Qing Cai

I am a research assistant professor in the Department of Civil, Environmental, and Construction Engineering at the University of Central Florida. I received my PhD degree from the University of Central Florida advised by Prof. Mohamed Abdel-Aty, and my Master degree and Bachelor degree from Tongji University.

My research focuses on the applications of emerging technologies and methodologies for intelligent transportation system in smart cities, developing machine learning and modeling solutions to understand the effects of built-in environment on transportation safety and efficiency, and innovating software/hardware and simulation development to advance transportation systems for connected & automated vehicles (CAVs). I rely on the real-world data and simulation data to better understand how to adapt our current transportation system to the future. I have published over 40 journal papers and worked on over 10 research projects.
