A roundabout is a circular junction where two or more roads meet, and traffic moves in a clockwise direction around a central island. There are several synonyms for the word roundabout, including traffic circle, rotary, circulator, gyratory, or circle intersection. A traffic circle is a term mostly used in the US, while rotary is commonly used in the UK. A circulator is another synonym that refers to a central point where traffic flows in circles. A gyratory intersection is a large roundabout where several lanes of traffic meet. Whatever it is called, a roundabout is an efficient and safer traffic solution than traditional intersections, as it reduces the risk of accidents and improves traffic flow.
