10 Jul 20 - 06:45 AM (#4063622) Subject: RE: BS: Crazy road junction - safer & better!! From: Steve Shaw There's a similar magic roundabout at the Plough junction in Hemel Hempstead. We have two very vexatious double roundabouts in Launceston and a couple of very tricky ones in Truro. I heard recently that it's illegal to drive over the middle of a mini-roundabout. That makes me a serial criminal. |

From: DaveRo I used often to use the Hemel Hempstead Magic Roundabout, which is essentially the same as the Swindon one, and it works very well. It used to be six mini-roundabouts - against Swindon's five - but one road was closed to traffic a couple of years ago. The first magic roundabout I met was at Colchester. They were experimenting, and laid it out with white-painted tyres. I went there every couple of months and every time it was different, until it settled down to the concept later followed in Swindon. Hemel also had a wonderful twin spiral multi-storey car park - one spiral up, one down, with level links between them across the middle (like the staircases at Chambord). |

I grew up driving in Massachusetts and adopted the standard Boston entry to what we called 'su-kills' (Circles). Accelerate while crossing yourself! Alaska has installed roundabouts in several locations and they seem to improve matters so long as you can maintain your traction during icy conditions. |

While watching it I just have to do a bit of mental gymnastics to translate it into driving on the left and not the right. Our problem in Oz even with simple, single circle roundabouts is that a significant chunk of drivers don't bother sticking to the speed limit, don't give way to vehicles already on the roundabout, don't use their indicator to tell the rest of us where they are going & when they are leaving the roundabout, and often have an aggressive attitude to any other vehicles which have the hide to get in their way. Quite often they are driving 4WD utes or 4WD Balmain Shopping Trolleys (great big clean and shiny 4WD's which have never seen a dirt road, driven by people who just use them to buy groceries or ferry the kids to school). |

D.C. yes, there are 10 streets to consider when deciding whether to go to the inner or outer circle. Also, pedestrians do random things and most taxi drivers assume they have eternal right-of way. |

11 Jul 20 - 12:07 PM (#4063757) Subject: RE: BS: Crazy road junction - safer & better!! From: gillymor Yeah Bill, I grew up in the D.C. area and worked right off Dupont Circle for awhile and that whole town is full of them and they added a bit of tension to your commute but then I went to Rwanda in 2005 and encountered this in Kigali, the captial. At rush hour it was just a free for all with no visible lanes and motorbikes and cycles weaving in and out like daredevils and participants in freshly sustained collisions arguing out in the middle of traffic. I was happy to get out in the countryside. |

The choice of location wasn't the best and it's (in my opinion) poorly designed*. In four or five years it will be ripped out and replaced with whatever the highway engineering fad is at that time. *That could also be due to placement -- at an Interstate entrance/exit ramp with at least three side streets with stop lights feeding into the "divisive diamond." |

From: Mr Red The Kigali link does not work But I assume this is the roundabout. what3words.com/shatters.dive.stretch We had a spread out 6-way junction near where I lived at the time that had so many islands we called it the Silly Isles. It is traffic lights now. what3words.com/recent.layers.defeat |
