This report clarified the logical architecture required to facilitate the implementation of ‘plug-in’ traffic control software, as an alternative to the control algorithm in the current controller software. The key functional requirements of an…

This report documented current activities amongst road agencies in Australia on the SCATS/STREAMS interface through the SCATS Intelligent Transport System (ITS) Port, and identified a set of 26 functional requirements for this interface to guide the…

This report has developed a new index, the Heavy Vehicle Roughness Band Index (HVRBI), as a measure of ride quality for heavy vehicles. The HVRBI is intended for use by road asset managers as a trigger to initiate pavement intervention works…

This study obtained an indication of the proportion of Australian commercially manufactured polymer modified binders (PMBs) liable to segregate, identifed suitable tests to measure segregation propensity and proposes measures to help prevent or…

This report is an investigation on the development of the performance relationships used in the 2002 AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). The primary objective of this investigation was to see if these relationships could be…

This report explores the dynamic forces that heavy vehicles apply to road pavements and the effects that these forces have on pavement performance. The research focussed on identification of accurate and cost effective means to quantify dynamic…

This report is a scoping document aimed at establishing how road deterioration (RD) models can be developed on a probabilistic basis. Deterministic RD models provide an average estimate to a future condition which is not necessarily likely to be…

Austroads Project AT1064 Long Term Performance Monitoring to Develop Consistent Performance Models has been running since 1994-95. A review of the analysis of US long term pavement performance (US LTPP) data used to validate the performance…

This report improves the current approach to cost allocation, develops incremental pricing, and develops direct user charging. This report includes analysis of the relationship between road use and expenditure without considering road

This report documents the development of a preliminary set of load-wear-cost (LWC) relationships as a basis for estimating the short-run marginal road wear cost (SRMC) and long-run marginal road wear cost (LRMC) for the main road types comprising…
