Abstract

Tracking speeding violations and the use of at least one destination location are disclosed. Initially, two or more first images are received from a first camera, two or more second images are received from a second camera having a different field of view, and two or more third images are received from a third camera having a field of view overlapping with the field of the view of the second camera. Next, a speed of the first vehicle at a first time is determined. It is determined that the first vehicle exceeded a first predetermined speed limit at the first time. A unique identifier of the first vehicle and the speed of the first vehicle at the first time are then indicated. Next, it is determined that the second vehicle is stopped in the at least one destination location at a second time and that the second vehicle has left the at least one destination location at a third time that is after the second time. Finally, a unique identifier of the second vehicle, the second time, and the third time are indicated.
