Dr. Karkee is an Assistant Research Scientist at the Texas Transportation Institute. He holds a Doctor of Philosophy in Civil and Environmental Engineering from the University of Nevada, Las Vegas, a Masters degree in Civil Engineering from Asian Institute of Technology (Thailand), and a Bachelor's degree in Civil Engineering from Tribhuvan University (Nepal). He is a licensed Civil Engineer in Nevada since December 2003. Prior to joining TTI in April 2006, Dr. Karkee worked as a research assistant with the University of Nevada Las Vegas, Transportation Research Center in a pedestrian safety research project funded by the Federal Highway Administration. The main goal of the project is to improve pedestrian safety and walkability within the urban boundaries of the Las Vegas metropolitan area.
Dr. Karkee specializes in traffic safety and evaluating traditional and innovative safety strategies. In his dissertation research, he evaluated countermeasures intended to motorists and pedestrians. Several measures of effectiveness were identified to compare motorists and pedestrians behavior.
Since joining TTI, Dr. Karkee has been involved with many research and implementation projects related to traffic operations, traffic simulation, traffic safety, evaluation of innovative technologies, incident management, and access management. Dr. Karkee has been actively involved in supporting various TxDOT districts, including San Antonio, Austin, Corpus, Pharr, and Laredo. His most recent research work involves supporting research studies for guidelines for applying managed lane strategies to ramps. He is currently working on a research project to evaluate speed activated displays on curves; these devices will be deployed in four southern districts of the TxDOT. Dr. Karkee's professional affiliation includes the Transportation Research Board (TRB) and the Institute of Transportation Engineers (ITE).
