Two full-frontal Crash Injury Research and Engineering Network (CIREN) motor vehicle crashes (MVCs) were reconstructed using finite element (FE) models. A FE simplified vehicle model (SVM) was tuned to mimic the frontal crash response of the CIREN case vehicle using frontal NCAP crash test data. The Total HUman Model for Safety (THUMS) was positioned in 120 pre-crash configurations per case wit...

INTRODUCTION Pregnancy causes diverse physiologic and lifestyle changes that may contribute to increased driving and driving error. We compared the risk of a serious motor vehicle crash during the second trimester to the baseline risk before pregnancy. METHODS We conducted a population-based self-matched longitudinal cohort analysis of women who gave birth in Ontario between April 1, 2006, an...

We did a retrospective case control study to examine the relationship between the risk of dying for Michigan motor vehicle crash (MVC) drivers and the type of county (rural/nonrural) of crash occurrence, while adjusting for crash characteristics, age, sex, and the medical resources in the county of crash occurrence. The 1987 Michigan Accident Census was used to obtain data regarding all MVC dri...

This paper examines NASS/CDS 1995 to 2001 in order to evaluate rollover crash severity metrics and to recommend additional data elements to assist in determining rollover severity. For belted occupants and unbelted ejected occupants in single vehicle crashes, the number of roof impacts is an appropriate severity indicator. For ejected occupants, the ejection risk generally increases with the nu...

PURPOSE The specific mechanisms by which peer passengers increase teen drivers' crash risk are not completely understood. We aimed to provide insight on the two primary hypothesized mechanisms, distraction and promotion of risk-taking behavior, for male and female teen drivers and further for select driver-passenger gender combinations. METHODS From the National Motor Vehicle Crash Causation ...

background while cyclists and pedestrians are known to be at significant risk for severe injuries when exposed to road traffic accidents (rta) involving trucks, little is known about rta injury risk for truck drivers. objectives the aim of this study was to analyze the injury severity in truck drivers following rtas. patients and methods our local accident research unit prospectively documented...

At a crash scene, EMS providers must not only determine the severity of injury and initiate medical management, but also identify the most appropriate transport destination facility through a process called “field triage.” Proper decision making has a very significant impact on the outcome of injured subjects. Step III of the Field Triage Decision Scheme addresses mechanisms of injury and previ...

BACKGROUND Practicing primary care physicians often encounter the difficult clinical situation of evaluating the older driver. We wanted to investigate the relation between self-reported driving behavior, neuropsychological measures, and crash risk to inform the development of a test battery that could predict unsafe driving behavior and was feasible for use by primary care physicians. METHOD...

Objective: To reexamine and refine estimates for alcohol-related relative risk of driver involvement in fatal crashes by age and sex as a function of B AC using recent data. Methods: Logistic regression was used to estimate age/sex specific relative risk of fatal crash involvement as a function of the BAC of fatally injured and surviving drivers by combining crash data from the Fatality Analysi...

BACKGROUND Insufficient sleep duration and obstructive sleep apnea, two common causes of sleep deficiency in adults, can result in excessive sleepiness, a well-recognized cause of motor vehicle crashes, although their contribution to crash risk in the general population remains uncertain. The objective of this study was to evaluate the relation of sleep apnea, sleep duration, and excessive slee...
