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…

Signalised interchanges and ramp metering are major components of the interface between the arterial road system and the motorway system. The control systems of motorways and arterials are often treated as separate control components, which can…

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…

The current practice of balancing traffic density or distributing traffic evenly in a road network is essentially subjective and is achieved manually through expert opinions. This report summarises these expert opinions and investigates whether…

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…

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:…
