A large number of larger roundabouts in the UK have traffic lights at the entrances and exits. What do you find idiotic about it? Works extremely well to keep traffic flowing.
- iwr 16y agoLights by their design will stop traffic and reduce road capacity (they are ostensibly for safety rather than road use). The point about a roundabout was to keep traffic moving, not stop it. If there are lights, there is no difference between a roundabout and a circular intersection.
- axod 16y agoNot really, the lights on large roundabouts are pretty dynamic. You have lights to stop people going further round the roundabout, coupled with lights to stop people coming on to the roundabout. But traffic flow is pretty continuous. When setup well, it couples the good points of a roundabout with the good points of a basic intersection. They're usually seen though where you have maybe 7 or 8 roads coming together. If you didn't have stop lights, people from the smaller roads would never be able to enter the roundabout.
