The roundabout is informally called a rotunda or traffic circle. It is the simplest and oldest example of a freeway. There's a big roundabout in Cebu City. The oldest roundabout in the world is 100 years! The advantage of using a roundabout is that traffic lights are not required because all vehicles will be slowing down as they approach the roundabout. They will initially be all turning right and go in their specific destinations when they leave the roundabout.
