Prior studies at Purdue University have shown that PTO entanglements occur most frequently on portable grain augers. A research project was conducted to measure operator exposure to PTO components and document work patterns during the use of grain augers. Information on the methodologies used to measure operator exposure is presented along with data on exposure to conventional grain augers whil...
Driving simulators can be used to evaluate driving performance under controlled, safe conditions. Teen drivers are at particular risk for motor vehicle crashes and simulated driving can provide important information on performance. We developed a new simulator protocol, the Simulated Driving Assessment (SDA), with the goal of providing a new tool for driver assessment and a common outcome measu...
OBJECTIVE To validate the recently published consensus criteria for screening commercial drivers for obstructive sleep apnea (OSA). METHODS A large, consecutive case series of commercial drivers was screened for OSA at a single occupational medicine clinic and those screening positive were referred for overnight polysomnography. RESULTS One hundred ninety (13%) of 1443 individuals having co...
This paper is the culmination of previous work to determine if steering behavior could be used to unobtrusively detect driver fatigue. The driving performance of 17 sleep-deprived heavy-truck drivers was monitored on a closed track. Functions in the time, frequency, and phase domains were developed to quantify changes in steering wheel input. The steering-based weighting functions which correla...
OBJECTIVE The objective of this study was to assess relationships between body mass index (BMI) and comorbid conditions within a large sample of truck drivers. METHODS Commercial driver medical examination data from 88,246 commercial drivers between 2005 and 2012 were analyzed for associations between BMI, medical disorders, and driver certification. RESULTS Most drivers were obese (53.3%, ...
Evaluating the horizontal curve indices performance of freeways is important to developing an understanding of impact to driver safety and comfort. Based on the well-established theory and measurement of driving workload, typical vehicles (include passenger car and truck) were chosen for field driving test with randomly samples of 28 driver. In this research we analyzed the 652 horizontal curve...
Objective: The objective of this study was to assess relationships between body mass index (BMI) and comorbid conditions within a large sample of truck drivers. Methods: Commercial driver medical examination data from 88,246 commercial drivers between 2005 and 2012 were analyzed for associations between BMI, medical disorders, and driver certification. Results: Most drivers were obese (53.3%, B...
BACKGROUND Blood pressure (BP) is a complex, multifactorial clinical outcome driven by genetic susceptibility, behavioral choices, and environmental factors. Many molecular mechanisms have been proposed for the pathophysiology of high BP even as its prevalence continues to grow worldwide, increasing morbidity and marking it as a major public health concern. To address this, we evaluated miRNA p...
