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…

This report provides a traffic or logical architecture for the new controller. Austroads recognised the need to develop a new generation of traffic signal controllers, making use of modular, scalable design with an open architecture. Two key…

This report includes the examination and recommendation of a five-layer framework to implement controller functions. The key benefit of this concept is the clear demarcation of functions. The proposed concept allows functions to be built logically…

Computer processing power and memory availability have significantly advanced in the last few decades. New concepts in controller architecture and new vehicle detection technologies are now also available. Project NS1377 (Traffic Signal Controllers…

Austroads works towards uniformity of practice in respect of design, construction and user aspects of roads and bridges and with this purpose in view, publishes guides and procedures.

Traffic Engineering Practice, first published in 1965, is a…

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…

A literature review carried out as an earlier stage of this project concluded that there is a dearth of information regarding the basic circumstances of alcohol-affected pedestrian crashes. The present study reports a detailed analysis of crashes…

Drink-driving enforcement is a key component of road safety programs in all jurisdictions in Australasia, with comprehensive enforcement programs that seek both to apprehend offenders and to deter potential offenders. This project was established to…

This report, the primary output from Austroads project N.RS.9810 "Standards for Frangible Sign Supports", aims to present uniform guidelines for the verification of the frangibility of sign post structures utilised within Australia. The document…
