Abstract
A device for controlling a traffic light, where the controlling of the traffic light is dependent upon receipt and recognition of vibrations. The device includes a vibration receiver for detecting vibrations transmitted through the ground, a processor for converting one or more of the vibrations into a control signal and a controller to trigger a traffic light in response to the control signal. The device may also include a vibration generator, e.g., at least one channel or groove in a traffic-bearing surface. The vibration generator preferably facilitates the production of a pattern of vibrations when the tire of a vehicle passes over the vibration generator. Further, the device may include a vibration receiver, capable of detecting a pattern of vibrations and producing a pattern of signals corresponding to said pattern of vibrations.
