Abstract

A method of facilitating delivery of traffic messages is disclosed. Data indicating a plurality of traffic conditions on a road network are obtained. For each of the traffic conditions, the data provides a location description. For each of the traffic conditions, the location description is converted into a location reference code assigned by a traffic message supplier. A plurality of traffic messages representing the traffic conditions is transmitted. Each of the traffic messages includes the location reference code of the traffic condition.

Claims

1. A method for developing a plurality of traffic messages using a computing platform, said method comprising:

obtaining a start location description and an end location description for a traffic condition on a road network;

determining an extent of said traffic condition by comparing said end location description to said start location description, wherein said extent is greater than a single road segment of the road network;

converting said start location description into a start point location reference code, wherein said start point location reference code specifies a predefined point location on said road network;

determining a number of adjacent point locations downstream from a location associated with said start point location reference code affected by said extent of said traffic condition; and

providing said traffic message representing said traffic condition, said traffic message includes said start point location reference code and information regarding said number of adjacent point locations.

2. The method of claim 1 wherein said start location description includes a text description.

3. The method of claim 1 wherein said start location description includes a point of interest.

4. The method of claim 1 wherein said start location description includes an address.

5. The method of claim 1 wherein said start location description includes a road name.

6. The method of claim 1 wherein said start location description includes a latitude and longitude position.

7. A method for developing a plurality of traffic messages using a computing platform, said method comprising:

obtaining a start location description, an end location description and an event description for a traffic condition on a road network;

determining a direction on the road network affected by said traffic condition by comparing said end location description to said start location description;

converting said start location description into a start point location reference code and said event description into an event code assigned by a traffic message supplier, wherein said start point location reference code specifies a predefined point location on said road network; and

providing said traffic message representing said traffic condition, said traffic message includes said start point location reference code, said event code and information regarding said direction.

8. The method of claim 7 wherein said event description is a traffic speed.

9. The method of claim 7 wherein said event description is an accident.

10. The method of claim 7 wherein said event description is construction information.

11. A method for developing a plurality of traffic messages using a computing platform, said method comprising:

obtaining a start location description and an end location description for a traffic condition on a road network;

determining a direction on the road network affected by said traffic condition by comparing said end location description to said start location description;

determining an extent of said traffic condition by comparing said end location description to said start location description, wherein said extent is greater than a single road segment of the road network;

formatting said start location description into a traffic location code, wherein said traffic location code includes a traffic location table identification code specifying one of a plurality of traffic location tables and a point location identification code specifying a predefined point location on said road network; and

transmitting said traffic message representing said traffic condition for broadcast to a plurality of end user computing platforms having said plurality of traffic location tables, said traffic message includes said traffic location code corresponding to said traffic condition and information regarding said direction and said extent of said traffic condition.

12. The method of claim 11, wherein said start location description includes a text description.

13. The method of claim 11 wherein said start location description includes a landmark.

14. The method of claim 11 wherein said start location description includes a point of interest.

15. The method of claim 11 wherein said start location description includes an address.

16. The method of claim 11 wherein said start location description includes a latitude and longitude position.

17. The method of claim 11 wherein said start location description includes a road name.

18. The method of claim 11 wherein said start location description includes a road name on which said traffic condition exists and a first cross road name proximate said start location and said end location description includes a second cross road name proximate said end location of said traffic condition.

19. The method of claim 11 wherein said formatting step comprises geo-coding said start location description with a geographic database.

20. The method of claim 11 wherein said formatting is performed with a conversion table.
