Abstract

A system and methods are provided for providing intersection positioning data. In one embodiment, a method includes detecting one or more objects by a device, wherein the one or more objects are detected relative to at least a portion of a roadway by an integrated radar sensor of the device, and tracking one or more detected objects by the device to determine tracking data, wherein tracking includes determining a number of detected objects, determining speed of the one or more detected objects and determining position of the one or more detected objects. The method may also include outputting the tracking data by the device. The system and methods may advantageously be employed for transmitting one or more of a collision warning, red light warnings, red light violation warnings and operation characteristics of objects during a traffic incident relative to intersection.

Claims

1. A method for providing intersection positioning data, the method comprising:

detecting one or more objects by a device, wherein the one or more objects are detected relative to at least a portion of a roadway by an integrated radar sensor of the device;

tracking one or more detected objects by the device to determine tracking data, wherein tracking includes determining a number of detected objects, determining speed of the one or more detected objects and determining position of the one or more detected objects; and

outputting the tracking data by the device.

2. The method of claim 1, wherein detecting one or more objects includes detecting vehicles by at least one of a solid-state radar sensor and chip based radar sensor, wherein the resolution of a radar sensor of the device is configured to track one or more objects simultaneously.

3. The method of claim 1, wherein detected objects relate to one or more of a vehicle, pedestrian, and movable objects in general.

4. The method of claim 1, wherein the portion of a roadway is one of an intersection, lane merge, highway entrance, and parking location.

5. The method of claim 1, wherein tracking includes continuous monitoring of object speed, heading, and position relative to objects detected in an intersection.

6. The method of claim 1, wherein tracking includes estimating vehicle dimensions and vehicle path.

7. The method of claim 1, wherein outputting includes transmitting tracking data to one or more vehicles associated with detected objects.

8. The method of claim 1, wherein outputting data includes transmitting a collision warning signal to one or more detected objects based on the tracking.

9. The method of claim 1, wherein tracking includes receiving data by the device from a scanning device detecting objects at a location different from the location of the intersection.

10. The method of claim 1, further comprising determining traffic control information for the portion of the roadway, and outputting data based on the traffic control information.

11. A system for providing intersection positioning data, the system comprising:

an integrated radar sensor configured to detect one or more objects, wherein the one or more objects are detected relative to at least a portion of a roadway; and

a processor configured to

track one or more detected objects to determine tracking data, wherein tracking includes determining a number of detected objects, determining speed of the one or more detected objects and determining position of the one or more detected objects; and

output the tracking data.

12. The system of claim 11, wherein the integrated radar sensor is at least one of a solid-state radar sensor and chip based radar, and the integrated radar sensor is configured to detect one or more objects, wherein the resolution of a radar sensor configured to track one or more objects simultaneously.

13. The system of claim 11, wherein detected objects relate to one or more of a vehicle, pedestrian and movable objects in general.

14. The system of claim 11, wherein the portion of a roadway is one of an intersection, lane merge, highway entrance, and parking location.

15. The system of claim 11, wherein tracking includes continuous monitoring of object speed, heading, and position relative to objects detected in an intersection.

16. The system of claim 11, wherein tracking includes estimating vehicle dimensions and vehicle path.

17. The system of claim 11, wherein outputting includes transmitting tracking data to one or more vehicles associated with detected objects.

18. The system of claim 11, wherein outputting data includes transmitting a collision warning signal to one or more detected objects based on the tracking.

19. The system of claim 11, wherein tracking includes receiving data from a scanning device detecting objects at a location different from the location of the intersection.

20. The system of claim 11, wherein the processor is further configured to determine traffic control information for the portion of the roadway, and to output data based on the traffic control information.

21. A device for providing intersection positioning data, the device comprising:

a positioning module configured to determine position of the device;

an integrated radar sensor configured to detect one or more objects, wherein the one or more objects are detected relative to at least a portion of a roadway; and

a processor configured to

track one or more detected objects to determine tracking data, wherein tracking includes determining a number of detected objects, determining speed of the one or more detected objects and determining position of the one or more detected objects; and

output the tracking data.
