1922 Philadelphia’s Hand-Operated Traffic Control
As soon as cars hit the streets, minor accidents, or “fender-benders,” became frequent. It was evident that rules were essential to avoid collisions with other vehicles, pedestrians, or buildings. To tackle this issue, drivers started using signals to navigate intersections safely. Before the era of electric traffic lights, the primary solution was manual signals, as shown in the photograph above. A traffic control operator was responsible for manually switching the sign from “stop” to “go,” ensuring order on the roads.
