A modern roundabout is one of several types of circular intersections in which traffic flows around a center island. It operates with yield control at the entry points and gives priority to vehicles within the roundabout.

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, traffic from only one direction)
• Less vehicle delay and pollution (no waiting at red lights, complete stops rarely necessary)
