Dr. Agarwal has utilized Hardware-in-the-Loop systems to conduct several studies, including evaluation of adaptive traffic control deployments and quantifying the benefits of alternative signal system strategies for corridor preemption. He has developed tools to evaluate pedestrian safety at intersections and to select alternative intersection designs based on operation and safety performance. He also developed guidelines to assess the feasibility of road diet conversions.
Dr. Agarwal received his M.S and Ph.D degrees from the University of Kentucky. Previously, he lectured for undergraduate courses in traffic and transportation engineering within the Civil Engineering Department at the University of Kentucky, and provided workshops and technical assistance with other courses. Dr. Agarwal has also developed online training and certification courses on signal timing and signal systems, which are utilized by several state agencies. Dr. Agarwal has presented at national conferences, including the Transportation Research Board (TRB), and has coauthored several research reports. He is a member of AHB25, which is the TRB Traffic Signal Systems Committee (TSSC), and serves as the chair of the Signal Timing Manual Subcommittee.
