Interest in the application of macroscopic models for the description of improvements in traffic safety has increased since the early 1980s.
Two models that have been developed to establish relationships between traffic volumes and traffic safety (based on fatality rates) are applied to New Zealand and Australian data to compare these countries' developments in traffic safety to those of six other countries. Up till 1991 performance in reducing fatality rates was relatively poor in New Zealand and good in Australia.
Since 1991, when the modelling and comparisons with other countries were performed, progress in reducing the fatality rates in both New Zealand and Australia has been good.
