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.

In a traffic control system comprising red, green and yellow signal lights for each direction of traffic at an intersection wherein said lights are controlled to cause only one of said lights to be “on”at any one time in any one direction, and the lights in each direction are shifted at intervals to red and green to indicate changes in the direction of traffic: the combination of a controller with means to provide a short momentary blink of said green and/or red signal lights at a predetermined interval before each change in direction of traffic at said intersection with continuation of the light in a steady condition after the blink; and a marker on a roadway to said intersection placed at a distance from the intersection equal approximately to the normal distance of travel on the roadway within the timing of said blink signal whereby to enable the motorist to interpret said blink signal solely by his location relative to the marker when the blink signal occurs to achieve greater safety and to save gasoline.
