Mr. John Smith

Job title



Queensland's Department of Transport and Main Roads (TMR), in partnership with the Queensland University of Technology and iMOVE Australia, undertook an evaluation of the safety benefits of a Cooperative Intelligent Transport System (C-ITS) through the Ipswich Connected Vehicle Pilot (ICVP). C-ITS vehicles, roadside infrastructure and cloud services share data, which is used to generate visual and/or audible warnings that are intended to improve a driver’s situational awareness.The ICVP included 355 participants with retrofitted equipment in their vehicles, 29 instrumented traffic-lights and a cloud service covering 300 square kilometres. Based on the driving condition and approaching speed, a driver could experience warnings about red-lights, pedestrians at traffic-lights, roadworks, road hazards, and back-of-queues on motorways. Posted speeds – static, variable, school and roadworks speeds were also displayed throughout the pilot area.Each participant drove for nine months and experienced warnings for six of these months creating treatment and baseline data, while a subgroup formed a control group that were never exposed to the warnings. This enabled the comparison of their driving data with and without the warnings. Three hypotheses were evaluated: lower speed, smoother speed variation and fewer near-crashes.The driving data showed positive safety results, overall, demonstrating improved driver behaviour. Warnings at roadwork, red-lights and pedestrians at traffic-light situations were found to reduce and smooth speeds. From these use cases, assuming 100 per cent penetration of C-ITS in vehicles, the network-wide crash reduction factors were estimated to be up to to 6.8% of fatal crashes and 6.6% of crashes involving serious injuries.
