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

1-26. -26. (canceled)

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

obtaining traffic data indicating a plurality of traffic conditions on a road network, said traffic data includes a location description for each of said traffic conditions;

for each of said traffic conditions, formatting said location description into a traffic location code assigned by a traffic message supplier, wherein said traffic location code includes a traffic location table identification specifying one of a plurality of traffic location tables and a location identification code specifying a location on said road network; and

transmitting said traffic messages representing said traffic conditions for broadcast to a plurality of end user computing platforms having said plurality of traffic location tables, each of said traffic messages includes said traffic location code corresponding to one of said traffic conditions.

28. The method of claim 27 wherein said location description is a text description.

29. The method of claim 27 wherein said location description is a landmark.

30. The method of claim 27 wherein said location description is a point of interest.

31. The method of claim 27 wherein said location description is an address.

32. The method of claim 27 wherein said location description is a latitude and longitude position.

33. The method of claim 27 wherein said location description is a road name.

34. The method of claim 27 wherein said location description is a road name on which said traffic condition exists and a cross road name proximate said traffic condition.

35. The method of claim 27 wherein said formatting step comprises geo-coding said location description with a geographic database.

36. The method of claim 27 wherein said formatting is performed with a conversion table.

37. The method of claim 27 further comprising, for each of said traffic conditions, determining a direction of travel affected by said traffic condition.

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

obtaining traffic data indicating a plurality of traffic conditions on a road network, said traffic data includes a location description and an event description for each of said traffic conditions; and

for each of said traffic conditions, converting said location description into a location reference code and said event description into an event code assigned by a traffic message supplier.

39. The method of claim 38 wherein said event description is a traffic speed.

40. The method of claim 38 wherein said event description is an accident.

41. The method of claim 38 wherein said event description is construction information.

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

obtaining traffic data indicating a plurality of traffic conditions on a road network, said traffic data includes a location description and an expected duration for each of said traffic conditions; and

for each of said traffic conditions, converting said location description into a location reference code and said expected duration into a duration code assigned by a traffic message supplier.

43. The method of claim 42 wherein said location description is a text description.

44. The method of claim 42 wherein said location description is a point of interest.

45. The method of claim 42 wherein said location description is an address.

46. The method of claim 42 wherein said location description is a road name.

47. The method of claim 42 wherein said location description is a latitude and longitude position.
