On March 4, 2026, Caltrans hosted a free webinar explaining how roundabouts can enhance traffic safety and flow by reducing conflict points and lowering vehicle speeds.

This webinar presented research on roundabout implementation across California, including crash data analysis from the Statewide Integrated Traffic Records System (SWITRS) and public sentiment gathered through surveys and interviews.

Attendees were able to gain insights into roundabout safety performance, community perceptions, and strategies for improving public acceptance, empowering planners, and agencies to better advocate for roundabout projects statewide.
