    • Vehicle Occupants and Driver Behavior: A Novel Data Approach to Assessing Speeding 

      Martin, Michael W.; Green, Lisa L.; Shipp, Eva; Chigoy, Byron; Mars, Rahul (SAFE-D: Safety Through Disruption National University Transportation Center, 2019-11)
      The question of whether driver behavior, and speeding in particular, differs based on passenger(s) presence requires the use of large amounts of data, some of which may be difficult to accurately obtain. Traditional methods ...
    • Vehicle Operating Speed on Urban Arterial Roadways 

      Fitzpatrick, Kay; Das, Subasish (Safe-D: Safety Through Disruption, 2019-01)
      This research explored (1) the relationship between suburban vehicle operating speed and roadway characteristics,especially the presence of bicyclists and (2) whether crowdsourced speed data could be used to estimate ...
    • Video Based Validation of a Maneuver Classification Algorithm for Naturalistic Driving Data 

      Hargutt, Volker; Landau, Andreas; Metz, Barbara; Neukum, A. (2014-08-25)
    • 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 ...
    • Video-Based Measure Of Driver Heart Rate For Naturalistic Driving Data 

      Kuo, J.; Koppel, S.; Charlton, J. (2014-08-25)
      Internal driver events such as emotional arousal do not consistently elicit observable behaviors. However, heart rate (HR) offers promise as a surrogate measure for predicting these states in drivers. Imaging photoplethysmography ...
    • Virginia Connected Vehicle Test Bed System Performance (V2I System Performance) 

      Viray, Reginald; Sarkar, Abhijit; Doerzaph, Zachary R. (Connected Vehicle/Infrastructure University Transportation Center (CVI-UTC), 2016-05-01)
      This project identified vehicle-to-infrastructure (V2I) communication system limitations on the Northern Virginia Connected Vehicle Test Bed. Real-world historical data were analyzed to determine wireless Dedicated Short ...
