transmitting the tracking data to at least one of the plurality of detected objects by the device, the tracking data including the number of detected objects and the speeds and positions of the plurality of detected objects; and

transmitting a collision warning signal to at least one of the plurality of detected objects based on the number of detected objects, the speeds and positions of the plurality of detected objects, a predetermined average travel time through the intersection, and a predetermined number of vehicles that can enter and exit the intersection during a traffic light cycle.

2. The method of claim 1 , wherein detecting the plurality of objects includes detecting vehicles by at least one of a solid-state radar sensor and chip based radar sensor, wherein the integrated radar sensor of the device is configured to track the plurality of 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 tracking includes continuous monitoring of object speed, heading, and position relative to objects detected in the intersection.

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

6. The method of claim 1 , wherein the plurality of detected objects includes a vehicle and a pedestrian, and the method further comprising transmitting an alert signal to the vehicle about presence of the pedestrian.

7. 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 intersection.

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