Why do some intersections use roundabouts, while others rely on traffic lights? 🚗🚦 Both are designed to control traffic, but they work in completely different ways.
In this episode of History of Simple Things, we explore the surprising history, engineering, safety, efficiency, and drawbacks of roundabouts vs. traffic lights. Find out why roundabouts can reduce serious crashes and unnecessary stopping, why traffic lights remain essential in busy cities, and how engineers decide which system works best for a particular intersection.
You might never look at an intersection the same way again!
