Probabilistic terrorism risk assessment and risk acceptability for infrastructure protection. The risk-based decision-making framework will enable security risks to be quantified and compared in a rational and consistent manner, for a range of terrorist threats to infrastructure and transport systems. This will allow risk mitigation to be maximised leading to optimal security expenditure.
Risk-Based Decision-Making for Terrorism and Infrastructure Security. The project intends to develop stochastic models to predict the likelihood and extent of damages, casualties and other losses from terrorist and military threats. Terrorism, security and defence policy-makers need robust probabilistic risk assessments to prioritise or optimise the protection of buildings and aviation infrastructure, as well as iconic structures and mass gatherings. A key focus of the project is malevolent and ....Risk-Based Decision-Making for Terrorism and Infrastructure Security. The project intends to develop stochastic models to predict the likelihood and extent of damages, casualties and other losses from terrorist and military threats. Terrorism, security and defence policy-makers need robust probabilistic risk assessments to prioritise or optimise the protection of buildings and aviation infrastructure, as well as iconic structures and mass gatherings. A key focus of the project is malevolent and accidental explosive blast loadings on civilian and hardened infrastructure. A quantitative assessment of security risks and risk acceptance criteria would allow the effectiveness of security measures to be assessed to provide cost-effective levels of protection that is acceptable to society.Read moreRead less

Summary
Optimisation of transit priority in a transportation network. This project is aimed at developing an optimised approach to combine various types of public transport priority in an urban network which can be used by transport planners to increase the efficiency of traffic movements and reduce traffic congestion. The case study is the network of Brisbane including all arterial and local roads.
A novel integrated motorway management system for less congested, more reliable and safer motorways. Motorway traffic congestion poses major economic, social and safety problems, which this project seeks to address through intelligent traffic management solutions as an alternative to massive infrastructure expansion. The project’s innovative traffic analysis and control system will reduce periods of congestion and increase driver safety.
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
Large-scale geotechnical analysis of new and aged pipeline infrastructure. This project aims to develop novel computational methods for predicting failure rates in geographically distributed pipeline networks affected by ground movements, one of the main triggers of bursts and leakages in buried pipe infrastructure.

This project aims to develop novel computational methods for predicting failure rates in geographically distributed pipeline networks affected by ground movements, one of the main triggers of bursts and leakages in buried pipe infrastructure. The project will be based on a blend of experimental work and development of simulation tools to quantify the coupled effects of pipe deterioration, poor backfilling and ground movements in aged and new pipelines. The results will feed towards the formulation of a framework for the large-scale stress analysis of segmented and continuous pipes, capable of using as input high-resolution geospatial observations and predictions of ground movements.Read moreRead less
Unsaturated soil-structure interaction with emphasis on buried pipelines. Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, ....Unsaturated soil-structure interaction with emphasis on buried pipelines. Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, using a new custom-built apparatus. Experimental results are expected to provide insight for developing a theoretical model to quantify the effect of soil moisture on pipe integrity, and propose design formulas. A general framework is intended to be developed for handling various unsaturated soil-structure interaction problems in geotechnical engineering.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

This project strengthens national approaches to a pervasive Australian problem, growing traffic congestion deteriorating liveability, environmental health & economic performance of the cities where most Australians live. Public transport can address these issues but most is provided by buses which are caught up in traffic congestion. This project improves approaches for traffic priority design to improve the effectiveness and efficiency of on-road public transport. It optimises the design of individual and groups of priority treatments and will generate diagnostic tools to better target priority treatments. Findings will better focus Australia's approach to increasingly challenging transport futures.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
