Preferred Intersection Design
Roundabouts are becoming a preferred intersection design for many reasons including increased safety, reduced wait times, and less maintenance costs.
- Reduce accidents by 48% (FHWA)
- Reduce serious accidents by 80% (FHWA)
- Reduce travel speed at the roundabout to between 15 and 25 miles per hour, yet still allowing traffic to move
- Single Lane Roundabouts have only 8 conflict points where an accident may occur, whereas a traditional intersection has 32
- Roundabouts are a safer intersection solution than traffic signals or traditional non-signalized intersections. Because of the slower vehicle speeds, the chance of a fatal or serious injury crash at a roundabout is very small. At two-way stop controlled or signalized intersections, speeds are much higher; the T-bone crashes that are common at these types of intersections can be devastating, sending many drivers to the hospital.
- Simply put, roundabouts save lives
Idle Time & Gas
Reduced idle time saving time and money (less gas) through the following:
- Efficient way to move heavy traffic
- No stop signs or traffic signals to slow down traffic
- No need to operate and maintain traffic signal
- Still functions despite power outages
- Cost efficient
