Traffic microsimulation of ITS implementations in CBD road networks. This research project will investigate the advantages and disadvantages of using Intelligent Transport Systems (ITS) technologies in an Australian Central Business District (CBD) environment. It is often assumed that road networks and especially high activity areas such as CBDs can benefit significantly from ITS implementations. Traditionally ITS impacts have been difficult to quantify due to difficulties in isolating network ....Traffic microsimulation of ITS implementations in CBD road networks. This research project will investigate the advantages and disadvantages of using Intelligent Transport Systems (ITS) technologies in an Australian Central Business District (CBD) environment. It is often assumed that road networks and especially high activity areas such as CBDs can benefit significantly from ITS implementations. Traditionally ITS impacts have been difficult to quantify due to difficulties in isolating network effects and limitations with traditional traffic models. The project will overcome this difficulty by using a current state of the art traffic microsimulation model in order to test various ITS scenarios in a duplicate of a real world CBD.Read moreRead less
Wide Speed Range, Inverterless, Constant Current Mode Alternator. Increasing auxiliary electric power demands in cars due to proposed new features such as electromechanical valves and active suspension has created a pressing need for a higher power car alternator. There has also been a continuing need for improved alternators for small-scale renewable energy generation such as wind turbines. These applications require the lowest possible cost solution which meets the challenging technical spec ....Wide Speed Range, Inverterless, Constant Current Mode Alternator. Increasing auxiliary electric power demands in cars due to proposed new features such as electromechanical valves and active suspension has created a pressing need for a higher power car alternator. There has also been a continuing need for improved alternators for small-scale renewable energy generation such as wind turbines. These applications require the lowest possible cost solution which meets the challenging technical specifications. Present research in this area is focussed on expensive inverter-based methods. We propose a low-cost, "inverterless" alternator configuration based on a specially-designed interior permanent magnet machine operating in a new current source mode.Read moreRead less
Novel statistical analysis for traffic modelling. This collaborative research with Queensland Main Roads aims to develop and apply novel statistical modelling techniques which improve on the current statistical methods used for transport modelling. The research outcomes will provide a high level of accuracy in terms of predictions for trips leading to better use of expensive survey data. Predictions will be incorporated into transport models. Such model will be used for improving decisions i ....Novel statistical analysis for traffic modelling. This collaborative research with Queensland Main Roads aims to develop and apply novel statistical modelling techniques which improve on the current statistical methods used for transport modelling. The research outcomes will provide a high level of accuracy in terms of predictions for trips leading to better use of expensive survey data. Predictions will be incorporated into transport models. Such model will be used for improving decisions involving multi billion dollar transport infrastructure investment and applied to South East Queensland. The methods can be extended to transport models for other large conurbations in Australia. Outcomes include improved transport systems with economic benefits for business and the community.

Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the ....Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the engine requirements (via variable geometry intakes that can be under the control of the engine management computer) offering substantial reductions in fuel consumption and emissions.Read moreRead less
Methodology for assessing the vulnerability of multimodal transport networks and developing remedial measures to safeguard network performance. When transport networks fail, the effects on people and the economy can be devastating. The consequences for Hobart of the 1975 Tasman Bridge collapse provide a prime example. Failure may also result from extreme weather and natural disasters, traffic congestion and incidents, commercial failure, human error, or malevolence (such as sabotage). This proje ....Methodology for assessing the vulnerability of multimodal transport networks and developing remedial measures to safeguard network performance. When transport networks fail, the effects on people and the economy can be devastating. The consequences for Hobart of the 1975 Tasman Bridge collapse provide a prime example. Failure may also result from extreme weather and natural disasters, traffic congestion and incidents, commercial failure, human error, or malevolence (such as sabotage). This project will develop a methodology for auditing a transport network to identify where infrastructure failure will have the worst consequences for movement of people and goods. The research will provide tools for planners to determine critical network locations, and devise strategies and remedial measures to safeguard network performance.Read moreRead less
