Abstract
Abstract A traffic control system utilizing digital timing signals, which can be derived from locally available 60 hertz power, to time each traffic interval. The timing signals are transformed to pulses marking the initiation of each traffic interval. These in turn are converted into signals which can be transmitted, for example via two pair of electrical conductors, from a remote traffic guidance center to a local traffic controller in which they are reconverted to signals for each traffic phase. These phase signals are then steered to switching circuits which control energization of the traffic signal indicators. The timing circuit can be utilized independently as a cyclic timer, either with or without conversion for transmission to a remote location.
