Why Roundabouts Are Taking Over U.S. Roads
Love them or hate them, roundabouts are popping up everywhere in the U.S. They’re efficient, safer, and surprisingly eco-friendly. Here’s why this modern roadway design is gaining traction.
What Are Roundabouts?
Roundabouts are circular intersections where traffic flows counterclockwise around a central island. Instead of stop signs or traffic lights, drivers yield to vehicles already in the circle. This design encourages continuous movement and slows vehicles down, reducing crash risks.
Why Are They Safer?
Traditional intersections have 32 potential conflict points, often leading to T-bone crashes. Roundabouts cut that number to just 8, and vehicles travel at slower speeds. According to the Federal Highway Administration (FHWA):
- Serious crashes drop by 90% when stop signs are replaced by roundabouts.
- Signalized intersections see an 80% reduction in serious crashes when converted.
