Abstract
A coordinated traffic signal control system comprising a plurality of signalized intersections with controllers including coordination means to relate cycle timing between intersections without dedicated interconnecting communication channels. Coordination means including radio receiver tuned to receive broadcast standard time such as from National Bureau of Standards Station WWV, cycle timers related to data from broadcast time after iterative broadcast data check, signal cycle program selection from a plurality of programmable signal cycle program data inputs with cycle length and offset selection through time of day or traffic count program outputs, such a system providing fixed cycle timing relationship with other similarly equipped intersections that responds to anticipated or detected changes in traffic patterns.
