Abstract
An operator system and related methods for automatically controlling access barriers including a controller associated with at least one access barrier and a transceiver associated with the controller for transmitting and receiving operational signals. The system also includes at least one proximity device capable of communicating operational signals with the transceiver based upon a position of the proximity device with respect to the barrier, wherein the controller monitors the operational signals and controls the position of the access barrier based upon the operation signals. Such a system allows for hands-free operation of the access barrier. Ground loop detectors and a global positioning system may also be incorporated into the system. And the system may be used to control the directional flow of traffic on a one-way road.
