Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such ve ....Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such vehicles in regional centres by producing: (1) an assessment methodology to deal with options for network efficiency gains which will capture the full impacts; and (2) a computer modelling tool based on fundamental research to quantify those impacts, in terms of delays and accident rates.Read moreRead less

The aims of the network are to integrate the activities of researchers and practitioners in the areas of vehicles and road infrastructure and through cross-disciplinary collaboration apply intelligent control systems to deliver mobility, which is safer for all users, reduces driver stress and environmental impact with increased local manufactured content and improved cost effectiveness. It is of great significance to provide a cohesive solution to the transport problem considering all modes, environmental impacts, and economical and social considerations. This project should lead to a report identifying Australia's capability in this sector and a roadmap for a future research network integrating university and industry based research.Read moreRead less
A Human Factors Approach to the Design of Visual Information in the Highway Environment. Visual information in the highway environment affects drivers' perception, behaviour, and accident propensity. Using a range of methods and approaches, issues of key importance in road design will be addressed, e.g. (1) how increasing visual clutter in the road environment affects accident-producing behaviour, (2) how certain road situations create particular problems for the increasing number of older drive ....A Human Factors Approach to the Design of Visual Information in the Highway Environment. Visual information in the highway environment affects drivers' perception, behaviour, and accident propensity. Using a range of methods and approaches, issues of key importance in road design will be addressed, e.g. (1) how increasing visual clutter in the road environment affects accident-producing behaviour, (2) how certain road situations create particular problems for the increasing number of older drivers, and (3) how the road environment can be redesigned to reduce fundamental perceptual errors made by drivers. The proposal will generate new guidelines for how future road design can be optimised to minimise crash rates.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. 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 ....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. 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
iMATCH: Independent mobility, active travel and children's health. Policy interventions are used across Australia to improve children's independent mobility, to increase children's physical activity levels and social interaction, and to generate more sustainable travel behaviour, particularly for the journey to school. iMATCH provides a holistic and inter-disciplinary evaluation of policy interventions than is undertaken for most evaluations of school travel and children's travel behaviour polic ....iMATCH: Independent mobility, active travel and children's health. Policy interventions are used across Australia to improve children's independent mobility, to increase children's physical activity levels and social interaction, and to generate more sustainable travel behaviour, particularly for the journey to school. iMATCH provides a holistic and inter-disciplinary evaluation of policy interventions than is undertaken for most evaluations of school travel and children's travel behaviour policies and programs. By controlling for the influence of the built and social environment, the project will provide the necessary support to justify these policy interventions and to identify key improvements for their delivery, supporting more sustainable and healthy lifestyles for Australia's children.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
Heavy vehicle peaks in the pattern of night-time road traffic noise: Human health and management of urban freight movement. The Australian road freight industry is a significant economic activity and is growing at an unprecedented rate. Also growing is community reaction to the health effects of truck noise, to the extent that it is recognised as a major constraint to future transport operations, particularly night-time movements in metropolitan areas and in rural towns. This research will benef ....Heavy vehicle peaks in the pattern of night-time road traffic noise: Human health and management of urban freight movement. The Australian road freight industry is a significant economic activity and is growing at an unprecedented rate. Also growing is community reaction to the health effects of truck noise, to the extent that it is recognised as a major constraint to future transport operations, particularly night-time movements in metropolitan areas and in rural towns. This research will benefit the community as well as transportation and environmental authorities at all levels of government that are grappling with the challenge of managing constraints to the growth of this important industry but at the same time protecting human health and well-being.Read moreRead less
Advancement of Vacuum Pressure Application via Prefabricated Vertical Drains for Stabilising Soft Ground. Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings.

Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of vacuum preloading, together with vertical drains for soft soil stabilisation, can reduce construction and maintenance costs, while the increased soil strength will enhance the stability of infrastructure. This project will deliver design guidelines and specifications of enhanced vacuum consolidation application, as well as improving industrial competitiveness and export earnings through increased technology transfer.Read moreRead less
Effectiveness of prefabricated vertical band drains (PVD) in the stabilisation os soft clays. Stabilisation of structures in low-lying coastal Australia is affected by excessive settlement, low bearing capacity, and high lateral displacement of soft clays upon loading. The use of prefabricated vertical drains (PVD) prior to main construction can ensure pre-compression of soft clays by rapid pore water pressure dissipation, thereby increasing the soil strength and minimising its post construction ....Effectiveness of prefabricated vertical band drains (PVD) in the stabilisation os soft clays. Stabilisation of structures in low-lying coastal Australia is affected by excessive settlement, low bearing capacity, and high lateral displacement of soft clays upon loading. The use of prefabricated vertical drains (PVD) prior to main construction can ensure pre-compression of soft clays by rapid pore water pressure dissipation, thereby increasing the soil strength and minimising its post construction deformation. The main goal is to fully understand the stabilising mechanisms of PVD in soft clay, and to minimise the unfavourable effects of soil disturbances (smear) during installation. Extensive laboratory and field studies plus computer modelling will result in innovative design concepts and enhanced construction practices.Read moreRead less
Freight Transport and the Environment.
