Who Created the First Ever Traffic Signal?
The first electric traffic signal was installed in Cleveland, OH, USA, in 1914 by the American Traffic Signal Company. Now there are more than 272,000 traffic signals nationwide. The man credited with inventing the traffic signal and applying for the 1923 patent is Garrett Morgan. Said to be the first African American to own an automobile in Cleveland, Morgan also invented the gas mask and the zigzag attachments for sewing machines.
