This report summarises the findings of a three-year study which reviewed the safety performance of selected road infrastructure elements and provided solutions that were more closely aligned with the Safe System ideal.

This project has developed guidance on how signal management and operation should be undertaken to realise the intent of network operation planning and achieve the desired performance outcomes for road users.

Heavy vehicle crashes across Australia and New Zealand continue to be a major road safety issue. There are road design criteria that are not based on the requirements of heavy vehicles and the purpose of this study was to update criteria for…

This report documents a harmonised Austroads product acceptance process for ITS products in the road network. The process covers six steps including determination of performance requirements based on agreed key performance indicators (KPIs),…

This report documents the research undertaken for Austroads on bicycle lanes at roundabouts. An extensive literature review informed empirical data gathering.The literature review revealed strong evidence that bicycle lanes on the approach and…

Signalised interchanges and ramp metering are major components of the interface between the arterial road system and the motorway system. The control systems of motorways and arterials are often treated as separate control components, which can…

This study looked into four on-road public transport (ORPT) priority treatments including: full bus lane (FBL), set back bus lane (SBBL), queue jump bus lane (QJBL) and no priority (NP). Microsimulation traffic modelling (MSTM) is a useful tool for…

Accessibility is broadly defined as the variety of opportunities provided to people through efficient arrangement of land use and various modes of transport. It measures the ease with which people are able to find and reach the best suited…

This paper considers how several recent pedestrian-oriented bridges, all on Auckland’s Western Ring Route, provide new connections or re-establish severed connections between communities. As the architect involved in these bridges, I will also…

Priorities in bridge engineering are changing. The imperative has shifted subtly from minimum cost to “more for less”, requiring a more holistic approach to sustainable delivery which offers best value to the economy and society as a whole over the…
