From the Star Tribune:
Recently crunched city data show the reported cyclist-motorist accident rate dropping as the number of bike commuters grows. For 2008, the most recent year for which complete data were available, the crash rate was one-quarter that of 10 years earlier. Moreover, a trend line shows a steady decrease in the crash rate even as the number of commuting cyclists more than doubled.
It would be interesting to see these crash rates for other cities, since we know mode share for bicycles is increasing in many parts of the metro. I’m not sure if they parse them out as specifically as Minneapolis does.
The Strib also quotes Peter Jacobsen from the journal Injury Prevention, but leaves out a critical sentence (emphasis mine):
A motorist is less likely to collide with a person walking and bicycling if more people walk or bicycle. Policies that increase the numbers of people walking and bicycling appear to be an effective route to improving the safety of people walking and bicycling.
About a month ago, the Governors Highway Safety Association released a report that actually said “A focus on liveable communities…may increase walking and pedestrian vehicle conflicts”, although the discussion in the report actually seems to point more towards distracted pedestrians or pedestrians being forced to walk were poor or no facilities existed.
