#Damien Talks Episode 13 – The Davis Planning Department on the Bike Protected Intersection

Hard to explain; simple to use. Image via ##http://usa.streetsblog.org/2015/08/11/it-just-works-davis-quietly-debuts-americas-first-protected-intersection/##Streetsblog USA.##

Today, #DamienTalks with Jennifer D’Onofrio and Bryan Michaelson of the City of Davis about the new protected bike intersection in Davis, California. The newly redesigned intersection is the first of its kind in America, and receiving warm reviews from both cars and bicyclists in Davis and advocates around the country.

As you’ll see in the middle of the episode, it gets a little complicated trying to explain how the intersection works. D’Onofrio and Michaelson assure me that it’s pretty simple when you’re actually riding in the street…an opinion shared by my colleague Michael Anderson who wrote of the intersection, “hard to explain, simple to use.”

If you have trouble following it, check out Anderson’s post, and pictures, at Streetsblog USA.

We’re always looking for sponsors, show ideas, and feedback. You can contact me at damien@streetsblog.org, at twitter @damientypes, online at Streetsblog California or on Facebook at StreetsblogCA.

Thanks for listening. You can download the episode at the Damien Talks homepage on Libsyn.

  1. I’ve added in some notes on top of Davis’s more technical rendering of the intersection as I understand it to work:



    Class I = shared two-way multiuse path (bikes, peds, etc.)
    Class II = conventional one-way on-road bike lane
    Optional Diverter Channel = optional connection between Class I and II

    Again, this is how I currently understand the intersection to work. Will confirm once I check it out this weekend 🙂

  2. Thanks for posting the interview! Great to hear about the positive response it’s been getting in the community. That comment about even kids instinctively getting it and using it unsupervised is directly analogous to how good 8-to-80 infrastructure like this works in the Netherlands:


    Damien, maybe part of the totally understandable armchair confusion over this intersection in Davis is that it has both:

    1) buffered on-street bike lanes


    2) separated multiuse pathways (what Caltrans calls Class I multiuse paths for people on foot, bike, rollerblades, wheelchair, etc.–and as with all such paths these are wide and bidirectional, by the way)

    It is the latter that receives the protected intersection, not the former. This is a distinguishing characteristic from Dutch intersections which would not have both a separated and on-road lane for people biking to choose from in the same corridor. However, this is a fairly common thing in Davis so locals should be pretty used to the option.

    Interestingly Davis has *also* built an optional “onramp” channel into the protected intersection from the on-street bike lanes if people wish to bike on-road mid-block but then join the protected path at the intersection.

    Or, they can just stay on the Class I the whole time.

    Or they can bike on the road the whole time and do vehicular turns.

    I’ll try and take some pics of it this weekend when I go.

America Could Have Been Building Protected Bike Lanes for the Last 40 Years

Salt Lake City is on track to implement the nation’s first “protected intersection” — a Dutch-inspired design to minimize conflicts between cyclists and drivers at crossings. For American cities, this treatment feels like the cutting edge, but a look back at the history of bike planning in the United States reveals that even here, this idea is far from new. In fact, […]

Four Cities Race to Finish the Country’s First Protected Intersection

Michael Andersen blogs for The Green Lane Project, a PeopleForBikes program that helps U.S. cities build better bike lanes to create low-stress streets. Sometimes, change builds up for years. And sometimes, it bursts. Fifteen months after American bikeway designer Nick Falbo coined the phrase “protected intersection” to refer to a Dutch-style intersection between two streets […]
