Benefits of Roundabouts

Improved Safety for Drivers
Studies have shown that roundabouts are safer than traditional stop sign or signal-controlled intersections. Read more about the many benefits of roundabouts.

Roundabouts reduced injury crashes by 75% at intersections where stop signs or signals were previously used for traffic control, according to a study by the Insurance Institute for Highway Safety (IIHS). Studies by the IIHS and Federal Highway Administration have shown that roundabouts typically achieve:
  • A 37 % reduction in overall collisions
  • A 75 % reduction in injury collisions
  • A 90 % reduction in fatality collisions
  • A 40 % reduction in pedestrian collisions
Improved Safety for Pedestrians
Pedestrians walk on sidewalks around the perimeter and cross only 1 direction of traffic at a time. Crossing distances are relatively short, and traffic speeds are lower than at traditional intersections.

Reduce Delay, Emissions & Improve Traffic Flow

Contrary to many peoples’ perceptions, roundabouts actually move traffic through an intersection faster, and with less congestion on approaching roads. Roundabouts promote a continuous flow of traffic. Unlike intersections with traffic signals, you don’t have to wait for a green light at a roundabout to get through the intersection. Traffic is not required to stop, only yield, so the intersection can handle more traffic in the same amount of time. Less idling, in turn, reduces vehicle emissions and fuel consumption.
