Roundabouts reduce the severity of crashes at intersections, but transportation agencies have received some feedback from pedestrians indicating that roundabouts, especially larger multi-lane roundabouts, can be difficult to navigate.
Roundabouts continue to be installed on state and local roads in Minnesota—as well as the United States. They have gained popularity for their ability to increase safety and efficiency of vehicle traffic. It has also been found that roundabouts reduce pedestrian related crashes.
However, there have been conflicting observations about pedestrian user experience pertaining to clarity, visibility, access, safety, and delays.
The professional community and transportation agencies want to understand pedestrian behavior, pedestrian treatments for improving visibility of pedestrians and behavior of drivers, guidance with regard to pedestrian treatments, and best practices to follow when evaluating roundabouts for pedestrian user experience.
In a new project, researchers will look at pedestrian safety data, best practices for pedestrian features at roundabouts, and features that can be implemented to help pedestrians be seen, noticed, and yielded to.
The project team will develop a guidebook and decision tools for improved designs and controls for current and future roundabouts. These resources will be geared toward MnDOT, cities, and counties.
