Which U.S. city installed the world’s first electric traffic light?
-New York City
Answer: The world’s first electric traffic signal was put into place on the corner of Euclid Avenue and East 105th Street in Cleveland, Ohio, on this day in 1914. The device used red and green lights with a buzzer that warned when the color was about to change. The invention was designed by James Hoge, who received a U.S. patent in 1918. His “municipal traffic control system” displayed electrically-powered STOP and MOVE signs mounted on posts at each corner of an intersection that were wired to a manually-operated switch housed inside a control booth nearby.
