This project aims to develop a motorway management system that holistically optimises motorway safety, efficiency, and sustainability via intervening the traffic flow dynamics. In the current practice of motorway traffic flow management, safety, efficiency, and sustainability are fundamentally connected but separately managed as they are modeled by distinct methodologies. The new system is based on a proposed traffic flow theory which includes a microscopic model for safety analysis and a derived macroscopic model for efficiency and sustainability analysis. This theory can be used to resolve the above-mentioned long unsettled challenge and significantly improve our motorway performance.Read moreRead less
Derivation of Emissions Models for Commercial Vehicles. This research project will develop emissions models for commercial vehicles that are capable of modelling changes in driver behaviour. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of opera ....Derivation of Emissions Models for Commercial Vehicles. This research project will develop emissions models for commercial vehicles that are capable of modelling changes in driver behaviour. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of operation. These models will then be able to describe the changes in emission characteristics under different commercial vehicle operating modes for a range of commercial vehicle types.Read moreRead less
Efficient geotechnical risk management of rock cliffs . Extreme events will significantly impact the severity of Australian rock cliff hazards in the coming years affecting infrastructure and public safety along major corridors and popular paths. Accurate prediction of their effect is crucial to analyse the associated rockfall risks and design mitigation measures.

Extreme events will significantly impact the severity of Australian rock cliff hazards in the coming years affecting infrastructure and public safety along major corridors and popular paths. Accurate prediction of their effect is crucial to analyse the associated rockfall risks and design mitigation measures. The project aims to provide a novel approach for the quantification of the rockfall risk by combining proximity remote sensing solutions, probabilistic models and quantitative risk analysis. The primary benefits lie in the ability to optimize protection reliability and costs and to deliver a rigorous method to support practitioners, government and emergency agencies to manage the risk, improve safety and properly allocate resources.Read moreRead less
Dynamic vulnerability of urban road networks. Road transport networks are vital to the economic and social health of our society. Poorly performing networks lead to significant costs and adverse environmental and health impacts. This project will develop methods and tools to predict the effects of network failure through incident-related congestion at bottlenecks (e.g. congestion from accidents, vehicle breakdowns, road works, lane blockages and road closures) and to suggest remedial action plan ....Dynamic vulnerability of urban road networks. Road transport networks are vital to the economic and social health of our society. Poorly performing networks lead to significant costs and adverse environmental and health impacts. This project will develop methods and tools to predict the effects of network failure through incident-related congestion at bottlenecks (e.g. congestion from accidents, vehicle breakdowns, road works, lane blockages and road closures) and to suggest remedial action plans in the case of bottleneck formation. Incident related congestion is responsible for more than 50% of the ($9.4B p.a.) cost of congestion in Australia's major cities.Read moreRead less
Vulnerability of Steel Lattice Towers to Fire. Steel lattice towers find widespread use as structural components in electricity transmission systems and as base towers in UHF and microwave communications networks. They tend be protected from bushfire damage by active backburning or clearing through their easement or right of way, because the response of towers to bushfires is surprisingly unknown, and it is not known if they can provide passive protection without clearing/backburning. A world fi ....Vulnerability of Steel Lattice Towers to Fire. Steel lattice towers find widespread use as structural components in electricity transmission systems and as base towers in UHF and microwave communications networks. They tend be protected from bushfire damage by active backburning or clearing through their easement or right of way, because the response of towers to bushfires is surprisingly unknown, and it is not known if they can provide passive protection without clearing/backburning. A world first, this Project aims to use advanced numerical techniques to assess the fragility and resilience of lattice towers in fire using a systems approach based on fire load data available with a further goal to explore potential pragmatic strengthening strategies if necessary and feasible.Read moreRead less

Time-dependent behaviour of precast concrete sandwich panels. This project seeks to improve understanding of the long-term structural behaviour of precast concrete sandwich panels and thus facilitate their use in civil engineering applications.

This project seeks to improve understanding of the long-term structural behaviour of precast concrete sandwich panels and thus facilitate their use in civil engineering applications. These panels offer many advantages over traditional concrete panels mainly due to their excellent thermal insulation and their use in civil and industrial engineering applications is expanding. Nevertheless, the literature reveals a lack of confidence in their design due to the absence of reliable numerical models and test data of their long-term structural behaviour. This project aims to provide insight into the nonlinear long-term behaviour of such panels by developing new theoretical models that will be validated by laboratory testing.Read moreRead less
