Optimisation of Road Network Maintenance Strategies for Life-Cycle Costs. The future of Tasmania and the nation as a competitive force in the international market is intimately linked to its transportation infrastructure network. The successful maintenance and performance of the road component is essential for an efficient and integrated system and minimisation of freight costs.

The future of Tasmania and the nation as a competitive force in the international market is intimately linked to its transportation infrastructure network. The successful maintenance and performance of the road component is essential for an efficient and integrated system and minimisation of freight costs. The research proposes to develop a less empirical and phenomenological method of predicting the future performance of pavements, based on optimisation of maintenance strategies, by incorporating the use of probabilistic methods and Geographical Information Systems (GIS) into new Whole of Life Costing (WOLC) models.Read moreRead less
Traffic Incidents: Reducing the Impacts. Road congestion due to traffic incidents in major urban areas adversely affects traveller safety and travel reliability, and is a significant cost burden to industry and the community in social, environmental and economic terms. This project will investigate the impact of traffic incidents, with the aim being to produce outcomes that contribute to more efficient traffic management, and specifically to reducing the incident duration. Outcomes will include ....Traffic Incidents: Reducing the Impacts.

This project will investigate the impact of traffic incidents, with the aim being to produce outcomes that contribute to more efficient traffic management, and specifically to reducing the incident duration. Outcomes will include the development of decision support tools to aid in policy and operational responses, as well as the development of faster and more comprehensive accident reconstruction based on spatial information technology.

Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer ....Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer and flushing is lost, with the result that the lake quickly becomes anoxic, resulting in fish kills. This project examines some aeration solutions to this problem.Read moreRead less
Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient co ....Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient concentrations, pose a significant threat to waterways yet a process-based description of phosphorus release is not yet possible. The outcome will be a verified model of phosphorus release mechanisms suitable for a range of water bodies.Read moreRead less

Internal wave energetics, mixing and transport in lakes. The aim of this project is to increase our understanding of the physical processes controlling water quality in lakes. Water supplies world-wide are under increasing pressure from development, usually resulting in decreasing water quality. The biology and chemistry in lakes is controlled primarily by physical processes, and so understanding these processes is crucial to managing water quality in lakes and reservoirs.

The aim of this project is to increase our understanding of the physical processes controlling water quality in lakes. Water supplies world-wide are under increasing pressure from development, usually resulting in decreasing water quality. The biology and chemistry in lakes is controlled primarily by physical processes, and so understanding these processes is crucial to managing water quality in lakes and reservoirs. The outcomes of this project will be improved tools for the management of these water resources, as all the research findings will be incorporated into already existing numerical models for lake management.Read moreRead less

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.

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
