ABSTRACT:
A traffic control system is provided wherein the green and/or red signal lights are blinked momentarily at a predetermined interval before the direction of traffic is changed, and wherein a marker is placed along the roadway at a normal distance of travel within the timing of the blink signal to enable motorists to gauge their driving to save gasoline and achieve greater safety solely by noting their location relative to the marker when the blink signal occurs. Further, the invention relates to the use of this traffic signalling system in connection with a semi-actuated controller having a synchrolizer providing a background cycle, wherein the timing of the blink signal and the yellow caution signal is obtained from the synchrolizer. A specific feature resides in a novel means to prevent the synchrolizer from triggering a change in direction of traffic without a prior actuation of the blink signal.
