Title
Review Educational Presentation on Roundabouts (Discussion Item)
Body
To: Honorable Chair and Members of the Transportation Commission
EXECUTIVE SUMMARY
As part of Vision Zero safety, City staff has contracted with Kittelson consultants to provide expertise and guidance on roundabouts. Modern roundabouts are a type of intersection characterized by a generally circular shape, yield control on entry, and features that create a low-speed environment while traveling counterclockwise around a central island. Modern roundabouts have been demonstrated to provide a number of safety, operational and other benefits when compared to other types of intersections.
BACKGROUND
As part of Vision Zero safety, City staff has contracted with Kittelson consultants to provide expertise and guidance on roundabouts. Kittelson consultants are contracted to provide an educational presentation on roundabouts to the Transportation Commission and the City Council, to identify top locations for potential roundabouts, to peer review the proposed Central Avenue roundabouts and to add policies related to roundabouts in the General Plan update. The work also includes a potential quick build pilot for mini-roundabouts along the City's proposed bicycle boulevards as part of the Action Transportation Plan.
DISCUSSION
Modern roundabouts are a type of intersection characterized by a generally circular shape, yield control on entry, and features that create a low-speed environment while traveling counterclockwise around a central island. Modern roundabouts have been demonstrated to provide a number of safety, operational and other benefits when compared to other types of intersections. On projects that construct new or improved intersections, the modern roundabout should be examined as an alternative. Mini-roundabouts are a type of roundabout characterized by a small diameter and traversable islands, and are best suited to environments where speeds are already low and environ...
