Best Practice for Variable Speed Limits: Best Practice Recommendations
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…
Best Practice for Variable Speed Limits: Literature Review
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…
Best Practice for Variable Speed Limits: User Perception and Comprehensive Study
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…
Development of a Best Practice Intervention Model for Recidivist Speeding Offenders

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…

Impact of LATM Treatments on Speed and Safety
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-…
Guide to Road Safety Part 3: Speed Limits and Speed Management
The purpose of this guide is to provide an overview of speed limits and their application as a speed management tool. The use of appropriate speed limits form an integral part of a safe road system. They are a speed management tool used to improve…
Evaluation of Speed Limiting Locally Operating Warning Signs
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…
Balance between Harm Reduction and Mobility in Setting Speed Limits: A Feasibility Study
This project has been funded by Austroads to develop, trial and evaluate a new system for setting speed limits based on harm reduction principles. This first, feasibility stage of the project has consisted of three main tasks: a literature review…
Heavy Vehicle Compliance with Speed and Mass Limits: Evidence from Weigh-in-Motion Devices
This project has involved the collection into a single database of all available WIM data and the interrogation of that database to provide information on speed and mass compliance by two selected vehicle types Results of this work must be treated…
A Review of Literature and Trials of Intelligent Speed Adaptation Devices for Light and Heavy Vehicles
The implementation of Intelligent Speed Adaptation (ISA) has the potential to significantly reduce the incidence and severity of road trauma in Australia and overseas. This report reviews the available literature and trials involving ISA from…
