Model animating with authentic darkout between light changes. The darkout was the cam ratchet advancing on the old Crouse Hinds "KS" electromechanical controllers.
That is old style light cycle. The first time I have seen red on both direction before going to green for approximately 2 seconds was 1973 when they erect traffic lights at the intersection of Wolf Rd and Kensington Rd, Mount Prospect, IL, USA. (The google map show how much expanded since two lane intersection as far as back as 1968 with stop sign as I remember).
