Okay kiddo, so you know when we drive on the road, there are traffic lights that tell us when to stop or go? Well, in Brisbane, they have something called the linked intersection signal system which makes the traffic lights talk to each other and work together.
So imagine you're driving down the road and you see a green light ahead, but as you get closer, it turns red. That can be pretty frustrating, right? Well, with the linked intersection signal system, the traffic lights know when you're coming and will time it so that you can keep driving without having to stop at every red light.
This is called a "green wave", and it means that if you drive at the right speed, you can keep moving through a series of green lights without having to stop. It's like surfing the green wave!
The linked intersection signal system also helps emergency services like ambulances get through traffic faster, by changing the lights ahead of them to green so they can get to where they need to go quickly.
Overall, the linked intersection signal system is a clever way of using technology to make our roads safer and help us get where we need to go faster.
