Cyclist bunch riding: A review of the literature

Monash University Accident Research Centre - Report #285 [2009]

Authors: Marilyn Johnson, Jennie Oxley and Max Cameron

Abstract

This report is a review of the literature on cyclists who ride in large groups or bunches on public roads. The research was conducted following the Victorian State Coroner's investigation into the death of an elderly pedestrian, following a collision with a cyclist who was riding in a bunch. The aims of the review were to understand the behaviour of bunch riders, particularly the behaviours that may contribute to increased risk of collision and to make recommendations for effective enforcement and countermeasure strategies for this road user group. Due to the paucity of published literature on bunch riding, the review was expanded to include other relevant cycling literature. In addition, footage of bunch riding from Victoria Police, recorded in 2005 and 2007 was analysed and the behaviour of cyclists was found to have differed considerably. Based on the findings of this review, some broad suggestions for enforcement and education are made to improve the safety of bunch cyclists. Furthermore, there is a clear need for further research to address the safety concerns of bunch riding and a number of specific research recommendations are made.
