A well designed strategically placed roundabout has several benefits.
- Safety - Slower speeds and less conflict points reduces the frequency and severity of accidents. National studies have indicated that serious and fatal crashes have been reduced by 70 to 90 percent at locations where roundabouts were installed.
- Operation - Overall delays may be reduced due to the smooth flow of vehicle traffic rather than the stop-and-go traffic of normal intersections.
- Aesthetics - The central island is often landscaped to help beautify the intersection.
