Vikash V. Gayah is a Professor of Civil Engineering at The Pennsylvania State University, where he joined the Department of Civil and Environmental Engineering in 2012. He currently serves as the interim director of the Larson Transportation Institute. Dr. Gayah has established himself as a leading researcher in transportation engineering with significant contributions to traffic flow theory and urban mobility.
His educational background includes B.S. and M.S. degrees from the University of Central Florida (2005 and 2006) and a Ph.D. from the University of California, Berkeley (2012). His research primarily focuses on urban mobility, traffic operations, traffic flow theory, public transportation, and traffic safety, employing analytical models, micro-simulations, and empirical data analysis.
Dr. Gayah's research on left-turn restrictions at intersections has shown significant safety and efficiency benefits, demonstrating that eliminating left turns can reduce crashes (which account for 61% of intersection collisions), improve traffic flow, and decrease fuel consumption by 10-15% per trip. His work on bus route reliability has explained the mathematical causes behind bus bunching and proposed solutions using real-time tracking and control algorithms.
He has been recognized with numerous awards including the prestigious CAREER Award from the National Science Foundation, the Gordon F. Newell Award for Excellence in Transportation Science, and the Harry West Teaching Award. Dr. Gayah serves on the editorial boards of Transportation Research Part B and Part C, and is an associate editor for the IEEE Intelligent Transportation Systems Magazine.
His research has been funded by multiple State Departments of Transportation, the US Department of Transportation, Federal Highway Administration, National Cooperative Highway Research Program, and National Science Foundation. Dr. Gayah has authored over 45 peer-reviewed journal articles and 50 conference proceedings, establishing himself as a significant contributor to transportation engineering knowledge.
