information that is coded according to the subset, it can be designed in a simpler and thus more cost-effective manner. In addition, this leads to a simpler transmission mode in the transmitter because the traffic information is small according to the invention.

- the information option 440 is shown in FIG. It consists of either simple group information (SingleGroupOptions) or one or more information blocks (500) (InfoBlock). If the information options include 440 multiple group options, for example according to the RDS-TMC standard, then the multiple group options are composed of information blocks 500. In the following, an information option 440 either consists of individual group options or one or more information blocks 500. According to the invention, the information options 440 consist of exactly one information block 500.
- the simple group options can include diversion information 480 (DiversionBit) and fault duration information 490 (DurationCode).

- the location information 430 comprises a first location 450, a dimension information 460 and a direction information 470.
- the first location 450 can either be based on a location code (LocationCode) using a location table or by means of a EUROAD location (EUROAD location).
- the first location 450 is described exclusively by means of the location code and the location table, as a result of which the method is simplified in particular in the decoding, coding and error handling.
- the extent information 460 and the direction information 470 are also used in the subset of the ALERT-C syntax according to the invention in accordance with the regulations of the ALERT-C syntax.
- the information options 440 comprise either the simple group options or one or more information blocks 500.

- Traffic information 410 consists of at least three groups according to the RDS-TMC standard. This is to be avoided with the method according to the invention. According to the invention, the number of groups of traffic information 410 should be a maximum of two. Hence the
- Information options 440 according to the invention thus consist of only one information block 500 or of simple group options.
- an information block 500 can consist of individual information options 510, multiple use options 520 or individual event options 530.
- an individual information option 510 can only contain a first increase sign 540 and / or a second increase sign 550.
- a multiple use option 520 can only provide one optional event (OptEvent).
