Abstract

A method of transmitting a position of a traffic information, in particular a traffic obstruction on a traffic way in digital coding messages includes using for coding and decoding of messages transmitter- and receiver- side location data banks, coding a rough position of a traffic information by referencing to the traffic way and at least one location contained in the location data bank on the traffic way, and additionally to the location, transmitting a section part between the position and the location.

Claims

1. A method of transmitting a position of a traffic information, in particular a traffic obstruction on a traffic way in digital coding messages, comprising the steps of using for coding and decoding of messages transmitter- and receiver- side location data banks;

coding a rough position of a traffic information by referencing to the traffic way and at least one location contained in the location data bank and located on the traffic way; and

additionally to the location, transmitting a section part between the position and the location.

2. A method as defined in

claim 1

;

and further comprising referring the section part to a section between the coded location and a location on the traffic way which is spaced from the coded location by a measure.

3. A method as defined in

claim 1

;

and further comprising referring the section part to a section between the coded location and a location provided on the same traffic way immediately adjoining the coded location in the data bank.

4. A method as defined in

claim 1

;

and further comprising performing during a coding in accordance with ALERT-C protocol, performing the coding of the section part in Label 15.

5. A method as defined in

claim 1

;

and further comprising during a coding in accordance with ALERT-C protocol, performing the coding of the section part in Label 12.

6. A method as defined in

claim 1

;

and further comprising transmitting by means of the section portion a position of a beginning of a traffic obstruction; and

calculating an end of the traffic obstruction from a length transmitted via Label 2.

7. A method as defined in

claim 1

;

and further comprising transmitting by means of the section part a position of a beginning of a traffic obstruction; and

calculating an end of the traffic obstruction from a transmitted event code.

8. A method as defined in

claim 1

;

and further comprising when distance data in a location data bank of a receiver are not available, obtaining the distance data from a digital map associated with the receiver.
