Traffic lights save lives, but do you know how they work? 🚦🤔 #engineering | Interesting Engineering

How do traffic lights REALLY work? 🤔🚦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
