Posted: 5/22/2024

WEBINAR: May 29, 2024, 9:00AM - 11:00AM PT [CLOSED]

Affordable Compact and Mini-Roundabouts are being implemented by state and local public agencies due to their low cost, quick delivery, reduced vehicle speeds, and ability to prevent up to 90% of severe crashes.

Join us for this free 2-hour webinar to hear first-hand about Affordable and Modular Roundabouts from the Washington Department of Transportation, the City of San Diego, and our own Caltrans intersection and safety experts.

This Webinar Will Cover

  • Characteristics of Affordable Roundabouts and how they have been proven to be as effective as full roundabouts.

  • Success stories from state/local public agencies who have installed Affordable Roundabouts.

  • How the emergence of Modular Roundabouts featuring fabricated components make it possible to install small roundabouts in several days at a fraction of the cost.

A 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 provide a 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.
