A roundabout is a circular intersection where drivers travel around a center island. Roundabouts are referred to as circles, rotary, island, rotunda by locals. The traffic flows in roundabouts occur in a single direction around the central island. Some of them also act as a landmark to that city. Circular junctions are an older form of roundabouts, which began in the 1960s. Many countries adopted them for safety, for better traffic flow. These are classified into many types such as single lanes, mini (smaller ones), balconies, motorways (large ones), signalized, bicycle/pedestrian. Here are the 10 biggest roundabouts in the world:
