Thinking of building a multi-lane roundabout?

Multi-lane roundabouts can be an effective intersection control and reduce injury crashes if the design and layout is carefully considered.

Two LRRB funded studies have recently been conducted to attempt to address these violations. This document is a summary of findings from these studies and local agency experience to date.
