Short Biography

Dr. Songchitruksa holds Ph.D., M.Eng., and B.Eng., all in Civil Engineering, from Purdue University, Asian Institute of Technology, and Chulalongkorn University respectively. He joined the Texas Transportation Institute (TTI) in January 2005 after serving as an assistant professor (tenure-track) in the Department of Civil Engineering at Texas A&M University at Kingsville (TAMUK). Dr. Songchitruksa is a registered professional engineer in the State of Texas.

Dr. Songchitruksa¿s areas of expertise include traffic operations, traffic simulation, traffic safety, intelligent transportation systems (ITS), and advanced statistical methods. His research is mainly to improve safety and efficiency of traffic operations through the integrated use of new technologies in traffic simulation and ITS data collection and advanced methods for transportation data analysis. During his tenure with TTI, Dr. Songchitruksa has involved as a principal investigator and a key researcher in a number of research projects specializing in the areas of traffic operations and control, freeway operations, incident management, traffic simulation, and safety modeling and analysis. Prior to joining TTI, he was a faculty member at TAMUK teaching and advising both undergraduate and graduate engineering students.

Dr. Songchitruksa has over a decade of professional experience in transportation research. He has been actively involved with Transportation Research Board committees AHB25 (Traffic Signal Systems) and ANB20 (Safety Data Analysis and Evaluation). He has published a number of articles in refereed journals and peer-reviewed conference proceedings.
