The Modern Roundabout

FL RoundaboutA modern roundabout is one of several types of intersections in which traffic flows around a circular center island.

A modern roundabout is NOT the same as high-speed rotary interchanges, once common in the Northeast states. Rotaries are larger and operate poorly because they require merging to enter and require risky lane changes to exit. See Rotaries vs. Roundabouts. A modern roundabout also is NOT the same as a traffic circle or circle road, such as within the Tamarack Village shopping area in Woodbury, where lane changes may be made within the circle and circulating traffic makes right or left turns to exit the circle road. See Traffic Circles vs. Roundabouts.

At a modern roundabout, there is no merging because entering drivers must YIELD (wait until all traffic is clear before proceeding). There are no lane changes in a modern roundabout because, as with any other intersection, the correct lane must be chosen before entering. Always keep to the left to make left turns through a roundabout, just like at any other intersection.

Advantages of Roundabouts

Roundabouts have several advantages over signals and stop signs, including:
  • Fewer injury crashes and fatalities (no “t-bone” or head-on crashes)
  • Improved pedestrian safety (low speeds, fewer lanes to cross, minimal delays, traffic from only one direction)
  • Less vehicle delay and pollution (no waiting at red lights, complete stops are not usually necessary)
