The data has been trickling in for years in Powerpoint slides and stray tweets: on one street after another, even in the bike-skeptical United States, adding a physical barrier between bikes and cars leads to a spike in bike traffic.

The bike spike showed up at every single facility measured, even those that previously had conventional painted bike lanes.
