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.

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

The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.Read moreRead less

Floating structures are facing severe deterioration problem due to steel corrosion. This project proposes to address the deterioration problem by developing prefabricated high-performance fibre-reinforced polymer (FRP)-ultra-high performance cementitious (UHPC) composite elements for future floating structures. FRP-UHPC composite elements have excellent strength-to-weight ratio and improved durability. Basic mechanical properties and durability of FRP-UHPC composites will be investigated. Also, reliable connection device for FRP-UHPC structural units will be proposed and verified. The project is expected to provide durable floating structures with low maintenance cost, leading to a revolution of the current floating structures.Read moreRead less
Lightly Loaded Energy Farm Foundations in Cracked Desiccated Soil. This project aims are to understand the effects of seasonal changes in moisture on piles in clayey soils that develop desiccation cracks during dry times of the year. The project is significant because the economics of energy farms requires low cost foundations for their viability, but current methods of foundation design require long piles to overcome uncertainties in capacity and serviceability when soil shrinks in dry periods ....Lightly Loaded Energy Farm Foundations in Cracked Desiccated Soil. This project aims are to understand the effects of seasonal changes in moisture on piles in clayey soils that develop desiccation cracks during dry times of the year. The project is significant because the economics of energy farms requires low cost foundations for their viability, but current methods of foundation design require long piles to overcome uncertainties in capacity and serviceability when soil shrinks in dry periods and swells in wetter periods. The main outcome of the project will be recommendations for the design of lightly loaded pile foundations in soils that shrink and swell significantly. The benefits will be the reduced risk and cost associated with the geotechnical aspects of foundation design.Read moreRead less
Behavioural responses to transport congestion: peak spreading and the more efficient usage of transport infrastructure. Transport networks in cities such as Sydney are at or near capacity. It is no longer socially, environmentally or financially sustainable to continue supplying additional transport infrastructure to meet increased demand. An alternative is to make better use of existing infrastructure by spreading demand more evenly across the day. This project will test behavioural responses t ....Behavioural responses to transport congestion: peak spreading and the more efficient usage of transport infrastructure. Transport networks in cities such as Sydney are at or near capacity. It is no longer socially, environmentally or financially sustainable to continue supplying additional transport infrastructure to meet increased demand. An alternative is to make better use of existing infrastructure by spreading demand more evenly across the day. This project will test behavioural responses to increased congestion and quantify the phenomenon of peak spreading. It will assess economic costs and benefits of using congestion as a signal to encourage more efficient network usage, and examine other tools (e.g. time-based transport pricing) to encourage more efficient use of transport infrastructure.Read moreRead less
Dynamic vulnerability of urban road networks. Road transport networks are vital to the economic and social health of our society. Poorly performing networks lead to significant costs and adverse environmental and health impacts. This project will develop methods and tools to predict the effects of network failure through incident-related congestion at bottlenecks (e.g. congestion from accidents, vehicle breakdowns, road works, lane blockages and road closures) and to suggest remedial action plan ....Dynamic vulnerability of urban road networks. Road transport networks are vital to the economic and social health of our society. Poorly performing networks lead to significant costs and adverse environmental and health impacts. This project will develop methods and tools to predict the effects of network failure through incident-related congestion at bottlenecks (e.g. congestion from accidents, vehicle breakdowns, road works, lane blockages and road closures) and to suggest remedial action plans in the case of bottleneck formation. Incident related congestion is responsible for more than 50% of the ($9.4B p.a.) cost of congestion in Australia's major cities.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
