Driving exposure by driver age in Michigan
Background: This study compared driving exposure betweentwo high-crash-risk groups (16-17 and 18-24-yearolds), with a low-crash-risk group (35-64-year-olds). In addition, patterns of association between driving exposure measures and demographic and driving behavior variables were examined. Methods...
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...
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...
The impact of Michigan's text messaging restriction on motor vehicle crashes
The purpose of this study was to determine the effects of Michigan's universal text messaging restriction (effective July 2010) across different age groups of drivers and crash severities. Methods: Changes in monthly crash rates and crash trends per 10,000 licensed drivers aged 16, 17, 18, 19...
