First US study on segregated bike infrastructure
US and Canadian studies show benefits of segregated bile infrastructure.
And for those who lament this "division" I suggest spending a week (or a winter) in Girona, Spain and see how a very cycling-oriented city deals with this.
Forget the Netherlands for a moment - Girona is a very cycle-friendly city (and area) with many pro teams training, plus your regular casual bikers. It all seems to work well (except for the occasional idiot on all sides).
"Today, Portland State University's National Institute of Transportation and Communities released its voluminous findings from a wide-ranging study of protected bike lane intersections in five U.S. cities. It's based on 204 hours of video footage that captured the movement patterns of 16,000 people on bicycles and 20,000 turning cars; on 2,301 surveys with people who live near the projects; and on 1,111 surveys of people using the protected lanes.
"This has never been done on this scale — having five cities and a number of different sites being done at the same time," NITC spokesman Justin Carinci said in an interview Monday. "The number of hours of video review is unprecedented. But the perceptions piece is really the most definitive of it: This is a big enough sample that we could say for each of the (projects), people feel safe riding them. People say we should have more of them."
