Abstract

Processing link information related to traffic and travel information, in which link information is received including a link identification value associated with a particular link, a link identifier component enabling a determination of a link system to be employed in identifying the particular link referenced by the received traffic information, and a location type information component enabling a determination of a link location type of the particular link. Based upon the received information, a link system to be used to identify the particular link is determined. In addition, the link location type and the link identification are determined.

Claims

1. An apparatus for processing traffic information, the apparatus comprising:

a receiving device configured to receive the traffic information in a Transport Protocol Expert Group (TPEG) format, the traffic information including;

a link identifier of a link;

vertex information of a vertex within the link, wherein the vertex information includes longitude and latitude information of the vertex;

a location type information identifying a link location type of the link; and

a decoding device configured to decode the traffic information.

2. The apparatus of claim 1 wherein the receiving device is configured to receive a link system identifier value.

3. The apparatus of claim 1 wherein the receiving device is configured to receive a location type identifier value.

4. The apparatus of claim 1, wherein the traffic information further includes a mode type list component identifying a transportation type.

5. The apparatus of claim 1, wherein the traffic information further includes a link descriptor component determining one of standardized link systems.

6. The apparatus of claim 1, wherein the link identifier includes a link identification value associated with the link.

7. The apparatus of claim 1, wherein the link identifier component includes a road type list component that identifies a type of a road.
