Official bike crash reports account for 30-40% of all incidents. We used Arizona Department of Transportation (ADOT) bike crash data from 2009 to 2015 to map the 12 worst spots for bicycling in Tempe. But, there is a lot we still don’t know. Inform policy makers, advocates, and researchers about bicycling safety in your city! Map bicycling crashes, near misses, and hazards at BikeMaps.org.
