    • Tips for Sharing the Road with Commercial Motor Vehicles: A Web-Based Approach 

      Dunn, Naomi J.; Baker, Stephanie Ann; Blanco, Myra (National Surface Transportation Safety Center for Excellence, 2016-01-11)
      This report documents the Tips for Sharing the Road with Commercial Motor Vehicles website (http://www.cmvroadsharing.org). The website was created by the National Surface Transportation Safety Center for Excellence to ...
    • Towards developing a US-EU common distracted driving taxonomy : updating a naturalistic driving data coding approach 

      Hanowski, Richard J. (Virginia Tech. Virginia Tech Transportation Institute, 2011-12-07)
      Naturalistic video data reduction is a process of identifying information from video and putting it into a format that can be analyzed. Developing a sufficiently detailed event coding scheme is critical to this process. ...
    • Transportation Research Today: The NSTSCE Quarterly Newsletter 

      Tidwell, Scott; Fitchett, Vikki L.; Blanco, Myra (National Surface Transportation Safety Center for Excellence, 2015-11-02)
      The National Surface Transportation Safety Center for Excellence (NSTSCE) newsletter, Transportation Research Today, was published quarterly from January 2014 to October 2014. The newsletter described NSTSCE research and ...
    • Undiagnosed Obstructive Sleep Apnea in Commercial Motor Vehicle Drivers: Application of STOP-Bang 

      Glenn, T. Laurel; Mabry, Jessica E.; Soccolich, Susan A.; Hickman, Jeff S. (National Surface Transportation Safety Center for Excellence, 2020-04-06)
      Although several studies have estimated the prevalence of obstructive sleep apnea (OSA) in the commercial motor vehicle (CMV) driver population, limitations such as small sample sizes and study samples that are not ...
    • Using Functional Classification to Enhance Naturalistic Driving Data Crash/Near Crash Algorithms 

      Sudweeks, Jeremy D. (2015-01-20)
      A persistent challenge in using naturalistic driving data is identifying events of interest from a large data set in a cost-effective manner. A common approach to this problem is to develop kinematic thresholds against ...
    • Vehicle Information Reporting Systems 

      Fitzgerald, Kaitlyn; Blanco, Myra (National Surface Transportation Safety Center for Excellence, 2020-09-22)
      The Vehicle Identification Number (VIN) standard currently tracks data elements such as manufacturing details, vehicle descriptors, vehicle security codes, and serial numbers. To date, the VIN standard does not include ...
    • Video Magnification to Detect Heart Rate for Drivers 

      Sarkar, Abhijit; Doerzaph, Zachary R.; 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 ...
    • Virtual Reality as a Tool to Evaluate Pedestrian Safety 

      Bhagavathula, Rajaram; Williams, Brian; Owens, Justin; Gibbons, Ronald B. (National Surface Transportation Safety Center for Excellence, 2020-06-25)
      Virtual reality (VR) promises to be an effective tool to evaluate changes to the built environment that could improve safety for pedestrians. However, in order to draw actionable conclusions from VR, it is important to ...
    • Weather Camera 

      Palmer, Matthew; Gibbons, Ronald B. (National Surface Transportation Safety Center for Excellence, 2019-11-18)
      Fog- and weather-related visibility reduction is a common cause of multiple-vehicle crashes. Large differential speeds and a tendency of vehicle operators to drive faster than is safe can lead to terrible crashes. Fog can ...
    • Work Zone Lighting’s Effect on Driver Visibility 

      Bhagavathula, Rajaram; Gibbons, Ronald B. (National Surface Transportation Safety Center for Excellence, 2019-06-05)
      Portable light towers are a significant source of glare to motorists entering a work zone. Although existing research has evaluated the effect of light tower orientation on visibility and glare, the effects of factors like ...
