The human capital approach used by the Bureau of Infrastructure, Transport and Regional Economics (BITRE) to estimate road crash costs in Australia requires rigorous analysis of national road crash data. Such analysis is necessary to determine the internal factors that influence crash variability both spatially and temporally, and the external factors (such as the quality of data) that cause similar variability. The internal factors influencing road crashes relate directly to road users, roads, vehicles and their innumerable interactions. Data analysis to duly recognise the influence of internal factors on the number, severity and probability of occurrence of road crashes is important to those endeavouring to formulate programs and policies to save life and limb. This paper aims to explore trends and probabilities of crash fatalities, hence human productivity and other losses with a view to better inform those formulating road safety programs and policies.
