Yes and no.
African-American Garrett Morgan is credited with inventing the electric automatic traffic light which was based on semaphore. The system was quite different to another system invented by a Detroit police officer by the name of William Potts. He was the first to develop the first 4-way 3-colour light system, and it was installed in Detroit in 1920.
However, both of these systems were preceded by traffic lights that were around even before cars. The very first traffic light in the world was located at a London intersection in 1868, and was a hand-held revolving gas lantern with red and green signals. This was not an entirely successful experiment, as the light exploded early in 1869, injuring the policeman who was operating it.
