243K views · 3.4K reactions | How do traffic lights REALLY work? 樂Traffic lights work using a combination of fixed timers and sensors that detect vehicles, pedestrians, and even bicycles. This information is sent to a central controller, the "brain" of the intersection, which then decides when to change the lights based on pre-programmed cycles and the real-time inputs it receives! #science #physics #engineering #technology | Learning with Lyrics | Facebook
