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…

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…

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…

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…

The main purpose of this project was to provide Australasian road safety and enforcement agencies with guidance on appropriate strategies and practices for enforcement programs aimed at speeding in both urban and rural areas, including enforcement…

This report examines sources of information used in establishing a more robust relationship between vehicle speed and accident risk than has been available. This report documents discussions with a supplier of a commercial accident recorder and…
