Bike Lanes and Bike Accident Severity

A recent study by researchers from University at Buffalo, The State University of New York has demonstrated that the availability of dedicated bike lanes is not the primary factor in the severity of bicycle accidents. The study used 2010 bicycling injury data from NHTSA. The researchers' analysis found that factors including use of alcohol by either driver or bicyclist, riding after dark with or without street lights, helmet use, weather, and speed were more important factors in determining the severity of accidents. There are previous studies, some published over 30 years ago, indicating that the use of dedicated bike lanes reduces the frequency of accidents.
