    • 3D Virtual Sight Distance Analysis Using Lidar Data 

      Olsen, Michael J.; Hurwitz, David S.; Kashani, Alireza G.; Buker, Kamilah (2016)
      This research project investigated advanced safety analysis methodologies for drivers’ sight distance based on high resolution data acquired using lidar (light detection and ranging) technology. Sight distance analyses ...
    • A Platform for Proactive Risk-Based Slope Asset Management - Phase II 

      Cunningham, Keith; Olsen, Michael; Wartman, Joseph; Dunham, Lisa (2015)
      The lidar visualization technique developed by this project enables highway managers to understand changes in slope characteristics along highways. This change detection and analysis can be the basis of informed decisions ...
    • Rendering of Dense, Point Cloud Data in a High Fidelity Driving Simulator 

      Hurwitz, David S.; Olsen, Michael; Marnell, Patrick; Mahmoudabadi, Hamid (2014)
      Driving Simulators are advanced tools that can address many research questions in transportation. Recently they have been used to advance the practice of transportation engineering, specifically signs, signals, pavement ...
    • Transportation Corridor Resiliency in the Face of a Changing Climate 

      Cunningham, Keith; Olsen, Michael J.; Wartman, Joseph; Leshchinsky, Ben; O'Banion, Matt (2018)
      The effects of a changing climate on transportation corridor slopes are poorly understood, but several recent studies have suggested that landslide activity, especially rockfall, is likely to increase as a consequence of ...
    • Unmanned Aircraft System Assessment of Landslide Safety for Transportation Corridors 

      Cunningham, Keith; Olsen, Michael J.; Wartman, Joseph (2016)
      An assessment of unmanned aircraft systems (UAS) concluded that current, off-the-shelf UAS aircraft and cameras can be effective for creating the digital surface models used to evaluate rock-slope stability and landslide ...
