Road diet safety: an Australian viewpoint

Urban arterial roads are characterised by a high number of crashes, including those that result in fatalities and serious injuries. Of concern on these roads is managing or improving safety while maintaining efficiency/throughput and access. One of the treatments aimed at improving road safety while maintaining access and efficiency is the implementation of road diets (typically involving the conversion of arterials with two lanes in each direction to one lane in each direction with a central turning lane). This treatment has been extensively applied across the United States with limited use in Australia and New Zealand. An evaluation of crashes and speeds before and after the installation of road diets was conducted. The evaluation included a comparison group to account for the underlying trends at the different locations. The evaluation was aimed at determining the treatment’s effectiveness in an Australian context. Results on estimated crash and speed reductions are presented. These were compared to those in existing literature.
