I'm seeing a disheartening growth in interest in #AdvisoryBikeLanes in the US, and am here to caution #cities & #DOTs against them. We already know our #drivers don't respect conventional painted #BikeLanes. It's a bit silly to think they'll know what to do with advisory bike lanes, especially when we install them on #streets built to accommodate #speeding (i.e., nearly every US street).

It's not that #AdvisoryBikeLanes won't work in the US. It's that we won't implement them in a way that would work. Just like so many other #RoadDesign ideas that we try and copy from Europe without actually understanding or definitely not embracing the contexts in which they work.

@DrTCombs we kicked off a research project into them that will tackle some questions of context where they’re appropo and not

@bikepedantic oooooh I'm looking forward to what you find! I would love to see (and experience!) the contexts in which they'd work.

@DrTCombs not ‘me’ directly, but our Fed Lands folks looking at data across existing experiments, and will look at answering questions through future deployment on streets on public lands like the presidio. Unclear how much will be learned, but lots of interest in ensuring that this doesn’t become sharrow 2.0
