    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 ...
  • Assessing the Safety Impact of Roadway Improvements Using Naturalistic Driving Data--Feasibility Study 

    Li, Yingfeng; Medina, Alejandra; Gibbons, Ronald B. (National Surface Transportation Safety Center for Excellence, 2017-10-19)
