Integrating Attribute Decision Heuristics into Travel Choice Models that accommodate Risk Attitude and Perceptual Conditioning. This proposal has the specific objective of integrating two disconnected literatures that are having a major influence on the behavioural and statistical performance of discrete choice models in travel choice modelling. These fields are attribute processing strategies and the conditioning of the marginal utility of attributes by risk attitude and perceptual conditioning ....Integrating Attribute Decision Heuristics into Travel Choice Models that accommodate Risk Attitude and Perceptual Conditioning. This proposal has the specific objective of integrating two disconnected literatures that are having a major influence on the behavioural and statistical performance of discrete choice models in travel choice modelling. These fields are attribute processing strategies and the conditioning of the marginal utility of attributes by risk attitude and perceptual conditioning. These two major developments have not been jointly integrated into a behaviourally richer representation of choice making. Given the encouraging evidence from both literatures, the research will determine more precisely the benefits in terms of improved estimates of willingness to pay for specific attributes and also increased predictive power.

Shape adaptive structures with built-in compact smart material based actuators. Primary Australian aerospace manufacturers are sub-contractors and constantly compete in the global market. Their products are primarily control surfaces, e.g., Boeing 757 and 777 rudders, 737 Krueger flaps.

Ferroelectric single crystals were invented 5 years ago, and they possess many superior properties compared to conventional piezoelectric materials, particularly the induced strain up to 1.5%, an order higher than conventional materials. This project aims to poineer the application of these new and powerful smart materials as actuators and sensors to shape control of smart structures. The expected outcomes are (a) a new constitutive theory for the non-linear behaviour of ferroelectric single crystals; (b) a novel definition and formulation for the shape control problem; and (c) an innovative theoretical framework for design optimization of shape control of smart structures using ferroelectric single crystals.Read moreRead less

Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation.

Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that will have significant impact on the design and maintenance of future rail and road networks. A full understanding of the breakage mechanisms of aggregates will lead to innovative techniques in design and construction, including faster trains carrying heavier loads with reduced maintenance costs.Read moreRead less
Travel time budget analysis from multi-day and multi-year data. This research will investigate whether people have stable budgets for daily travel time and travel cost expenditure. Stable budgets have enormous implications for how various transport policies and investments are likely to affect the way people choose to travel and will likely change various policy and investment decisions related to transport.
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.

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

Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will design and perform first-of-kind experiments that reproduce the complex fluid-thermal-structural interactions representative of those experienced by these aircraft and rockets. We will then use these measurements to assess, validate and improve the current state-of-the-art of simulation and modelling approaches for design.Read moreRead less
