Using GPS data to understand driving behavior
This paper investigates driving behavior based on GPS data collected by the University of Michigan Transportation Research Institute (UMTRI). The database contains driving data for 78 drivers living in the Detroit metropolitan region in 2004, with automobile use tracked on a day-to-day basis for...
Is the U.S. on the path to the lowest motor vehicle fatalities in decades?
Trends in U.S. motor vehicle fatalities, gasoline sales, and distance driven were examined for 12 months from May 2007 through April 2008. The results show substantial year-to-year reductions in motor vehicle fatalities during this time period that cannot be fully explained by the reductions in...
Visual fatigue and the driver
The last fifty years of research on visual fatigue are surveyed, with special emphasis on results that may be important in the context of driving. Over that time, ideas about visual fatigue have varied, ranging from a broad application of the label eyestrain, to virtually any visual complaint (...
Mirror size and lane-change crashes.
This study examined the relationship between the size of the driver-side outside mirror and the frequency of lane-change crashes. To control for other vehicle and driver differences that might be associated with mirror size, the frequency of going-straight-ahead crashes was used for comparison. The...
Problem driving behavior and psychosocial maturation in young adulthood
This study examined the association between psychosocial maturation and problem driving behavior in young adulthood. Psychosocial maturation is the process of adopting adult roles, attitudes and behaviors and completing developmental tasks associated with becoming an adult. Past research has...
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...
