No one really controlls the traffic lights. A computer system controls the traffic lights, and no humans are involved with controlling the traffic lights day in and day out. It is all automated these days.

An uncontrolled intersection is an intersection that has no traffic controls -- no traffic signals, stop sighs, yield signs, etc.
Traffic control ranges from traffic cones and drums to the flaggers who hold the "Stop/Slow" signs. It can also include the cameras that DOTs use to look at traffic.
