Roundabout Feasibility Study

CRCOG is conducting a Roundabout Feasibility Study throughout the Capitol Region.


  • At CRCOG, we seek to improve intersection traffic safety across our region. As part of this effort, we’ve partnered with Connecticut’s Department of Transportation (CTDOT), and the firm VHB, to study the potential safety benefits of converting existing intersections to single-lane modern roundabouts on our roads in the CRCOG region. We’re conducting a screening study of over 8,000 intersections on state and local roads in the CRCOG region.



Benefits of a Modern Roundabout:

  • Did you know roundabouts are an FHWA-proven safety countermeasure that has been shown to reduce fatal and serious injury crashes by over 75%

    The modern roundabout is an intersection with a circular configuration that safely and efficiently moves traffic. Roundabouts feature channelized, curved approaches that reduce vehicle speed, entry yield control that gives right-of-way to circulating traffic, and counterclockwise flow around a central island that minimizes conflict points. The net result of lower speeds and reduced conflicts at roundabouts is an environment where crashes that cause injury or fatality are substantially reduced.



Regional Impact:

  • At intersections deemed suitable, the conversion of either stop-controlled or signalized intersection to modern roundabouts has the potential to significantly reduce fatal and serious injury crashes. In addition to creating a safer environment for vehicle travel, modern roundabouts are also designed to improve safety for all users, including bikes and pedestrians.
