This study aimed to identify risk factors for collisions and near-collisions involving on-road commuter cyclists and drivers.

A naturalistic cycling study was conducted in Melbourne, Australia, with cyclists wearing helmet-mounted video cameras. Video recordings captured cyclists’ perspective of the road and traffic behaviours including head checks, reactions and manoeuvres. Participants were adult cyclists and each filmed 12 hours of commuter cycling trips over a 4-week period.

In total, 127 hours and 38 minutes were analysed for 13 participants, 54 events were identified: 2 collisions, 6 near-collisions and 46 incidents. Prior to events, 88.9% of cyclists travelled in a safe/legal manner. Sideswipe was the most frequent event type (40.7%). Most events occurred at an intersection/intersection-related location (70.3%). The vehicle driver was judged at fault in the majority of events (87.0%) and no post-event driver reaction was observed (83.3%).

This study will be extremely useful for local governments in understanding the risks faced by cyclists in sharing the roads, the causes of these, and potential solutions to ensure cycling remains safe and accessible for your residents. The full details can be found in the attached document.
