The aim of this project is to investigate intersection crashes with a view to determining suitable intersection approach treatments, and opportunities for better managing speeds through intersections, so as to reduce the severity of intersection…

This study compares and examines the performance of micro-modelling (SIDRA) and microsimulation (AIMSUN, VISSIM and Q-PARAMICS) in modelling of single signalised intersections. The aim is to contribute to the Austroads NS1371 guidelines by improving…

Intersection crashes are one of the more common type of crash that may occur in rural environments. It is therefore important, within a Safe System, that factors that may contribute to intersection crashes and methods that may be used to prevent…

Roadside hazards pose a major risk to road users who lose control of their vehicles and run off the road. From 2003 to 2007, an average of 558 fatal run-off-road crashes occurred annually in Australia and 135 in New Zealand. In addition to these,…

The motor car currently dominates personal travel. However its position is being challenged by concerns over congestion, fuel availability and price, local air quality and global atmospheric impacts. While public transport will be called on to play…

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…

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…
