Abstract

1421200 Road traffic signals OMRON TATEISI ELECTRONICS CO 11 May 1973 [17 May 1972] 22603/73 Heading G4Q In a road traffic signal control system incorporating a local controller for the traffic signals at each intersection and a central computer-controlled station for controlling local controllers, a " hold " signal from the central station inhibits the local controllers unless the central station fails, in which case the hold signal is not transmitted and this is recognized at the local controllers to cause them to act according to local pre-set timers; according to the invention a hold signal is transmitted only when the phases at the central and local apparatuses are in coincidence.
