Mini & Modular Roundabouts
WEBINAR: April 28, 2026 - April 29, 2026 , 8:30 AM - 12:00 PM PT
The Federal Highway Administration (FHWA), Caltrans Division of Local Assistance (DLA), Washington State Department of Transportation (WSDOT), and cities of Modesto and San Diego invite you to learn more about the benefits of Mini & Modular Roundabouts.
Hosted by the California LTAP, this 2-day (7-hour) presentation showcases how these roundabout configurations represent a low-cost, quick construction, and traffic calming solution that will be competitive in the upcoming local Highway Safety Improvement Program (HSIP) Cycle 13 call for projects, anticipated in late May or early June of 2026.
Presentation Topics:
- Alignment with Safe Systems & Vision Zero
- Impacts on Fatal & Serious Injury Crashes
- Benefits of Mini & Modular Roundabouts
- Peer Sharing of Local Agencies Experience
- Benefit Cost Ratio (BCR) for HSIP applications
- Considering Roundabouts as a First Alternative

Roundabouts
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.
