  • 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 (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, Zac; 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; Hanowski, Richard (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 (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 ...
  • Development of a Mobile Measurement System for Roadway Lighting 

    Gibbons, Ronald B.; Meyer, Jason; Edwards, Christopher J. (National Surface Transportation Safety Center for Excellence, 2018-01-04)
    In recent years, the complexity of the evaluation metrics of roadway lighting has continually increased. In order to measure the effectiveness of a roadway lighting system in situ, a mobile measurement system has been ...
  • Driver Coach Study: Using Real-time and Post Hoc Feedback to Improve Teen Driving Habits 

    Klauer, Charlie; Ankem, Gayatri; Guo, Feng; Baynes, Peter; Fang, Youjia; Atkins, Whitney; Baker, Stephanie; Duke, Rebekah; Hankey, Jonathan M.; Dingus, Thomas A. (National Surface Transportation Safety Center for Excellence, 2017-12-08)
    Novice teenage drivers have the highest rates of fatalities and injuries on U.S. roadways compared to any other age group. This experimental research was conducted to see if presenting novice teenage drivers and their ...
  • Development of Curriculum for the Virginia Driver's Licensing Ceremony 

    Duke, Rebekah; Klauer, Charlie; Baker, Stephanie (National Surface Transportation Safety Center for Excellence, 2017-12-06)
    In Virginia, to receive the actual driver’s license (as opposed to the temporary driving permit), both a parent and the teenage driver must appear before a family district court judge and participate in the Virginia Driver’s ...
  • Fact Sheets 

    Tidwell, Scott; Fitchett, Vikki; Blanco, Myra (National Surface Transportation Safety Center for Excellence, 2017-12-06)
    To extend its public outreach, the National Surface Transportation Safety Center for Excellence has created concise fact sheets describing research findings important to surface transportation safety. To date, fact sheets ...
  • Video Magnification to Detect Heart Rate for Drivers 

    Sarkar, Abhijit; Doerzaph, Zachary; Abbott, A. Lynn (National Surface Transportation Safety Center for Excellence, 2017-11-13)
    Heart rate is a strong indicator of a person’s psychophysiological state. For this reason, many applications would benefit from the ability to measure noncontact heart rate. The present work describes a new procedure for ...
  • Fatigue and Distraction in Occupational Light Vehicle Drivers 

    Soccolich, Susan A.; Hickman, Jeffrey S.; Hanowski, Richard J. (National Surface Transportation Safety Center for Excellence, 2017-10-25)
    Occupational drivers are a unique subset of the driving population, as driving per se is not their primary job duty, but can nonetheless encompass a large portion of their working day. These occupational drivers make sales ...
