1. A vehicle traffic control system comprising control circuitry configured to:
- monitor retro-reflected electromagnetic radiation and associate the retro-reflected electromagnetic radiation with a plurality of retro-reflective elements within a detection area;
identify changes in the retro-reflected electromagnetic radiation and associate the identified changes with vehicle information;
evaluate the vehicle information to determine a movement of the vehicle, a size of the vehicle, a shape of the vehicle, a position of the vehicle, or a combination thereof; and
control an automated device based, at least in part, on the evaluated vehicle information to provide a display or output associated with movement of the vehicle or a position of the vehicle, or both, within the detection area.

Abstract
A dynamic signal to noise ratio tracking system enables detection of vehicles within the field of view of the tracking system. The tracking system may include an emitter configured to emit electromagnetic radiation within an area, a detector configured to detect electromagnetic radiation reflected back from vehicles within the area, and a control unit configured to evaluate signals from the detector and control various automated devices as a result of this evaluation.
