It's called a roundabout. ;-) http://en.wikipedia.org/wiki/Roundabout http://en.wikipedia.org/wiki/Roundabout They help traffic flow lots in the UK and elsewhere around the world. Not a panacea though.
- mrduncan 17y agoI've never seen a roundabout work well with high traffic though (in the US anyway), it has always seemed to me that they work amazingly well with low and medium traffic, but once they are full you end up with a single inbound street hogging it since everyone else has to yield.
- kchecker 17y agoWell you can have roundabouts with traffic lights. They work well in Chandigarh, India.
- ralph 17y agoEveryone else would have to yield only if all traffic entering from that single busy inbound road was going all the way around the roundabout and exited onto the road it entered from. Since few cars do this, the odd single car on other entrances gets a gap where they pull out, often causing the busy road to queue while they pass, which in turn lets others out, etc. I agree though, the heavier the traffic the less they work. Especially when morons pull out onto it despite seeing the exit is jammed and without leaving room for other lanes to cross in front and behind of them. Also, in the UK, many drivers fail to signal correctly, giving less clues to other drivers as to when they can pull out, e.g. if you're not signalling left as you exit a roundabout, you're doing it wrong! :-)
