The RTA Enhanced Enforcement Program (with publicity) augments traffic enforcement services already provided by the New South Wales Police Service. Enhanced enforcement is designed to coincide with perceived and actual high risk periods on the roads (school holidays and public holiday weekends), and with publicity about enforcement of unsafe road user behaviour. The current decisions about timing, budget, and locations for enforcement appear to be less than optimal and do not necessarily guarantee maximum road safety benefits. The project developed a scientific way to estimate the maximisation of the road safety benefits of enhanced police enforcement for speeding. Given that factors affecting the success of such programs vary constantly, we have used the methods from applied decision analysis coupled with the methods of failure analysis to develop these estimates. This has been translated into formulae that would give us the greatest expected benefit: namely minimising adverse road safety outcomes while minimising expenditures. The results of this study will be presented showing the methods we used to make the best investment decisions from a range of policy options, with the base line option being the usual enforcement of speed limits.
