This report provides a compendium of recent and robust evidence on the relationships between twenty key geometric design criteria and safety outcomes.
The project critically reviewed quality research sources to identify crash modification factors…
This report draws on literature and crash data analysis to identify and quantify geometric road design elements which contribute to casualty crash occurrence and severity on rural roads, e.g. lack of sealed shoulders, steep downhill grades combined…
This project achieved the objective of consolidating the available research on the impacts of lower speed limits on network operations. It extended this knowledge to bridge an identified knowledge gap regarding urban arterial roads by modelling the…
This project forms part of an ongoing Austroads strategic research program to improve the understanding of the relationship between crash risk and road elements. This report provides a summary of the relationship between crash risk, and geometric…
