Have you ever sat at a traffic light for absolutely ages even when there’s no other car there?
These traffic lights could use information from CCTV cameras and people’s sat navs to automatically change the traffic signals as the road conditions change.
That means no more sitting at red lights! It’s something we will see more of in the future.
Things like that will form the future of smart cities. It’s all about using internet technology and creating connections to make things run more smoothly.
Because we and technology can use the internet to share data real time, we can see how people are using things like the road network – or even water and electricity – so that people can make sure the supply is in the right place at the right time.
Of course, more technology means there’s more to hack…
Smart cities have to be super smart in the way they protect the information and technology they’re using.
Safety is something technologists take very seriously – teams all over the world are working on it!
