Fatigue contributes to 20% of fatal car crashes. Profile line-marking (PLM) aims to reduce fatigue-related crashes by alerting drivers when they begin veering off the road. Substantial stretches are laid annually Australia-wide, although evaluations of PLM have been unsophisticated or flawed. We aim to improve understanding of PLM impacts by investigating: 1)beliefs/attitudes regarding PLM (e.g. "PLM damages cars"); 2)whether road-edge PLM increases head-on crashes; 3)the efficacy of PLM with more widely spaced "ribs", with and without separate raised pavement markers; 4)underlying mechanisms (e.g. reducing fatigue, increasing visibility during night/wet) in order to improve the efficacy and efficiency of PLM use.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?'

The proposed research offers three significant benefits. First, this research will develop an improved approach to aid the design and testing of road safety anti-speeding messages. Second, the research will identify the most effective advertising messages for different groups of drivers at risk of being involved in road-related trauma such as young males. Third, through improving the persuasiveness of anti-speeding advertising messages, the research may contribute to a reduction in the extent to which drivers engage in speeding which, in turn, may lessen speeding-related road trauma which would have significant benefits not only for road safety but for public health more broadly.

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
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. 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 ....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. 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. Outcomes of the study will enable the development of evidence-based guidelines for assessment of vision for driving and effective countermeasures to enhance mobility and reduce crash risk.Read moreRead less
Developing vehicle-based advanced warning countermeasures for driver fatigue. Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status.

Driver fatigue is a major problem in Australia in terms of health, road safety and economic impact. Countermeasures to combat the influence of driver fatigue have been limited to public campaign strategies like resting every 2 hours. There has been little robust research on developing on-road countermeasures that could warn the driver of their fatigue status. This proposed project involves a collaboration with Compumedics Ltd, a leading medical device company, to conduct sophisticated research into developing an EEG and wheel behaviour fatigue countermeausure. We will further explore EEG and wheel behaviour patterns associated with fatigue, investigate noise control strategies, and conduct laboratory and on road field trials of the fatigue monitor. If this device is able to assess fatigue reliably and warn drivers in sufficient time to avert accidents, then substantial economic and social benefits will occur.Read moreRead less

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
