[00:00:00]You stop at traffic lights every day.

[00:00:02]But traffic lights are smarter than most people think. Many people think they simply work on timers, but hidden under some roads there are sensors that detect the metal in your car. Some intersections even use cameras and radar systems to monitor traffic in real time.

[00:00:24]The central control system runs the entire traffic network. That's why sometimes the light changes just seconds after you arrive.
