Roundabouts

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

Other Advantages

• No need to operate and maintain traffic signal
• Still functions despite power outages
• Cost efficient
