isn't the entire reason behind using roundabouts to prevent adding traffic light?

Yes, however for some reason councils in the united kingdom love mixing the two. For NO purpose what therefore ever. It adds sound and pollution, decreases traffic down and completely defeats the purpose of it Regular roundabouts are good at numerous junctions they permit traffic to move freely when there is room with a pleasant easy giveway program. They keep traffic moving and are miles much better than traffic lights. One or another perhaps not both -_- Actually easy to use only give way to people on the roundabout, when theres room combine in and then bypass before you want to get down. Whats the purpose in attaching a traffic light on a thing that did so well for many years have we become retarded starightaway?
