Reckless cyclists or impatient drivers? A naturalistic study of group riding in Perth, Western Australia
This study aimed to describe the unsafe events and road rule violations observed among groups of riders in Perth, WA using naturalistic video and GPS data. A total of 72.5 hours of eligible naturalistic group riding video footage recorded from cameras mounted on bicycles were analysed. Common violations were stop sign violations and riding more than two abreast. For unsafe events, 65% of the events involved an interaction with a motor vehicle, with over half of these involving unsafe overtaking manoeuvres (58%). Recommendations include motorist education as well as considering the safety needs of group riders in road infrastructure design.
