Safety Benefits of Roundabouts
- Statistically, roundabouts are vastly safer than conventional signalized intersections*:
- 35% reduction in all accidents
- 78% reduction in fatal and injury accidents
- 89% reduction in accident-related pedestrian injuries
- Unlike a signalized intersection, roundabouts don't force drivers to stop when there is no traffic. Motorists are only required to stop when there is conflicting traffic.
- With fewer stops and hard accelerations, less time idling means reduced pollution and fuel use.
- They require no electronic operation, which results in operational cost savings.
- They complement other community values with quieter operation and are aesthetically more pleasing.
Fact:
In the past five years, there have been no fatal accidents at roundabouts in CDOT's Northwestern region (Region 3).
