Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and red ....Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and reduction strategies prevails. This research aims to develop a theoretical model that can be used to develop robust containment and reduction strategies to mitigate the adverse economic, productivity and safety consequences that materialize from performing rework during the construction of mega transport projects.Read moreRead less

This project aims to develop a novel asset management information model to improve the overall effectiveness of decision making in transport asset management. The project intends to provide logical formalisms and semantic features to value-adding asset information in key asset management areas. The expected outcome will be a new value-based asset management information model which provides semantically enriched asset information for decision-making concerning transport asset management. This will help reduce the cost, duration and effort required to acquire relevant asset information and improve the quality and data availability of current transport asset management systems.Read moreRead less
Motorway management system integrating safety, efficiency & sustainability. 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 flo ....Motorway management system integrating safety, efficiency & sustainability. 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
Innovative urban traffic congestion solutions: optimising road space using networks of multi-class priority lanes. This project strengthens national approaches to a pervasive Australian problem; growing traffic congestion deteriorating liveability, environmental health and economic performance of the cities. This project improves approaches for traffic priority design to improve the efficiency of several class of vehicles and therefore, reducing traffic congestion.
Development of a novel mobile sensory system for bridge health monitoring. The aim of this project is to provide accurate, rapid and cost-effective ‘health checks’ for bridges. Transportation infrastructures are subject to continuous degradation due to the environment, ageing and excess loading. This project plans to develop a vehicle equipped with sensors as a mobile sensing platform to catch the dynamic interaction between the vehicle and the bridge. The interaction information would be used t ....Development of a novel mobile sensory system for bridge health monitoring. The aim of this project is to provide accurate, rapid and cost-effective ‘health checks’ for bridges. Transportation infrastructures are subject to continuous degradation due to the environment, ageing and excess loading. This project plans to develop a vehicle equipped with sensors as a mobile sensing platform to catch the dynamic interaction between the vehicle and the bridge. The interaction information would be used to assess the health of the bridge infrastructure through substructuring techniques. The expected output of this project would enable managers to monitor the structural conditions and provide an economical infrastructure asset management scheme to protect the structure and human lives.Read moreRead less
Anisotropic behaviour of natural soft soils. This project aims to improve current engineering analysis methods, which often fail to predict the performance of infrastructure built on natural soft soils.

This project aims to improve current engineering analysis methods, which often fail to predict the performance of infrastructure built on natural soft soils. This project expects to develop a theoretical and mathematical framework to describe the response of soft soils to complex loading patterns imposed by transport and energy infrastructure. This will be informed by advanced laboratory experiments that transcend the capabilities of routine testing methods. The expected outcome of the project is a series of tools for the engineering analysis of earthworks and foundations built on soft soils that will underpin the construction of civil infrastructure on ground often too poor to be considered for other use.Read moreRead less

The project will provide a scientific basis for the quantified network evaluation of incentivisation strategies that will support enhanced transport planning thereby improving mobility across society.Read moreRead less
The effects of cyclic loading on partially saturated soils. This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numeric ....The effects of cyclic loading on partially saturated soils. This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numerical model that can predict the effects of cyclic loads, and provide updated engineering guidance to ensure the integrity of infrastructure dependent on partially-saturated soils. Improved predictions of the processes involved resulting from this project will have significant economic benefits, as well as ensuring the safety and security of infrastructure and reduced maintenance costs.Read moreRead less
