For traffic planners, roundabouts have been huge game changers. Decades of studies show that the introduction of traffic circles greatly improves flow and reduces collisions overall by slowing vehicles down. Another plus is the reduction in greenhouse gases, from fewer idling cars, and increased safety for pedestrians, who have shorter distances to travel. They’re cheaper to maintain than traffic lights and work even during prolonged power outages, such as the kind we experienced recently during Post-Tropical Storm Fiona.
They are kind of similar to their Iceland neighbours I think, who also are full traffic circle
Iceland loves them some traffic circles: easy to maintain as they don’t need power lines digged through the freakin’ basalt. But they have traffic lights too – and even some with heart-shaped indicators. It’s a little quaint; and from my short stays in the country, it just kinda fits.
I absolutely love driving there
