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. A method for identifying at least one link, comprising:

receiving link information 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;

determining, based upon the link identifier component, a link system to be used to identify the particular link;

identifying, based upon the determined link system and the link identification value, the particular link from the received link information;

determining, based upon the location type information, the link location type of the particular link; and

associating, based on identification of the particular link, the determined link location type with the particular link referenced by the link identification value.

2. The method of claim 1 wherein:

the link identifier component includes a link system identifier value, and

determining a link system to be used to identify the particular link includes comparing the link system identifier value with an entry in a link system look-up table.

3. The method of claim 1 wherein:

the location type component includes a location type identifier value, and

determining the link location type of the particular link includes comparing the location type identifier value with an entry in a location type look-up table.

4. The method of claim 1 wherein:

the link system is a reference string-based link system,

the link identification value is indicative of a reference string, and

identifying the particular link from the received link information is further based upon the reference string.

5. The method of claim 1, wherein the link information further includes a link descriptor string value associated with the particular link, and a link descriptor component, the link descriptor component enabling a determination of a link descriptor type to be employed in identifying the link descriptor.

6. The method of claim 5 further comprising:

determining, based upon the link descriptor component, a link descriptor type to be employed to identify links;

identifying, based upon the determined link descriptor type and the link descriptor string, the particular link descriptor from the received traffic information.

7. The method of claim 1 wherein:

identifying the particular link from the received link information includes comparing the link identification value with an entry in a link identification look-up table.

8. The method of claim 7, wherein the particular link is associated with a predetermined link identification value in the link identification look-up table.

9. The method of claim 7, wherein link identification value is unique to the particular link.

10. The method of claim 7, wherein identifying the particular link from the received traffic information further includes storing an entry in the link identification look-up table.

11. An apparatus for identifying information for at least one link, the apparatus comprising:

a receiving device configured to receive link information 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; and

a processing device configured to;

determine, based upon the link identifier component, a link system to be used to identify the particular link,

identify, based upon the determined link system and the link identification value, the particular link from the received link information;

determine, based upon the location type information, the link location type of the particular link; and

associate, based on identification of the particular link, the determined link location type with the particular link referenced by the link identification value.

12. The apparatus of claim 11 wherein:

the receiving device is configured to receive a link system identifier value, and

the processing device is configured to compare the link system identifier value with an entry in a link system look-up table.

13. The apparatus of claim 11 wherein:

the receiving device is configured to receive a location type identifier value, and

the processing device is configured to compare the location type identifier value with an entry in a location type look-up table.

14. The apparatus of claim 11 wherein the link system is a reference string-based link system and the link identification value is indicative of a reference string, the processing device is further configured to:

identify the particular link from the received link information based upon the reference string.

15. The apparatus of claim 11, wherein the receiving device is configured to receive a link descriptor string value associated with the particular link, and a link descriptor component, the link descriptor component enabling a determination of a link descriptor type to be employed in identifying the link descriptor.

16. The apparatus of claim 11 where in the processing device is configured to:

determine, based upon the link descriptor component, a link descriptor type to be employed to identify links; and

identify, based upon the determined link descriptor type and the link descriptor string, the particular link descriptor from the received traffic information.

17. The apparatus of claim 11 wherein the processing device is configured to compare the link identification value with an entry in a link identification look-up table.
