Circular intersection type
Rotary describes circular motion or arrangement.
A rotary engine has parts that rotate rather than reciprocate.
A rotary phone has a circular dial you turn to select numbers.
As a noun, a rotary is a traffic circle—an intersection where vehicles move in one direction around a central island.
