A roundabout is a type of circular intersection or junction in which road traffic is slowed and flows almost continuously in one direction around a central island to several exits onto the various intersecting roads. In a modern roundabout, entering traffic must always yield to traffic already in the circle, and roundabouts have additional restrictions on the junction layout to give high safety. Elimination of the opportunity for the most deadly crashes at intersections (T-bone or perpendicular crashes), is the greatest asset of the intersection design. Pedestrians are routed away from the intersection into which automobiles enter to separate crosswalks located at least one full car length outside of the intersection, where they have a refuge between lanes of traffic. This enables pedestrians to only have to cope with traffic coming from one direction at a time, which is travelling slowly enough for visual engagement with drivers and encourages deference toward the pedestrians. Roundabouts, in their modern form, were standardised in the U.K., improving on the experience of traffic circles built in the U.S. following WWII, Modern roundabouts are now common in many countries around the world.

Famous quotes containing the word roundabout:
“Life is a long Dardenelles, My Dear Madam, the shores whereof are bright with flowers, which we want to pluck, but the bank is too high; & so we float on & on, hoping to come to a landing-place at lastbut swoop! we launch into the great sea! Yet the geographers say, even then we must not despair, because across the great sea, however desolate & vacant it may look, lie all Persia & the delicious lands roundabout Damascus.”
—Herman Melville (18191891)
