    Grove, Kevin; Soccolich, Susan A.; Hanowski, Richard J. (National Surface Transportation Safety Center for Excellence, 2019-03-25)
    This study compared whether commercial motor vehicle drivers spent less time looking at the roadway while cruise control was engaged. The trucks in the study were equipped with commercially available systems that provide ...
  • Commercial Motor Vehicle Operator Fatigue Detection Technology Catalog and Review 

    Mabry, J. Erin; Glenn, T. Laurel; Hickman, Jeffrey Scott (National Surface Transportation Safety Center for Excellence, 2019-02-21)
    According to the National Academies of Science, Engineering, and Medicine, fatigue plays a role in up to 20% of fatal commercial motor vehicle (CMV) crashes. Because fatigue is difficult to self-assess, the use of fatigue ...
  • Identification of Cognitive Load in Naturalistic Driving 

    Angell, Linda; Perez, Miguel A.; Soccolich, Susan A. (National Surface Transportation Safety Center for Excellence, 2015-07-28)
    Over the last decade, naturalistic driving studies have provided significant insight into issues pertaining to the roles of distraction, inattention, and drowsiness in crash risk. New techniques have been developed for ...
  • A Preliminary Investigation into the Safety-Critical Event Risk of Aging Commercial Motor Vehicle Drivers 

    Dunn, Naomi; Antin, Jon; Soccolich, Susan A. (National Surface Transportation Safety Center for Excellence, 2018-09-07)
    The majority of research into age-related declines in driving performance has concentrated on light vehicle, non-commercial drivers. However, the aging of the commercial motor vehicle (CMV) workforce raises a number of ...
  • Strategies for Combating Drowsy Driving Using Adaptive Workload and Secondary Task Countermeasures 

    Llaneras, Robert; Meyer, Jason; Short, Maureen; Rayes, Freddy (National Surface Transportation Safety Center for Excellence, 2018-07-25)
    This study evaluated the effectiveness of alternative workload-based interventions intended to restore driver alertness following drowsy episodes. The study served as a proof of concept for varying the nature and onset of ...
  • Application of Proximity Sensors to In-vehicle Data Acquisition Systems 

    Krothapalli, Ujwal; Stowe, Loren; Doerzaph, Zachary; Petersen, Andy (National Surface Transportation Safety Center for Excellence, 2018-05-02)
    Naturalistic driving studies rely on human data reductionists to manually review and annotate driving behaviors. This work is time-consuming, and algorithms that could scan and categorize video data could make the data ...
  • Applying the Crash Trifecta Approach to SHRP 2 Data 

    Dunn, Naomi; Hickman, Jeffrey; Soccolich, Susan A.; Hanowski, Richard J. (National Surface Transportation Safety Center for Excellence, 2018-04-06)
    The crash trifecta model does not consider crash genesis as a simple unitary element, but rather as a convergence of three separate, converging elements: (1) unsafe pre-incident behavior or maneuver; (2) transient driver ...
  • Problematic Roadway Environments for Automated Vehicles 

    Terry, Travis N.; Tanner, Stephen (National Surface Transportation Safety Center for Excellence, 2018-04-03)
    Progress in the area of automated vehicles (AVs) will benefit safety, mobility, and environmental sustainability. Of the roughly 30,000 traffic-related fatalities reported yearly, 94% are due to human error. AVs replace ...
  • Moth Effect: Determining Contributing Factors 

    Terry, Travis N. (National Surface Transportation Safety Center for Excellence, 2018-01-31)
    The “moth effect” theory posits that drivers are attracted to or mesmerized by light much as moths are drawn to a flame. The notion that drivers are susceptible to the moth effect is born from the fact that vehicles stopped ...
