Traffic signals consist of three colours: Red, Yellow, and Green. When the signal turns red, you must stop, when it turns yellow, slow down and wait, and when it turns green, go.Morgan created this new three-position traffic signal to provide an interval between stop and go. These quickly replaced the manual two-position signals that did not allow for an adequate transition at intersections, resulting in many collisions. He received a patent for his invention in 1923.A three-way signal refers to an intersection at which opposing directions do not have concurrent greens. ( Staff archives)
What is the three position traffic signal : The Morgan traffic signal was a T-shaped pole unit that featured three positions: Stop, Go and an all-directional stop position. The third position halted traffic in directions before it allowed travel to resume on either of the intersection's perpendicular roads.
