Road Safety Engineering Risk Assessment Part 6: Crash Reduction Rates

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…

Road Safety on Local Government Roads: Final Report

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…

Road Safety Engineering Risk Assessment Part 5: Review of Crashes on Unsealed Roads

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…

Road Safety Engineering Risk Assessment Part 2: Crash Risk Migration

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…

Road Safety Engineering Risk Assessment Part 1: Relationships between Crash Risk and the Standards of Geometric Design Elements

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…

Improving Local Road Expenditure Data Provision

Local road expenditure data is collected and reported by the Australia Bureau of Statistics and used by the National Transport Commission (NTC) in its heavy vehicle charging methodology. This project is to improve local road expenditure data to…

The Crash and Offence of Newly Licensed Young Drivers
South Australian drivers who obtained their first provisional car licence between July 1998 and June 2001 and who were 16 to 19 years of age at the time of provisional license issue were identified. Their involvement as car drivers in crashes in…
Heavy Vehicle Safety in Rural and Remote Areas

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…

Component Costs in Transport Projects to Ensure the Appropriate Valuing of Safety Effects
Austroads commissioned ARRB to consider the current costing procedures used in determining the relative cost share of safety in project evaluation. Australia currently uses a human capital approach to the valuation of crash costs, while many other…
Road Surface Characteristics and Crash Occurrence: A Literature Review

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…
