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
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?'
