AÃ?roundaboutÃ?is a type of circularÃ?intersectionÃ?or junction in which road traffic flows almost continuously in one direction around a central island. Traffic flows in anti-clockwise direction, Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions by reducing traffic speeds and minimizing T-bone and head-on collisions
