Effect of in-vehicle touch screen position on driver performance
The effect of touch-screen monitor placement on in-vehicle task performance and driving performance was examined in a driving simulator. Sixteen subjects drove behind a lead vehicle while interacting with a menu-based interface that required looking, planning, reaching, and touching. The vehicle...
Sitter-selected postures in an office chair with minimal task constraints
Studies of office workers- postures indicate that reclined postures are less common than upright or forward-leaning postures. Laboratory studies have shown that back extensor activity and internal pressure in the lumbar intervertebral disks are lower in reclined postures. Given these advantages,...
Intersection kinematics a pilot study of driver turning behavior with application to pedestrian obscuration by A-pillars
Vehicle turn trajectories from a naturalistic driving database were modeled using Bezier curves. A-pillar geometry from 56 vehicles was analyzed to develop representative and extreme cases of A-pillar obscuration. A new methodology was developed for quantifying plan-view obscuration in...
Assessing child belt fit
A total of 49 dynamic sled tests were performed with the Hybrid III 10YO to examine issues relating to child belt fit. The goals of these tests were to evaluate ATD response to realistic belt geometries and belt fit, develop methods for accurate, repeatable evaluation of restraint conditions for...
Fetal outcome in motor-vehicle crashes effects of crash characteristics and maternal restraint.
This project was undertaken to improve understanding of factors associated with adverse fetal outcomes of pregnant occupants involved in motor-vehicle crashes. In-depth investigations of crashes involving 57 pregnant occupants were performed. Maternal and fetal injuries, restraint information,...
Abdominal injury in motor-vehicle crashes
A review of the biomechanical and epidemiological literature on abdomen injury in motor-vehicle crashes was performed. Results of this review demonstrate that (1) there are limited data on abdomen injuries in real-world crashes of newer model airbag-equipped vehicles, (2) there are insufficient...
A numerical investigation of factors affecting cervical spine injuries during rollover crashes
Study Design. Factors affecting the risk of cervical spine injury in rollover crashes were investigated using a detailed finite element human head-neck model. Objective. Analyze systematically neck responses and associated injury predictors under complex loading conditions similar to real-world...
