A childhood belief about traffic lights

As a child, I could never figure out how the traffic signals knew when to change from green to yellow to red and back to green. After much puzzling over this mystery, I decided that there must be a person in the sewers at each intersection who would flip a switch whenever it was time for the light to change. I couldn't imagine why anyone would want such a job!
