Smart traffic light

Okay kiddo, imagine you are in a park and there is a lot of traffic. Cars and bicycles are passing by each other, and the traffic light controls when they can stop or go.

A smart traffic light is a special kind of traffic light that uses technology to help make the traffic flow better.

It has sensors that can detect the number of cars waiting at the light and how fast they are moving. This helps the light decide how long it should stay green or red.

So, if there are a lot of cars waiting on one side of the road, the smart traffic light can change to green for a longer time so that everyone can get through faster.

In addition, some smart traffic lights can be connected to other traffic lights nearby so they can communicate and work together. This helps to make sure that traffic flows smoothly along a whole road or even a whole city!

So, basically, a smart traffic light is a really clever traffic light that can help make traffic go faster and smoother.
