As Cities Add Bike Lanes, More People Bike and Biking Gets Safer

From http://usa.streetsblog.org/2016/07/20/report-as-cities-add-bike-lan...

In five of the cities — Chicago, Minneapolis, New York, Philadelphia, and Portland — the absolute number of cycling deaths and severe injuries fell between 2007 and 2014, even as cycling rose substantially. In the two other cities — San Francisco and Washington, D.C. — deaths and serious injuries increased somewhat, but not as much as the increase in bicycle commuting.
