    Contribution of structural incompatibility to asymmetrical injury risks in crashes between two passenger vehicles
    (ACRS, 2012) Anderson, R.; Ponte, G.; Australasian College of Road Safety Conference (2012 : Sydney, Australia); Centre for Automotive Safety Research (CASR)
    It is well known that mass ratio affects the probability of injury and death in both vehicles in two-vehicle crashes. Likewise, other evidence suggests that typical 4WD vehicles exhibit poorer than average aggressivity such that occupants of regular vehicles are more likely to be injured in a crash when it involves a 4WD. In this study, the ratio of the incidence of injury and death to drivers in two-vehicle crashes was calculated for crashes with different vehicle mass ratios. Injury ratios were calculated for crashes involving strictly two cars and again for those crashes where the heavier vehicle was a 4WD vehicle (4WD) or a light truck (LT) and the lighter vehicle was a car. There is a common dependence of the injury risk ratio on vehicle mass ratio in both classes of crash, but that there is an additional relative risk to the lighter vehicle driver when the heavier vehicle is a 4WD/LT. The effect is stronger for fatality ratios. Around twice as many drivers are killed per crash in car-to-4WD/LT crashes, indicating that the increased risk to the driver of the car is not completely offset by reduced risks to the driver of the 4WD/LT.

    The use of protective clothing by motorcyclists in Victoria: Evaluation of the Community Policing and Education Project
    (Australasian College of Road Safety, 2012) Baldock, M.; Kloeden, C.; Lydon, M.; Raftery, S.; Grigo, J.; Ponte, G.; Australasian College of Road Safety Conference (2012 : Sydney, Australia); Centre for Automotive Safety Research (CASR)
    The Community Policing and Education Project was launched by VicRoads and Victoria Police in 2009 to reduce the likelihood of motorcycle crashes through a combination of enforcement and education countermeasures. The Centre for Automotive Safety Research at the University of Adelaide was chosen to evaluate the effectiveness of the Project. Methods used to evaluate the Project included a process evaluation, analysis of crash data, on-road speed surveys, an online survey of motorcyclists, and roadside traffic observation. This paper provides an account of the roadside traffic observations, which were focused on helmet use, headlight use, use of protective clothing, and rider conspicuity. The roadside observations in metropolitan Melbourne revealed an apparent effect of the Project, with observed increases in the use of full body protection by motorcyclists following an educational operation targeting commuting riders. Across the three surveys, this proportion increased from 17 (before the operation) to 24 (just after the operation) to 38 per cent (three weeks after the operation). Improvement was most marked among riders of sports and standard/naked motorcycles but is still needed among riders of cruisers and scooters.
