So I heard you like odd roundabouts. https://goo.gl/maps/SujbM Junction 8/8a on the M11 in the UK. The roundabout-with-extra-loop actually works pretty well - it's mostly three lane with traffic lights and a hint of turbineness about it. It handles all traffic to/from the north, and all traffic to/from the south with the sole exception of traffic between the M11 to/from the south and the A120 and the airport to the east. The extra bit of the roundabout provides a shortcut for traffic from the north heading west, and traffic from the west heading south - both significant flows. Junction 8a is the extra pair of sliproads to/from the south feeding directly into the A120 to the east (and thence to/from the fourth largest airport in the UK). To the south the M11 is three lanes each way; to the north it's two. The paired sliproads to the south actually start a mile and a half south of the roundabout. I suspect this might horrify people in the USA, but I've never witnessed an accident here.

Hippie Hedgehog posted:OK, traffic talk. You only get a green if that section of pedestrian crossing is fully protected. Otherwise, you don't. A green light when cars are still able to cross seems a very bad idea, to me. There's no such thing as jaywalking in the UK - if you think it's safe to cross without waiting for the lights, then by all means do so.

Jonnty posted:You see a similar design to that junction above in the UK on non-motorway dual carriageway. The speed limit is still normally 70mph though, just like on motorways. There are also many similar junctions on the A1. Some have been closed or rebuilt - the Elkesley accident reduction scheme has been in progress for several years, for example - but there's plenty left. And the A1 is by no means a minor road. There's still at few on the A14 I think, and there's definitely some on the dual carriageway sections of the A66.
