Yi-Chang James Tsai

Biography

Before joining the faculty at Georgia Tech, Dr. Tsai worked as a senior research scientist in the GIS center at Georgia Tech for 10 years. Since 1997, he has led a research team and worked with GDOT pavement engineers, developing and successfully implementing a large-scale Oracle GIS-based pavement preservation and management system for GDOT to effectively preserve and manage its 18,000-centerline miles of highway for the past 20 years. A series of models and programs developed by Dr. Tsai, including field pavement condition data acquisition, the annual pavement preservation project prioritization and program development, treatment determination model, cost model, and performance forecasting model, and long-term system performance simulation and optimization, have been successfully implemented by the Office of Maintenance of the GDOT. They have resulted very positive impact on GDOT's operations. He has received the innovation award on GIS-enabled Ship Recognition - Innovation Research Grants for Transportation Security in 2007. He was named Chinese Chang Jiang Scholar in 2009 for his international recognition on pavement preservation and management using sensing and information technologies. The Chang Jiang Scholar is one of the most prestigious scholar honors in China.
