In Swinson, England, this 7 circle roundabout has been used for more than 60 years to optimize multi-directional traffic flow at intersections. Instead of the typical roundabout that moves in one direction, this roundabout offers drivers the chance to go clockwise or counterclockwise to reach their desired destination. Entering the roundabout from one of five points, drivers can make their way to the exit of their choice in a direct manner, simply yielding to other drivers ahead of them. A mathematical and design beauty, it is a wonder that this isn’t common around the world.
