This study assessed the effects of dexamphetamine with and without alcohol on simulated driving and cognitive tasks. 18 subjects participated in all 4 conditions: 10 mg dexamphetamine and 0.8g/kg alcohol, 10 mg dexamphetamine only, 0.8g/kg alcohol only, and a placebo control condition. A driving simulator was used to assess driving skills and risk taking on different road types. Cognitive perfo...

Driving simulators are used to conduct experiments on driver behavior, road design, and vehicle characteristics, etc. It is important that a driving simulator include a realistic simulation of surrounding vehicles in order to be a valid representation of real driving. This paper describes a model that generates and simulates surrounding traffic for a driving simulator. The model is built on est...

We propose an efficient and effective image generation system for an experimental mixed-reality traffice space. Our enhanced traffic/driving simulation system represents the view through a hybrid that combines virtual geometry with real images to realize high photo-reality with little human cost. Images for datasets are captured from the real world, and the view for the simulation system is cre...

Recent evidence suggests a relationship between cognitive impairment and glaucoma. Whether impaired visual perception in glaucoma contributes to reduced cognitive function in patients with dementia, or cognitive impairment further limits visual perception due to optic nerve damage in glaucoma is unclear. One objective of this study was to see if there were significant differences on measures of...

Development of advanced driver assistance systems and driving management systems requires careful and thorough evaluation of not only algorithms, but also user acceptance and adaptation. For that purpose, driving simulation provides an ideal environment by creating various driving situations that may not be possible in a test track for safety reasons and putting drivers in a simulation loop to ...
