What is the purpose of a traffic circle or roundabout?

• A. To eliminate all traffic
• B. To improve traffic flow and reduce collisions
• C. To increase traffic speed
• D. To provide more parking options

Answer: (B)

The purpose of a traffic circle or roundabout is primarily to improve traffic flow and reduce the likelihood of collisions. Roundabouts are designed to allow vehicles to move continuously in a circular pattern, which significantly reduces the need for stop signs and traffic signals. This continuous movement minimizes delays and helps keep traffic flowing smoothly. Additionally, roundabouts are designed with features such as yielding and merging, which promote safer interactions between vehicles. By forcing vehicles to slow down as they enter, collisions often occur at lower speeds, leading to less severe accidents. This design contrasts with traditional intersections, where accidents often happen at higher speeds and can result in more serious injuries. The functions of a traffic circle or roundabout directly contrast with options related to eliminating all traffic, increasing traffic speeds, or providing more parking options, as these do not align with the primary goals of improving traffic efficiency and safety.
