Riding through red lights: The rate, characteristics and risk factors of non-compliant urban commuter cyclists

This study determined the rate and associated factors of red light infringement among urban commuter cyclists. A cross-sectional observational study was conducted using a covert video camera to record cyclists at 10 sites across metropolitan Melbourne, Australia from October 2008 to April 2009. In total, 4225 cyclists faced a red light and 6.9% were non-compliant. The main predictive factor for infringement was direction of travel, cyclists turning left (traffic travels on the left-side in Australia) had 28.3 times the relative odds of infringement compared to cyclists who continued straight through the intersection. Presence of other road users had a deterrent effect with the odds of infringement lower when a vehicle travelling in the same direction was present (OR = 0.39, 95% CI 0.28–0.53) or when other cyclists were present (OR = 0.26, 95% CI 0.19–0.36). Findings suggest that some cyclists do not perceive turning left against a red signal to be unsafe and the opportunity to ride through the red light during low cross traffic times influences the likelihood of infringement.

Research highlights▶ The majority of Melbourne commuter cyclists observed (93.1%) stopped at the red light. ▶ Direction of travel (turning left) was the main predictive factor for infringement. ▶ Cyclists were less likely to infringe if another road user (driver or cyclist) was present.
