Roundabouts also have a large number of very positive environmental impacts:

  • Less pollution due to fewer stops, starts and idling time
  • Less power consumption due to no signal equipment
  • Often need less pavement and right of way area
  • Quieter operation than traditional intersections
  • More aesthetically pleasing and efficient
  • Roundabout intersections are also friendlier to both pedestrian and bicycle traffic. Pedestrians should walk around the outside, while bicycles flow with motorized traffic.
