Abstract

Introduction: Cycling offers health and environmental benefits, yet the risk of injury in traffic discourages its uptake, and the safety effects of physically separated bicycle lanes relative to painted lanes or mixed traffic remain contested. Methods: This systematic review followed PRISMA 2020. Scopus, OpenAlex, Crossref, PubMed and Semantic Scholar were searched for comparative studies published between 2013 and 2024. Results: From 714 records, 13 studies were included. Physically separated facilities were associated with lower injury or crash risk than mixed traffic or no facility, with adjusted odds ratios from 0.05 to 0.60, equivalent to 40 to 95 percent lower. Painted lanes showed intermediate risk, and intersections and non-orthogonal geometry were associated with higher risk. Conclusions: Physically separated bicycle lanes are associated with lower cyclist injury risk than painted lanes and mixed traffic. The evidence is observational and heterogeneous, and stronger designs with exposure control are needed.
