Dr. Yao-Jan Wu is an associate professor of transportation engineering and the Director of Smart Transportation Lab in the Civil and Architectural Engineering and Mechanics at the University of Arizona (UA). Before joining the UA, Dr. Wu was an assistant professor at Saint Louis University (2011~2013) and postdoc at the University of Virginia (2011). He has served as the Principal Investigator (PI) or Co-PI of more than 20 national/international projects. Dr. Wu has more than 100 peer-reviewed publications, including more than 40 journal publications. He has presented his research findings more than 100 times at national and international conferences, and invited speaker events. Dr. Wu’s research interests highlight a strong connection between information technology (IT) and traditional transportation research. His research broadly covers four major fields: 1) intelligent transportation systems (e.g., advanced traffic detection technology, sensor data quality control, and computer vision applications), 2) data-driven large-scale transportation system analysis and optimization (e.g., freeway and arterial operations, system, traffic data management, mining, and analysis, and traveler behavior analysis) , 3) traffic safety (e.g., accident modeling and analysis), and 4) sustainable transportation planning (e.g., transit and climate change).
