Roundabouts

What is a roundabout?

A modern roundabout is an un-signalized circular intersection engineered to maximize safety and minimize traffic delay.

All traffic circulates counter-clockwise within the roundabout always to the right of the central island.

Unlike a traffic circle, such as the one located on Prince of Wales Drive at the Experimental Farm, traffic entering the roundabout must yield to traffic within the roundabout.

Characteristics of a Roundabout

• Low speed on approach
• Approaching vehicles yield to traffic within roundabout
• Vehicles drive counter-clockwise within roundabout
• Low speed on exit
• Continuous movement of traffic
