Abstract

A traffic information system for a vehicle comprises a global positioning system (GPS) associated with the vehicle that selectively generates location and vector data. The traffic information system includes a transmitter. A control module receives the location and vector data and wirelessly transmits the location and vector data using the transmitter. A remote traffic monitoring system receives the location and vector data and determines a first lane that the vehicle is located in based on at least the location and vector data.

8. The traffic information system of claim 1 wherein said control module monitors lane changes of said vehicle and transmits said vector and location data when said vehicle changes lanes greater than a lane change frequency threshold.

9. The traffic information system of claim 1 wherein said control module monitors changes in speed of said vehicle and transmits said vector and location data when said vehicle speed change is greater than a speed change threshold.

10. The traffic information system of claim 1 wherein said control module is integrated with said GPS.

11. The traffic information system of claim 1 further comprising the remote traffic monitoring system that determines a lane of an accident based on at least the location and vector data.

12. The traffic information system of claim 1 wherein the remote traffic monitoring system generates a lane change suggestion according to the location and vector data.

13. The traffic information system of claim 1 wherein the remote traffic monitoring system determines a direction of travel of the vehicle based on the location and vector data.

14. The traffic information system of claim 2 wherein the traffic reports include a confidence level associated with the location and vector data.

15. The traffic information system of claim 14 wherein the confidence level is high when the location and vector data indicates that the vehicle is traveling at a first speed and the confidence level is low when the location and vector data indicates that the vehicle is traveling at a second speed.

16. A traffic information system for a vehicle, comprising:

global positioning means associated with said vehicle for selectively generating location and vector data;

transmitting means for transmitting data; and

control means for receiving said location and vector data and for wirelessly transmitting said location and vector data using said transmitting means, wherein said control means communicates with remote traffic monitoring means for receiving the location and vector data and for determining a first lane that the vehicle is located in based on at least the location and vector data.
