I grew up near a city called Birmingham in the UK which has it's share of... disturbing junctions: https://en.wikipedia.org/wiki/Five_Ways,_Birmingham https://en.wikipedia.org/wiki/Gravelly_Hill_Interchange They look insane on a map, they must have been hellish to navigate before GPS.

Spaghetti junction is still hellish...

It looks like a fairly routine Japanese highway junction though.

When I was visiting the UK, I ended up driving through this intersection a couple of times. It wasn't really a big deal, even for someone not used to roundabouts or driving on the left.

Right - people tell me they find roundabouts really confusing but I say: imagine a one way street, and you're joining it at a T-junction. If you're in the UK the one-way street is going left. If you're in Europe or America it's going right. That's literally all a roundabout is. You can forget about the fact that it's circular. There's no extra rules I believe.

The joining roads in America would probably have "STOP" signs, whereas in Europe it will just be "Give Way"/"Yield", which makes the whole thing run a lot faster.

If it's a multi-lane roundabout, it's important to use the correct lane. Other drivers will expect someone in the appropriate lanes to stay/exit the roundabout accordingly.

The traffic engineer who managed to convince authorities that this was the solution to their problems must've been very charismatic.

Something of a roundabout afficionado it seems [0] ... also ex British Airforce, which given the odd way that the brits assign status, could provide alternative explanations for this madness beyond charisma .... he hadn't even 10 years experience as a working civil engineer when he came up with this.

It was the 1960s. There was a huge push for all sorts of High Modernist experimental (re)design of British towns. Ring roads, tower blocks, roundabout-only layouts like Milton Keynes, brutalist public buildings, all that kind of thing. The country is slowly recovering from this.

If you look at the See Also in the article, you will find 3 other roundabouts of the same name also in the UK, so it seems the country in general has some interesting traffic structures.

What about the fact it has two lanes?

Wow. I googled him a little more, and his story was fascinating.;

> Despite opposition to his concept from many in an engineering profession known for its conservatism, his roundabout designs were formally written into government design manuals in 1975. By this time his experiments had become increasingly radical. Among these were the “magic roundabout” in Swindon in 1972 and multi-ring junction in Hemel Hemp-stead in 1973.

> Such junctions comprising as many as six mini-roundabouts — like a series of cogs in a piece of industrial machinery — did cause some chaos when first encountered by bewildered motorists. But Blackmore proved that the multi-roundabouts reduced speed, increased through-put and aided traffic flow. However, the idea was perhaps one step too far for an incredulous engineering profession, and it never really caught on.

I bought a DEC MicroVAX on ebay a few years ago and the seller lived in Swindon. I passed through the Magic Roundabout on the way there and the way back (during rush hour). Having never encountered anything like it before it was... Well, I'd love to tell you a horror story, but to be honest it was all very logical and flowed very well.

How's is it different to any other road with two lanes?

If you're about to turn off then be on the inside lane. If you're not turning off then be on the outside lane.

They look scarier than they are in practice. What I hate more is those massive roundabouts with traffic lights on where dual carriageways meet. On those things you still have a mix of cars who don't know where they're going and lanes to be away of, but in addition you have traffic lights and cars moving at much higher speeds than on magic roundabouts.

Barcelona. It's fine to have a roundabout where several roads meet, each with multiple lanes, and the circle itself to have 6 or more lanes [1]
