Crashworthiness and aggressivity ratings for 1982-2000 model vehicles were developed based on data on crashes in Victoria and New South Wales during 1987-2000 and in Queensland and Western Australia during 1991-2000. Crashworthiness and aggressivity were measured by a combination of injury severity (of injured drivers) and injury risk (of drivers involved in crashes). The crashworthiness estimates and their associated confidence limits were sufficiently sensitive that they were able to identify 95 models of passenger cars, four-wheel drive vehicles, passenger vans and light commercial vehicles that have superior or inferior crashworthiness characteristics compared with the average vehicle. Aggressivity rating estimates and their associated confidence limits were sufficiently sensitive that they were able to identify 48 models of passenger cars, four-wheel drive vehicles, passenger vans and light commercial vehicles that have superior or inferior aggressivity characteristics compared with the average vehicle. Trends were examined by year of manufacture both for the fleet as a whole and by market group for vehicles manufactured from 1982 to 2000. (Author/publisher)
