Language processes during overt and covert speech in a simulated driving task
We used MEG to explore the neural correlates of language processing in a simulated driving environment. Functional MRI and MEG studies require subjects to remain still and not move their mouths, unlike real on-road driving conditions. MEG was used to identify the cortical regions engaged in...
Age-related differences in visual scanning at median-divided highway intersections in rural areas
The objective of this study was to examine age-related differences in visual scanning as drivers performed three separate maneuvers (going straight across, making a left and right turn) at two median-divided highway intersections with different crash frequencies. An on-road study was conducted with...
Legibility index for examining common viewing situations a new definition using solid angle.
The legibility levels of text and graphics can be assessed using the Legibility Index, conventionally defined as the distance at which material can be read with perfect accuracy (the legibility distance) divided by the character height. The ratio equals the inverse tangent of the visual angle...
Effects of time-gap settings of adaptive cruise control (ACC) on driving performance and subjective acceptance in a bus driving simulator
A study was conducted to investigate the effects of time-gap settings and contents of secondary tasks on a fix-based bus driving simulator on drivers- performance while reclaiming control from ACC in a car-following scenario of emergency brake by the lead vehicle. Thirty professional bus drivers...
Facilitating driver interaction with a robotic driving assistant Some insights from the literature.
Nissan has been exploring the idea of robots as driving aids, first demonstrating the PIVO robot at the 2005 Tokyo Motor Show and PIVO 2 at the 2007 Tokyo Motor Show. The robot consists of the top of an R2D2-like unit, with an expressive face, torso rotation, and speech output. It is positioned on...
In-vehicle video and motion sickness
This study consisted of a brief literature review of motion sickness and a paper-andpencil survey that focused on the frequency and severity of motion sickness of respondents- past experiences while viewing video in a moving vehicle. Also included in the survey were questions related to the...
Relationships among driver age, vehicle cost, and fatal nighttime crashes
The ratio of crashes in darkness to those occurring in daylight has been used to assess the relative sensitivity of certain risk factors to ambient light level. When applied in a way that maintains control over exposure level, use of dark/light ratios can be helpful in identifying crash factors...
