Roundabouts are rare in the US (where they are called traffic circles), with traffic authorities favoring stop signs instead. Last year ago, I wrote about the so-called ‘magic roundabout’ in Swindon, UK that contains seven roundabouts looks incredibly complicated but apparently moves traffic through it very quickly and efficiently. In that post, I provided the graphic below but it does not fully capture the experience.
Andrea James says that roundabouts are better than stop signs and provides video of the actual traffic flow in the Swindon roundabout, that has seen only one fatal accident in the last five years.
But for the person navigating it for the first time, it may be a bit confusing as this video of two Finnish tourists narrating their experience suggests.
