This report documents the research undertaken for Austroads on bicycle lanes at roundabouts. An extensive literature review informed empirical data gathering.The literature review revealed strong evidence that bicycle lanes on the approach and…

This project examines speeds through intersections. Phase 2 provides an assessment of selected treatments at intersections. A key objective of this research is to provide information to Austroads members on effective techniques to reduce speed and…

Cycling forms an integral element of a transport system, and provides a genuine alternative travel choice to cars while contributing to healthier lifestyles. Many governments, including those in Australia and New Zealand, have set targets to…

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…

Understanding the extent of changes in modal shift and their consequences in terms of road deaths and injuries is essential if we are to fully understand progress towards the targets of the National Road Safety Strategy, and the actions that may be…

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…

Austroads project Classification of motorcycles as a distinct vehicle class aims to test whether motorcycles can be identified as a separate class of vehicle based on distance between axles. Motorcycles are currently classified as light vehicles…

This project had its origins in an earlier project which showed that crash rates increased at extremes of horizontal and vertical geometry, and were lowest with narrow sealed shoulders. This paper reports an investigation based on the original…

The literature has produced mixed results on the effectiveness of red light cameras on crashes. Various Australian studies have shown crash reductions varying from 7% to 46%. Different studies also report different results in the crash types that…

This report investigates casualty cyclist accidents over two years in metropolitan areas of Melbourne and Sydney, and the nature of crashes and intersection features at 18 sites in Melbourne with higher cyclist crash numbers, in an attempt to:…
