Abstract

Disclosed herein are systems and methods for exchange of travel data in a roadway information system associated with a first roadway vehicle and a second roadway vehicle. In one embodiment, the roadway information system may comprise, for example, a first mobile client system associated with the first roadway vehicle, a second mobile client system associated with the second roadway vehicle, a wireless communication network, and a processing system communicatively coupled to the wireless communication network. The first mobile client system may deliver first travel related data to the processing system via the wireless communication network. The processing system may deliver second travel related data to the second mobile client system via the wireless communication network, where the second travel related data relates at least in part to the first travel related data.

Claims

1. A mobile client system, comprising:

at least one processor for determining location information of the mobile client system,

wherein said determined location information comprises at least one of the following;

a current location information of the mobile client system and a location information designated by a user of the mobile client system,

wherein the mobile client system communicates said determined location information to a processing system, and

wherein the mobile client system receives from said processing system travel related data based at least in part on location information communicated by at least one of a plurality of other mobile client systems and on said determined location information of the mobile client system.

2. The system according to claim 1, comprising a wireless transmitter that transmits said location information to said processing system.

3. The system according to claim 1, comprising a wireless receiver that receives said travel related data for said at least said second mobile client system.

4. The system according to claim 1, wherein said at least one processor for calculating said location information of the mobile client system comprises a Global Positioning System (GPS).

5. The system according to claim 1, wherein said at least one processor calculates said location information based on signal triangulation.

6. The system according to claim 1, comprising a display that displays at least a portion of said received travel related data.

7. The system according to claim 1, wherein said received travel related data comprises at least one of the following:

velocity information and traffic information.

8. The system according to claim 1, wherein the mobile client system receives from said processing system traffic information for a roadway location, and wherein said traffic information is calculated based at least in part on velocity of a plurality of vehicles located at or near said roadway location.

9. The system according to claim 8, wherein said roadway location is proximate to said communicated location information of said mobile client system.

10. The system according to claim 1, wherein the mobile client system receives from said processing system second travel related data for the mobile client system, based at least in part on said communicated location information of the mobile client system.

11. A processing system, comprising:

at least one processor for calculating travel related data for at least one of a plurality of mobile client systems,

wherein said plurality of mobile client systems is communicatively coupled to said at least one processor,

wherein said at least one processor receives location information for a first mobile client system and a second mobile client system, and

wherein said at least one processor calculates said travel related data for said at least one of said plurality of mobile client systems, based at least in part on said received location information for said first mobile client system and said second mobile client system.

12. The system according to claim 11, comprising a wireless receiver that receives said location information for said first mobile client system and said second mobile client system.

13. The system according to claim 11, comprising a wireless transmitter that transmits said calculated travel related data to said at least one of said plurality of mobile client systems.

14. The system according to claim 11, wherein the processing system transmits to said at least one of said plurality of mobile client systems traffic information for a roadway location proximate to a location of at least one of the following:

said first mobile client system and said second mobile client system.

15. The system according to claim 14, wherein said traffic information is calculated based at least in part on velocity of a plurality of vehicles located within at or near said roadway location.

16. The system according to claim 11, wherein said travel related data comprises at least one of the following:

traffic information and location information.
