This study examines the pattern of facial fractures in automotive collisions using the National Automotive Sampling System - Crashworthiness Data System. The database was examined for trends within collision and occupant descriptors among occupants sustaining facial fractures. Drivers and right front passengers were included in an analysis of frontal collisions. Side impacts were assessed separ...

Children, small female, elderly, and obese occupants are at greater risk of death and serious injuries in motor-vehicle crashes than the mid-size, young, male occupants. However, current injury assessment tools, including crash test dummies and finite element (FE) human models, generally do not account for different body shape and composition variations among the population. The opportunity to ...

The 2000 United States Census counted 35 million residents aged 65 years old or older. Projections indicate that this number will increase to 63 million by 2025. This increase is important for those concerned about vehicle safety because older drivers and passengers are vulnerable road users. Much of the previous research concentrates on the role of the aging process on crash involvement among ...

In this study, we used analytic morphomics to understand the mechanisms of rib fracture for older occupants in frontal crashes. Analytic morphomics extracts body features from computed tomography scans of people involved in vehicle crashes who have been treated at the University of Michigan, a Level‐1 trauma center. Chest injury and rib fracture patterns w...

Thoracic organ injuries account for 13% of all serious injuries to belted front seat occupants in frontal crashes. The rate at which thoracic organ injury occurs and the manner in which the injuries occur has not changed significantly with the inclusion of airbags. This study was based on the injury outcomes of over 28,000 belted occupants in frontal crashes from National Automotive Sampling Sy...

The objective of this study is to investigate the effects of obesity on occupant responses in frontal crashes using whole-body human finite element (FE) models representing occupants with different obesity levels. In this study, the geometry of THUMS 4 midsize male model was varied using mesh morphing techniques with target geometries defined by statistical models of external body contour and e...

Click It or Ticket is a national campaign coordinated annually by the National Highway Traffic Safety Administration to increase the proper use of seat belts. In 2014, more than 21,000 passenger vehicle occupants died in motor vehicle crashes in the United States; 49% were unrestrained at the time of the crash (1). An additional 2.4 million occupants (restrained and unrestrained) were treated i...

This study sought to determine whether fitting a more aggressive seat belt reminder system to new vehicles would be cost-beneficial for Australia. While seat belt wearing rates have been observed around 95% in the front seat, non-wearing rates in casualty crashes are as high as 33% among persons killed and 19% among seriously injured occupants. Benefits were computed for three device options (s...

Background and purpose: Elevated CO2 rate in a building affect the health of occupant. This document presents results of an experimental analysis conducted in 50 offices located in 12 buildings with different layer in Cameroon (Yaounde). This study took place in 2012, during the dry and the rainy seasons. The main goal is to show the influence of the building structure, the ventilation and the ...
