Why use a Roundabout?

A well designed strategically placed roundabout has several benefits.

  • Safety - Slower speeds and less conflict points reduces the frequency and severity of accidents.
  • Operation - Delays are 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.
