Dr. Yao-Jan Wu is an professor of transportation engineering in the Civil and Architectural Engineering and Mechanics Department and the Executive (Founding) Director of the Center for Applied Transportation Sciences (CATS) at the University of Arizona (UA). Currently, Dr. Wu is the faculty advisor of the UA Institute of Transportation Engineers (ITE) student chapter. He has served as the Principal Investigator (PI) or Co-PI of over 50 national/international research projects.


Dr. Wu has more than 160 refereed publications, including more than 70 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, pedestrians, bikes, and climate change).


My research interests highlight a strong connection between information technology (IT) and traditional transportation research. My research  covers four major fields:  1) intelligent transportation systems (i.e. development of advanced traffic detection technology and computer vision applications), 2) large-scale network analyses (i.e. online data management and analysis systems, network performance measurement and traveler behavior analysis), 3) traffic safety (i.e. accident modeling and analysis, and advanced safety vehicles), and 4) Sustainable transportation systems (e.g. climate change impact analysis). More specifically, my research interests are listed as follows: 

  • Intelligent transportation systems (ITS)

    • Image processing and computer vision applications

    • Traffic detection technology development

    • Advanced/information technology applications

  • Data-driven large-scale transportation system analysis and optimization

    • Freeway and arterial operations

    • Transportation system performance measurement

    • Big traffic data management, mining, and analysis

    • Travel behavior and pattern analysis

  • Transportation safety analysis and accident modeling

  • Sustainable transportation systems

    • Sustainable infrastructure

    • Transit system planning and operations
