Which person invented the stop sign, traffic circle, and the one-way street?

Garrett Morgan was an African American who invented the traffic signals/lights.

Actually the very first traffic signal was located in London in 1868 but they were gas. In 1910 a non-illuminated sign was invented but the first electric traffic signal was invented in 1912. There were a few others invented between 1912 and 1923 when Garrett Morgan patented an electric automatic traffic signal in 1923.

Maestro1313, That’s what I read in black inventors history. Happy someone else confirmed it here. I see my memory is still intact. ! ! ! 😀

I think that might be Rond, not Road Point

Maestro1313, Thanks for the info, never knew!

I wonder if he's related to Brian Eno?
