20 Percent of Bike Commuters in One Year . . .

Oregon Health Sciences University (OHSU) study that tracked bike commuters and monitored the types and severity of injuries, described in the BikePortland blog. (With a link the published study.) This text got the most interest:

Approximately 20% of bicycle commuters experienced a traumatic event and 5% required medical attention during 1 year of commuting. Traumatic events were not related to rider demographics, safety practices, or experience levels. These results imply that injury prevention should focus on improving the safety of the bicycle commuting environment.
