The Protected Roundabout

Born in Europe decades ago, with a stellar track record for safety and livability, protected intersections have now been installed in Salt Lake City, Utah; Austin, Texas; Chicago, Illinois; and Davis, California. Protected intersections allow for a protected bike lane through the intersection, while mostly separating bicyclists and pedestrians from motor vehicles! Visit protectedintersection.com for more.

We think that modern roundabouts are a fantastic intersection treatment. Now consider what we like to call the "protected roundabout" (previously known as the "Dutch" style roundabout). The protected roundabout concept is the same: a protected bike lane and sidewalk through the intersection with increased safety for bicyclists and pedestrians (and drivers!).

This protected roundabout continues the protected bike lanes right through the intersection. bicyclists cross the side street (see to the right of white suv, right side) on their own path adjacent to yet separated from pedestrians.

PROTECTED ROUNDABOUT DESIGN GUIDANCE

THE MASSACHUSETTS DEPARTMENT OF TRANSPORTATION CREATED A DESIGN GUIDE THAT INCLUDES GUIDANCE ON ROUNDABOUTS WITH SEPARATED BIKE LANES (THIS IS PAGE 76 OF CHAPTER 4: INTERSECTION DESIGN): https://www.massdot.state.ma.us/Portals/8/docs/SBLG/Chapter4_Intersections.pdf
