The Austroads Network Operation Planning Framework (the Framework) was developed in 2009 however it is not widely used by road agencies. This research aimed to understand each road agency’s approach and consider how the Framework could be improved…

Congestion in Australian cities has continued to get worse with significant increases in population and new car registrations. About a million new motor vehicles per year were registered in Australia in the years 2005-2007 before the global…

The purpose of the study is to recommend an ongoing Austroads research programme that is focussed on the impacts of the increasing volume of light commercial vehicles (LCVs) and rigid trucks (Rigids) on the urban traffic network in terms of their…

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…

The objective of Austroads Project NS1203 (Estimating Road Network Congestion and Associated Costs) is to develop a procedure to calculate delay and associated congestion costs by making use of directly measurable traffic data. Network performance…

This report provides a literature review on the analyses of the flow breakdown process on a freeway. It begins with the basic freeway flow theory and automatic freeway control tools now in operation. The factors that contribute to flow breakdowns on…

This report reviews the tools that monitor, measure and evaluate the performance of the road network, for both arterials and freeways. The interest in measurement and evaluation tools for the overall network is mainly driven by the need to operate…

This Austroads project was initiated to enable road authorities to develop a better understanding of how various traffic management tools and proposed operational changes to the road network affected the performance of the entire road network, with…

Integrated tools can be a toolbox of technologies and procedures which combine both hard engineering methods such as the use of shoulders and lane access controls as well as dynamic traffic management tools such as ramp meters, incident detection,…

The objective of this report is to identify and document the findings, experiences and issues associated with the application of various road space allocation tools available to road managers. These tools are used to maximise the effectiveness of…
