This study describes the calculation of updated ratings that measure the relative safety of vehicles in preventing severe injury to people involved in crashes. Three different aspects of secondary safety are examined: crashworthiness which focuses on drivers of the rated vehicle, aggressivity which focuses on drivers of other vehicles and unprotected road users such as pedestrians, cyclists and motorcyclists colliding with the rated vehicle and total secondary safety which examines the combined crashworthiness and aggressivity performance of the rated vehicle. Updated ratings for 1982-2013 model vehicles were estimated based on data on crashes in Victoria and New South Wales during 1987-2013, in Queensland, Western Australia and New Zealand during 1991-2013 and in South Australia during 1995-2013. Each rating is measured as a combination of injury severity (the risk of death or serious injury given an injury was sustained) and injury risk (the risk of injury given crash involvement). The ratings were adjusted for the sex and age of the person whose injury outcome was being measured, speed limit at the crash location, number of vehicles, crash configuration and type or road user involved where relevant, the jurisdiction in which the crash occurred and the year in which the crash occurred. These factors were strongly related to the risk of an injury being sustained in the crash and the likelihood of injuries sustained being severe. Each rating estimates the risk of being killed or admitted to hospital when involved in a crash, to a degree of accuracy represented by the confidence limits of the rating in each case. Crashworthiness estimates and their associated confidence limits were obtained for 585 vehicle models classified into 10 market groups. Aggressivity rating estimates and their associated confidence limits were obtained for 516 vehicle models. The total secondary safety index estimates and their associated confidence limits were obtained for 646 vehicle models classified into 10 market groups. A method ...
