Invention of the Traffic Light by William L. Potts in 1920.
More Details...Police Officer William L. Potts of Detroit, Michigan,
decided to do something about the problem caused by the ever increasing number of automobiles on the streets. What he had in mind was figuring out a way to adapt railroad signals for street use. Potts used red, amber, and green railroad lights and about thirty-seven dollars worth of wire and electrical controls to make the world’s first 4-way three color traffic light. It was installed in 1920 on the corner of Woodward and Michigan Avenues in Detroit. Within a year, Detroit had installed a total of fifteen of the new automatic lights.

As Betsy B said, Garrett Augustus Morgan. Just look it up on Yahoo! under "traffic light inventor."
