This project forms part of a major Austroads strategic research program to improve the understanding of the relationships between crash risk, road infrastructure and traffic operations. A crash rates database was created for all Australian…
ARRB Group has completed a major Austroads research program to assess risk involving road, traffic and roadside infrastructure. The results provide road authorities with more effective tools to reduce road crashes and injuries. The objectives for…
Local government roads form a significant part of the public road network, but little is known about crashes on these types of roads. This study involved a review of literature, crash data analysis, site investigations, in-depth crash analysis and…
A large proportion of the road network in Australia and New Zealand is unsealed (58% in Australia, 36% in New Zealand). It is important to understand what factors lead to the occurrence of crashes in this environment, and what measures may be…
This report provides an overview of the effect known as crash risk migration (CRM). It is intended to build an understanding of the potential for CRM to occur as a result of road safety treatments. It is also intended to inform current approaches to…
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…
Road safety in rural and remote areas of Australia and New Zealand continues to be a major area of concern. Analysis of crash data also shows that a substantial proportion of crashes in these areas involve heavy vehicles. On average there have been…
The starting point for this review was the recently-published Austroads Guidelines for the Management of Road Surface Skid Resistance. Skid resistance, which depends on both microtexture and macrotexture, is currently the road surface characteristic…
