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 39%
  • Reduce serious accidents by 75%
  • 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 unsignalized 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

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

Less Money

Roundabouts cost less to maintain by the following ways:

  • No need to maintain traffic signal
  • Still functions despite power outages
