The big idea
In some cities, traffic lights aren't on a fixed timer anymore. They have AI cameras that watch how many cars are waiting and change the lights to keep traffic flowing better.
Some examples
- AI lights stay green longer when many cars are waiting.
- They can give buses extra green time.
- Some watch for emergency vehicles and clear a path.
- They can make crosswalks longer if AI sees lots of people walking.
Try it!
Next time you wait at a stoplight, notice how long it stays red. Some cities use AI to time it!
