Communities are challenged to provide transportation systems that enable traffic to flow efficiently and safely. Whether it is a new roadway or improvements to an existing corridor, each location is unique, so determining the best options for transportation solutions depends on a wide range of variables. These can include site challenges, volume of traffic and mix of users, including pedestrians and bicyclists.

Roundabouts meet the demands of both the traveling public and local communities for safe, efficient traffic flow. They can be used to address issues of safety, speeding, aesthetics, access, site distance, sustainability, capacity, signal not warranted or a combination of these factors. Design of a roundabout starts with identifying and understanding these problems and creating a solution that meets the community’s needs. A well-designed roundabout can turn even a reluctant user into a fan.

The installation of a well-designed roundabout can:

  • Keep traffic moving efficiently; reducing delays specifically during the non-peak hours.
  • Increase safety. With reduced speeds, a 90% fatal crash reduction has been documented by the Federal Highway Administration.
  • Provide a refuge for pedestrians and bicyclists to traverse intersections safely.
  • Create aesthetically pleasing intersections that can be used as a gateway to a community or to beautify a campus roadway network.
