Robot
Noun
signaling devices positioned at road intersections, pedestrian crossings, and other locations in order to control the flow of traffic
turn left at the second robot
It is believed that the name was adopted when people were no longer required to control traffic and robotic like machinery (traffic lights) were rolled out.
I guess the term makes sense if you think about how the system replaced a human controlling traffic.
