Bicycle lanes: Are we running in circles or cycling in the right direction?

Among nonfatal traffic crash victims, bicyclists experience the highest injury rates behind motorcyclists, and the total estimated cost of bicyclist morbidity and mortality nationally exceeds $4 billion a year. Bicycle lanes, which allow bicyclists to be separated from motorists in order to increase traffic safety. have thus increased in popularity and presence in cities across the United States This article presents findings of a study examining the impact of bicycle lanes on bicycle usage and safety in a major urban city in the United States. The authors hypothesize that bicycle lane construction decreases the incidence and severity of bicycle injuries. They perform a retrospective chart review of 184 consecutive trauma activations due to bicycle-motor vehicle collisions at an urban Level I trauma center in New Orleans, Louisiana. During the study period (January 1, 2007 to January 28, 2017), bicycle use increased almost threefold, and the study findings indicate a higher Glasgow Coma Scale (GCS) score, lower Injury Severity Score (ISS) and decreases in head and face injuries for bicyclists transported to the Level I trauma center. The authors conclude that bicycle lanes function effectively as a protective measure for cyclists and that bicycle lanes support public health interventions.
