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 objective of this project was to provide advice to jurisdictions on appropriate speed limit setting policy in light of harm minimisation (the Safe System approach). This advice was based on the improved understanding of the relationships between…

Austroads project NS1378 Best Practice for Variable Speed Limits (VSL) aims to review international and domestic VSL initiatives, recommend methods to achieve best practices in VSL design and operational issues, propose a consistent appearance so…

This report aims to produce best practice recommendations as a basis for consistent application of variable speed limits in Australasia. VSL have been trialled since 1960s in the US and European countries. In Australasia, the first VSL trial started…

Austroads project NS1378 Best Practice for Variable Speed Limits (VSL) aims to review both international and domestic VSL initiatives, recommend methods to achieve best practice in VSL design and operational issues, propose a consistent appearance…

Speed-related crashes are a continuing concern in Australasia. On behalf of Austroads, ARRB Group undertook to develop a framework for an intervention to promote safe driving among recidivist speeders.

Five key tasks were carried out: a literature…

The aim of this project was to establish the effectiveness of key Local Area Traffic Management (LATM) treatment types in reducing traffic speeds and in reducing the risk of crashes on local roads in Australia. A review of recent literature (post-…

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 study investigated the efficacy of Speed Limiting Locally Operating Warning Signs (SLLOWS) at a number of sites in the Perth metropolitan area. It was found that SLLOWS were successful in reducing vehicle speed at all locations (3-4 km/h on…
