Philadelphia Parking Separated Bike Lane Study

Parking separated bike lanes (PSBLs) are in-street bikeways that are separated from moving motor vehicle traffic by a parking lane and a buffer area…

In the City’s study, safety data from peer cities were reviewed to evaluate the effectiveness of PSBLs. Many of the reviewed case studies found that the installation of PSBLs reduce crash rates for motor vehicle drivers, bicyclists, and pedestrians, especially at mid-block locations where crash injuries tend to be most severe. PSBLs were also found to reduce people biking on the sidewalk, lower vehicle speeds, reduce interaction between people driving and bicycling, and eliminate the risk of side swiping or overtaking people bicycling. Crashes involving a driver overtaking a person bicycling are the leading cause of fatalities for people bicycling in the US.
