This project aims to review current technologies and techniques for automatic freeway incident detection (AFID) and to provide guidance on the deployment of AFID applications, focusing on the operational aspects of incident detection. The focus is…

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…

The Austroads Improving Traffic Incident Management project involves a review of traffic incident management in major urban regions across Australia and New Zealand. This report provides a brief overview of all aspects of traffic incident management,…

This report reviewed current traffic incident management practices in Sydney, Melbourne, Brisbane, Adelaide and Perth, to identify successful practices and challenges or gaps in current practices that could lead to improvements in the management of…

This study reviews recent developments in road pricing for managing road travel demand and congestion, and identifies potential pricing mechanisms to facilitate freight modal choice based on marginal social costs including environmental and other…

This report provides an analysis of road pricing from a technical perspective to inform road authorities in Australia and New Zealand of some of the key issues involved. A key objective is to provide advice on what is required to identify and…

This report investigates the appropriateness of microsimulation modelling for the planning, operation and training of incident management in a road network. The methodology for this study includes a literature review and a modelling case study of…

It could be argued that literature on traffic incident management seemed to fall into two categories
