Benefits of reducing the age of Australia’s light vehicle fleet

In February 2017, the Australian Automobile Association commissioned Economic Connections (ECON), with Pekol Traffic and Transport and Monash University Accident Research Centre, to undertake an analysis of the road safety and environmental benefits that could accrue from a one year reduction in the average age of the light vehicle fleet, i.e. passenger vehicles and light commercial vehicles and excluding motorcycles. Identification and assessment of policy options to put in place a younger vehicle fleet, including the costs of any options, are outside the study’s scope. The study supports the goals of the association in ensuring that Australian motoring is safe and affordable. It complements a recent study for the AAA, which estimates the cost of road trauma in 2015 to the Australian community and to government (ECON 2017).1 The study methodology is in five parts. Firstly, a future light vehicle fleet is estimated under a ‘business as usual’ case and under two scenarios to achieve the one year average age reduction: a ‘short take up’ (four year phase-in) scenario and a ‘long take up’ (eight year phase-in’) one, with the reduced average age retained for the remainder of a 20 year analysis period. The second and third parts involve estimating quantified road safety impacts and vehicle emissions impacts for the business as usual case and for each scenario. Benefits analysis follows, fourthly, with economic valuation of: the reduction in fatalities, disabilities and other costs (road trauma); avoided mortality and morbidity (pollutant emissions); and avoided climate damage (greenhouse gas emissions). Finally, financial savings to government resulting from these benefits are, where feasible, estimated.
