Clever intersection design to relieve congestion.

But would it?

Merging traffic always seems to join the "fast" lane, not the "slow" lane - bear in mind it would be mirror image for UK. I guess it might work in heavily congested cities where the difference in lane speed is marginal.

Could anyone justify the extra expense of those link roads just for people who want to go back the way they came?

A conventional roundabout can be used for a "U-turn" if you go wrong - and sometimes necessary if the exit you want from the main road is only possible from the other carriageway.

Drivers would have to learn how to 'weave' or 'merge' pretty smartly on that diagram. I agree too about the built-in U-turn arrangement.

Wouldn't work in the UK, as we have taken the simple and effective idea of roundabouts and ruined them by covering them in traffic lights.

The only good thing about roundabouts with traffic lights on is that usually they are better than what the roundabout was like before the traffic lights were installed. I mean the kind of roundabout where it was virtually impossible to filter into a continuous stream of fast-moving traffic coming from the right.

As for the junction design which this thread is about, I think it would need an enforced 20 mph limit in order to work properly. I also wonder if the designer of it has ever driven a car!
