Abstract

A method includes configuring a plurality of sub-bounding areas within a primary bounding area. An aggregate traffic message includes traffic information aggregated from the sub-bounding areas and is broadcast throughout the primary bounding area. The roads within the primary bounding area are associated with road classifications, and individual traffic messages associated with those roads are generated. Sub-bounding areas within the primary bounding area are associated with particular road classifications. Individual traffic messages (for particular roads) are selected for inclusion in the aggregate traffic message (broadcast over the primary bounding area) if those messages are associated with a road having a road classification that matches a road classification of a sub-bounding area in which the road is located. The aggregate traffic message is generated by combining the selected individual traffic messages and is transmitted to a station importer.

Claims

1. A method for use in a traffic information system, the method comprising:

receiving a Transport Protocol Experts Group (TPEG) traffic message and associated bounding area definitions, wherein the associated bounding area definitions define a primary bounding area, and at least one sub-bounding area located within the primary bounding area;

configuring the TPEG traffic message into TPEG frames for broadcast to a primary bounding area based on the associated bounding area definitions by;

determining one or more road classifications associated with the TPEG traffic message;

comparing the one or more road classifications associated with the TPEG traffic message with sub-bounding area information to determine whether a road classification of the TPEG traffic message matches a road classification associated with the sub-bounding area;

configuring, for each road classification of the TPEG traffic message matching the road classification associated with the sub-bounding area, the TPEG frames by adding the TPEG traffic message;

configuring, for each road classification of the TPEG traffic message not matching the road classification associated with one or more sub-bounding areas but matching the primary bounding area road class, the TPEG frames by adding the TPEG traffic message; and

transmitting the TPEG frames to a station importer.

2. The method of claim 1 further comprises when it is determined that no additional TPEG traffic messages remain to be configured into TPEG frames, delivering configured TPEG frames to the station importer.

3. The method of claim 1, wherein a road class associated with a message is determined based on information included in the TPEG traffic message including any of:

a road classification associated with a road associated within the TPEG traffic message;

a list of road classes associated with TPEG traffic messages;

or information linking the road to traffic information included in the TPEG traffic messages.

4. The method of claim 1, wherein the comparing the one or more road classifications associated with the TPEG traffic message with sub-bounding area information includes identifying a traffic incident associated with a road having a road classification and any TPEG traffic message including information about that traffic incident.

5. The method of claim 1, wherein transmitting the TPEG frames to a station importer occurs when all of the TPEG traffic messages have been processed and all the TPEG frames configured.

6. The method of claim 1 further comprises generating an updated individual TPEG traffic message at a refresh rate determined, at least in part, on the road classifications of a road with which the updated individual TPEG traffic message is associated.

7. A system comprising:

a memory coupled to the processor, the memory storing bounding area information defining a primary bounding area, and at least one sub-bounding area located within the primary bounding area, the primary bounding area and the at least one sub-bounding area being independently associated with road classifications;

a network interface coupled to the processor, the memory, and configured to be coupled to a packet-switched communication network, the network interface configured to receive;

traffic data including speed and incident data;

road vector definitions associated with roads located within the primary bounding area, the roads having road classifications;

the processor configured to;

receive a Transport Protocol Experts Group (TPEG) traffic message and associated bounding area definitions;

determining one or more road classifications associated with the TPEG traffic message;

comparing the one or more road classifications associated with the TPEG traffic message with sub-bounding area information to determine whether a road classification of the TPEG traffic message matches a road classification associated with the sub-bounding areas;

configuring, for each road classification of the TPEG traffic message matching the road classification associated with the sub-bounding areas, the TPEG frames by adding the TPEG traffic message; and

configuring, for each road classification of the TPEG traffic message not matching the road classification associated with one or more sub-bounding areas but matching the primary bounding area road class, the TPEG frames by adding the TPEG traffic message.

8. The system of claim 7, wherein the processor is further configured to transmit the primary bounding area TPEG frames to a station importer.

9. The system of claim 7, wherein the processor is further configured to:

determine which one or more road classifications to associate with the at least one sub-bounding area based, at least in part on, information included in the TPEG traffic message including any of;

a road classification associated with a road associated within the TPEG traffic message;

a list of road classes associated with TPEG traffic messages;

or information linking the road to traffic information included in the TPEG traffic messages.

10. The system of claim 7, wherein the processor is further configured to:
