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?'

The initiation and control of action in motor vehicle driving. Every time we pull up to a traffic light or overtake another vehicle our brain is making a whole series of critical decisions about when and how to carry out the manoeuvre accurately and safely. This project seeks to better understand the processes involved. Using the latest, high fidelity GPS and accelerometer technology, highly accurate measurements of driver behaviour and vehicle dynamics will be made in a real vehicle.

Every time we pull up to a traffic light or overtake another vehicle our brain is making a whole series of critical decisions about when and how to carry out the manoeuvre accurately and safely. This project seeks to better understand the processes involved. Using the latest, high fidelity GPS and accelerometer technology, highly accurate measurements of driver behaviour and vehicle dynamics will be made in a real vehicle. Understanding when and how we carry out these types of basic tasks will play a central role in future brake, suspension and steering system design; will help guide the specifications of road and road sign design; and will help motivate additions or alterations to current driver training programmes.Read moreRead less
Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated t ....Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less

Using innovative occlusion and training research designs on a driving The proposed project examines the contribution of a mental model approach to the perception of time and speed of own and other vehicles using innovative occlusion and training research designs on a driving simulator. Participants will be asked to make time and speed estimations under varying environmetal conditions such as urban and rural scenes, straight and curved roads, and with and without engine noise, and under drug states. The generality of the findings will be tested on an instrumented car. The project will increase our understanding of factors influencing speed perception, a critical component of safe driving behaviour.Read moreRead less
Drivers' Behavioural Responses to Traffic Signs. Traffic signs are ubiquitous in the road environment; research to improve their effectiveness can be very cost-effective in terms of safety improvements. Conducting traffic sign research on real roads has many difficulties, such as ethical considerations and lack of control. To overcome this, the research will be conducted in a driving simulator, in which the interaction between drivers and their equipment/environment will be studied. The aim of ....Drivers' Behavioural Responses to Traffic Signs.

Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults.

Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to adaptation of roads, and vehicles to reduce crash risk among older Australians. This will reduce injury and healthcare costs and allow older Australians to maintain higher levels of social participation.Read moreRead less
Vision Impairment and Fitness to Drive. Vision is fundamental to driving. Intuitively vision impairments will significantly affect fitness to drive. However the relationship between vision and crash risk is not well understood and current tests are unreliable.

However the relationship between vision and crash risk is not well understood and current tests are unreliable. This study will describe the way in which specific vision conditions affect driving performance. The study will examine the effects of visual field loss on drivers' ability to monitor information, allocate attention and minimise the effect of distractions.

The Creation of an Eye Movement Recording Facility in Queensland. There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments).

As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.
This application proposes to purchase eye movement recording equipment to form a dedicated and truly collaborative facility to measure visual behaviour. The facility would be unique in Australia and would be invaluable to both further understand visual/cognitive processes and how individuals interact with their environments.Read moreRead less
