What is a roundabout or traffic circle?

• A. A type of intersection that increases congestion
• B. A circular intersection that promotes traffic safety
• C. A one-way street with multiple lanes
• D. A type of signalized intersection

Answer: (B)

A roundabout or traffic circle is best defined as a circular intersection that promotes traffic safety. This design encourages a continuous flow of traffic, reducing the likelihood of high-speed collisions often seen at traditional intersections. Vehicles entering the roundabout yield to those already traveling within it, which helps to minimize stops and delays, ultimately enhancing the overall efficiency of traffic movement. In addition to improving traffic flow, roundabouts have been shown to decrease the severity of accidents. The reduced speed at which vehicles navigate through a roundabout lowers the chances of high-impact collisions, making it safer for all road users, including pedestrians and cyclists. Therefore, this design is not only effective in promoting safety but also in managing the distribution of traffic in busy areas without the need for traffic signals.
