This paper was previously published in Monash University Accident Research Centre (MUARC) Report 228, and for the abstract see ITRD E211743. This report describes the results of research to develop and apply a comprehensive model to consider the influence of the mix of vehicle types on the total safety of the light passenger vehicle fleet in Australia. Key inputs to the model are estimates of the crashworthiness and aggressivity of light passenger vehicles in the key crash types representing the majority of crashes in which these vehicles are involved. By varying the key parameters of the model, it was possible to examine the effects on the average safety of the light vehicle fleet resulting from changes to the mix of types of vehicles in the fleet. Application of the model was demonstrated through a number of scenarios varying the mix of vehicles in the fleet by broad market group classification. Results of applying the model to the various scenarios considered point to how the vehicle fleet mix might best be manipulated in the future to optimise safety outcomes. Safety outcomes resulting from recent current and projected future trends in vehicle fleet mix were also able to be quantified. (Author/publisher)
