AbstractProblem and methodThis paper takes a critical look at the present state of bicycle infrastructure treatment safety research, highlighting data needs. Safety literature relating to 22 bicycle treatments is examined, including findings, study methodologies, and data sources used in the studies. Some preliminary conclusions related to research efficacy are drawn from the available data and findings in the research.Results and discussionWhile the current body of bicycle safety literature points toward some defensible conclusions regarding the safety and effectiveness of certain bicycle treatments, such as bike lanes and removal of on-street parking, the vast majority treatments are still in need of rigorous research. Fundamental questions arise regarding appropriate exposure measures, crash measures, and crash data sources.Practical applicationsThis research will aid transportation departments with regard to decisions about bicycle infrastructure and guide future research efforts toward understanding safety impacts of bicycle infrastructure.
HighlightsReviewed safety literature relating to 22 bicycle treatmentsOnly bicycle boulevards and cycle tracks showed a significant decrease in crash risk.Studies on bike lanes and roundabouts conflicted as to change in crash risk.Bicycle safety studies vary greatly in sample sizes, controls, and statistical rigor.Studies suffer from lack of standardized, transferable data on exposure to risk.
