Optimisation of Rail Network Infrastructure Capacity under Dynamic Train Planning. Recent changes in railway operating environments have caused significant operational and management problems in Australia. This research will lead to improvements of railway's key managerial functions, namely: network capacity planning; rollingstock planning; train scheduling; and maintenance planning.

Recent changes in railway operating environments have caused significant operational and management problems in Australia. This research will lead to improvements of railway's key managerial functions, namely: network capacity planning; rollingstock planning; train scheduling; and maintenance planning. The major outcome of the research will be to develop an optimisation model to significantly improve the operating efficiency and assets productivity of Australia's rail system. The novelty of the research is that it will be undertaken using innovations based on modern job shop scheduling and sequencing optimisation techniques as the complexity of the problem makes it impossible to solve by classic optimisation techniques.Read moreRead less
Hybrid Job Shop Techniques for Dynamic Train Scheduling. The job shop approach to dynamic train scheduling promises considerable benefits over existing approaches, and allows problems of large size and complexity to be solved with great accuracy. The application of research results in Australia has the potential to:

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. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that wi ....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. 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
Stabilization of railway subgrade by lime-flyash slurry injection. The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key para ....Stabilization of railway subgrade by lime-flyash slurry injection. The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key parameters involved in the improvement of subgrade soil by injecting lime-flyash slurry. This project will develop an improved design procedure for lime-flyash slurry injection in the field based on experimental and numerical modelling.Read moreRead less
Multidimensional evaluation of the overall benefits of voluntary travel behaviour change programs. Voluntary Travel Behaviour Programs (VTBC) offer considerable promise for the management of traffic congestion and reduction in greenhouse gas and air quality emissions from road transport. Research to date has identified two outstanding issues: (1) measurement and evaluation of actual behaviour change and (2) identification of the full benefits and impacts of VTBC. Empirical studies indicate that ....Multidimensional evaluation of the overall benefits of voluntary travel behaviour change programs. Voluntary Travel Behaviour Programs (VTBC) offer considerable promise for the management of traffic congestion and reduction in greenhouse gas and air quality emissions from road transport. Research to date has identified two outstanding issues: (1) measurement and evaluation of actual behaviour change and (2) identification of the full benefits and impacts of VTBC. Empirical studies indicate that many of the benefits fall outside the transport area, including a wide range of socio-economic benefits to individuals and the community. This project will develop a survey tool for assessing benefits and impacts of VTBC within a properly designed and tested evaluation framework.Read moreRead less
The potential role of transit-oriented development in Australian cities: a critical assessment using a suburban rail corridor. Sustainability in urban development and a reduction in our dependence on the private car for mobility are key concerns in Australia and elsewhere. The results of this research will inform and lead world's best practice in the evaluation and adoption of sustainable transport solutions, especially those related to investment in urban public transport systems, and hence pro ....The potential role of transit-oriented development in Australian cities: a critical assessment using a suburban rail corridor. Sustainability in urban development and a reduction in our dependence on the private car for mobility are key concerns in Australia and elsewhere. The results of this research will inform and lead world's best practice in the evaluation and adoption of sustainable transport solutions, especially those related to investment in urban public transport systems, and hence provide options for planners and developers to minimise the impacts of developments on the environment. The benefits from the project will be in improved planning and design principles and planning tools for transit-oriented urban developments in both inner and outer suburbs in Australian cities.Read moreRead less
Valuation of service reliability and crowding under risk and uncertainty: neglected drivers of demand for public transport. The reliability of public transport services, and the amount of crowding at stations and also on trains and on buses, have come under strong criticism. This study identifies the role that improved service reliability and reduced crowding play in influencing the switch from car to public transport for the commute.
Optimising train driver vigilance system: reactivation of a fatigued driver. Fatigue poses frequent problems in train drivers. The repetitive nature of the train-driving task is a precursor of fatigue. This application proposes a novel design concept for the current train driver vigilance system manufactured by our industry partner. The proposed new vigilance system will not only assure that the driver is awake by warning of fatigue states, but will also act as an important cue in the control of ....Optimising train driver vigilance system: reactivation of a fatigued driver.

This application proposes a novel design concept for the current train driver vigilance system manufactured by our industry partner. The proposed new vigilance system will not only assure that the driver is awake by warning of fatigue states, but will also act as an important cue in the control of the train. Incorporating fatigue detection in the vigilance monitor is of commercial value to our industry partner. Furthermore, this study will help improve the safety culture of the railway environment.Read moreRead less
