Especially for American drivers who are used to flexible lane changes, navigating a turbo roundabout for the first time may seem unintuitive. The secret is to decide on your lane well before you ...

Roundabouts, also known as traffic circles or rotaries, are circular intersections designed to improve traffic flow and safety. They offer several advantages over conventional intersections ...

“Crashes happen at more of a sideswipe-type of an angle rather than than the T-Bone,” said Tony Kutzke, the city engineer for Woodbury, which has 22 roundabouts and counting.

Instead of right-angle or T-bone collisions in an intersection, vehicles will typically hit others in a roundabout at a 45 degree angle that could glance off a car rather than stop one in its tracks.

Sacramento officials are considering a roundabouts pilot project. Here’s how the intersection design could help dangerous Sacramento roads.

Roundabouts can have many lanes, not just one lane. Single-laned roundabouts can have more than 20,000 cars traveling through them every day, and double-laned roundabouts can have up to 50,000.

A Cape Girardeau business is banking on beautifying a roundabout while marketing itself at the same time. Montgomery Bank has “adopted” the roundabout at Independence Street and Gordonville Road.

The magic roundabout is more glorious still, an artifact of 20th century optimism and a belief that all things can be more perfect. It gives the cars multiple pathways to the same destination. As ...
