Welcome to Roadscapes Wednesday, each week this post will talk about roads and infrastructure related topics. I am called the “road geek” for a good reason, I love roads and love talking about roads!
Traffic lights are an essential part of our road infrastructure, but have you ever wondered how they work? Traffic signals are those three lights that tell you when to stop, when to go, and when to proceed with caution.
If these traffic lights weren’t used, our intersections would be chaotic! Watch the video from Interesting Engineering to discover how traffic lights work and how they are made!
