This report documents a level of service (LOS) framework for network operations from the perspectives of different road users.

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…

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 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…

This project achieved the objective of consolidating the available research on the impacts of lower speed limits on network operations. It extended this knowledge to bridge an identified knowledge gap regarding urban arterial roads by modelling the…

The evaluation of road network operation schemes often requires the use of modelling to forecast the performance of proposals. There is a variety of modelling techniques available, each with its own advantages and disadvantages. Certain modelling…

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…

The increase in the demand for transport services which is forecast to continue into the foreseeable future has placed greater focus on infrastructure and non-infrastructure solutions to meet that demand. Further, there is growing recognition of the…

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…
