Publicizes the importance of traffic safety, the prevention of traffic accidents, and the necessity of lowering the highway death rate. But Cleveland, Ohio, is largely credited as the home of the first electric traffic signal. The light was designed by James Hoge and installed at the corner of 105th Street and Euclid Avenue on August 5, 1914. Hoge’s design used four pairs of red and green lights mounted on a corner post. They were wired to a manually operated switch in a control booth using a system that prevented the possibility of conflicting signals. The lights had words “stop” and “move” in them and a buzzer to warn of impending color changes. Hoge’s system also permitted police and fire stations to chance the signals when there was an emergency.
