Traffic equipment used by the Cleveland Police in 1925.The Cleveland Police used traffic semaphores to bring order and safety to our streets. The officer set up the semaphore in the middle of the intersection and controlled the flow of traffic by manually rotating the semaphore with its “Stop” and “Go” arms. If needed, the officer could add options like “No Left Turn” or No Right Turn.” The officer also used hand and whistle signals.Although electric traffic lights replaced semaphores at many intersections in Cleveland, semaphores remained in use into the 1970s. Easy to use and easy to transport, semaphores were ideal for controlling vehicle and pedestrian traffic for major events at Cleveland Stadium, Public Square and other venues in the city.Learn more: ...
