Roughly 10 years ago, we started to see traffic circles (or "round-abouts") pop up across the US. What is a traffic circle? Well, if you don't know, a traffic circle is exactly what is sounds like; it is an area of traffic designed in a circular pattern. It allows for the flow of traffic to be continuous for those within the circle and for traffic to safely enter the traffic circle when there is no traffic approaching from the left. Traffic circles reduce the likelihood of side impact collisions found at the traditional 90-degree intersection. They also eliminate the need for electronic traffic control as the traffic circle is its own source of traffic control. The Department of Transportation (DOT) claims a 75% reduction in injury collisions and a 90% reduction in fatal collisions as a result of traffic circle creation. Simply put, traffic circles are a safer alternative to the traditional intersection and they also allow for a smoother flow of traffic.
