Driving in circles can be a good thing, if it means you get where you want to go quicker and safer. That’s why the Missouri Department of Transportation is using roundabouts as a way to manage traffic at some intersections. The video below will help you better understand how to navigate a roundabout, plus explain the many benefits they have compared to traditional traffic signal intersections.
A roundabout is a one-way circular intersection that channels traffic around a central island without traffic signals. Roundabouts are a great alternative to a signalized intersection when a high volume of traffic needs to get through with the least amount of inconvenience.
While signalized intersections have approximately 20-30 conflict points, or spots where vehicles could collide, roundabouts reduce that number to eight. Fewer conflict points, combined with slower speeds and calmer traffic, can translate into as much as 76% fewer crashes. Because roundabouts tend to have fewer severe crashes than signalized intersections, they have fewer crash-related injuries as well. View the Roundabout Handout to learn more.
