A roundabout is a circular intersection designed to slow traffic while lowering delays. Roundabouts are designed for both large and small vehicles. There are no traffic signals. The roundabout features a central island around which traffic circulates. Roundabouts can be either single-lane or double-lane.

How do they work?

The general principle for using a roundabout is "yield at entry."  Yield to pedestrians in the crosswalks and traffic already in the roundabout. All traffic moves in a counterclockwise direction. You will always make a right turn to enter the roundabout. Once you have entered the roundabout you will proceed around the center island and take the desired right hand turn to exit the roundabout. For an interactive demonstration please select the graphic link below. You will need the Macromedia Flash player to view the interactive roundabout.

 

Fewer Crashes	Statistics gathered in the United States show that roundabouts can reduce fatal and injury accidents by as much as 76 percent. Roundabouts encourage slower speeds and calmer traffic. Accidents tend to be less severe with fewer injuries.
Quicker/         Less Delay	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 or pedestrians.  Motorists yield rather than stop.  A higher traffic flow quickens your commute.  Click here to print a brochure about roundabouts.
