Integrating Accident and Travel Delay Externalities in an Urban Speed Reduction Context. The recognition that accident externalities are not independent of travel delays, and hence travel time savings and losses will promote a serious policy rethink about strategies designed to reduce the risk of exposure to accidents. The evidence is designed to identify that additional externality that has to be factored into the accident costs to recognise the other sources of externality typically ignored in ....Integrating Accident and Travel Delay Externalities in an Urban Speed Reduction Context. The recognition that accident externalities are not independent of travel delays, and hence travel time savings and losses will promote a serious policy rethink about strategies designed to reduce the risk of exposure to accidents. The evidence is designed to identify that additional externality that has to be factored into the accident costs to recognise the other sources of externality typically ignored in accident costing and speed restriction studies. The implication on the development of a national program of road safety is likely to be profound. Read moreRead less
Freight Transport and the Environment. Freight transport is a major contributor to traffic congestion and environmental blight in urban areas and adds sizeable costs to final consumption and the terms of trade, yet we currently lack any policy-rich predictive demand models. This program fills this gap. Using ideas from supply chain alliance, stated choice methods and behavioural models we develop a research program to understand and predict the environmental and traffic impacts of the freight di ....Freight Transport and the Environment. Freight transport is a major contributor to traffic congestion and environmental blight in urban areas and adds sizeable costs to final consumption and the terms of trade, yet we currently lack any policy-rich predictive demand models. This program fills this gap. Using ideas from supply chain alliance, stated choice methods and behavioural models we develop a research program to understand and predict the environmental and traffic impacts of the freight distribution task for key commodity classes in respect of origin, destination, trip timing, routing, selection of vehicle type and the way that consolidation is undertaken in freight distribution.Read moreRead less
Modelling the Dynamics of Urban Passenger Travel Activity of Seniors in an Ageing Population. Seniors in an ageing population (SAPS) are a significant and growing segment of the population. As (relatively) cash rich and time poor, they have very high expectations in respect of levels of accessibility and mobility required from the transport system, as well as from other supporting networks. We currently lack policy-rich travel demand models to assist in understanding the complex dynamics that ....Modelling the Dynamics of Urban Passenger Travel Activity of Seniors in an Ageing Population. Seniors in an ageing population (SAPS) are a significant and growing segment of the population. As (relatively) cash rich and time poor, they have very high expectations in respect of levels of accessibility and mobility required from the transport system, as well as from other supporting networks. We currently lack policy-rich travel demand models to assist in understanding the complex dynamics that influence the travel activities of SAPS. Using ideas from stated choice methods, interactive agency choice experiments, panel econometrics and behavioural discrete choice models we propose a research program designed to understand these demands. Special focus is given to support networks and the ways in which these impact on the demand for car and public transport use, as well as meeting the access needs to health-support and leisure facilities and to supporting networks of family and friends.Read moreRead less
IMPACTS OF TRANSIT LED DEVELOPMENT IN A NEW RAIL CORRIDOR. Impacts of transit-oriented development (TOD) in precincts adjoining the new Perth-Mandurah railway will be addressed by longitudinal survey. Results of a revealed preference questionnaire about actual trips will be combined with a stated choice questionnaire. Aims are to quantify the effects of TOD on rail and car use and on daily activities, new railway services on the travel behaviour of households near new station precincts, differin ....IMPACTS OF TRANSIT LED DEVELOPMENT IN A NEW RAIL CORRIDOR. Impacts of transit-oriented development (TOD) in precincts adjoining the new Perth-Mandurah railway will be addressed by longitudinal survey. Results of a revealed preference questionnaire about actual trips will be combined with a stated choice questionnaire. Aims are to quantify the effects of TOD on rail and car use and on daily activities, new railway services on the travel behaviour of households near new station precincts, differing accessibility of station precincts on household travel patterns, improved accessibility on economic activity and employment. Replacement of car-trips by walking and cycling, changes in shopping & leisure activities & the effect of trip-chaining on number of trips are of particular interest.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
Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast. Accurate judgement of the speed of 3D motion is essential to many real world tasks, from driving a vehicle to playing sports. Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding ....Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast. Accurate judgement of the speed of 3D motion is essential to many real world tasks, from driving a vehicle to playing sports. Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding of these effects will inform road safety policy and practice to benefit drivers and pedestrians and to guide the manufacturing of eyewear and display devices (eg. military heads-up-displays). It is also anticipated that this project will be able to answer the much-debated question 'What colour should cricket balls be?'

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.

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
