Background Traffic queues at the End of Queue (EOQ) location of roadwork sites are often associated with rear-end crashes, posing risks to roadworkers and motorists alike. To address this important safety issue, Transport for New South Wales (TfNSW) sought to identify and trial effective EOQ treatments in partnership with iMOVE Australia and Deakin University in a research project. This project aimed to improve the safety of roadworkers and motorists at roadworks by developing an evidence base regarding the effectiveness of different traffic management treatments in reducing the frequency and/or severity of injuries associated with EOQ crashes at roadworks. Contribution Best practices in EOQ risk management worldwide were identified through a literature review and consultation with international experts and local industry stakeholders, which provided a list of 25 EOQ treatments for field trials. A total of 33 combinations of these treatments were trialled in 13 worksites of different speed and volume characteristics. Trial data were collected for 116 days using automatic traffic counters for speed data collection, video cameras for near-miss data collection, and roadside surveys with drivers. Data were analysed using statistical ‘before-after evaluation’ methods to examine the effectiveness of the treatments. Significance This research report documents the methodology and findings of the largest roadwork safety trial in Australia. It produced significant new insights for understanding the effectiveness of a range of safety treatments used at roadwork sites, based on which traffic control and management manuals are being updated by the industry.Number of chapters
