Dr. Hao Liu is a Research Engineer at PATH in Dr. Xiao-Yun Lu's team, where he works on traffic flow modeling and simulation for traffic stream affected by the Corporative Adaptive Cruise Control (CACC) systems. He received his B.S. in Transportation Engineering from Sun Yat-Sen University in China, M.Sc. in Transportation from Research Institute of Highway in China, and Ph.D. in Civil Engineering from University of Cincinnati. His dissertation research focuses on evaluating the effectiveness of Connected Vehicle (CV) technology on the traffic performance regarding mobility, safety and environment. In addition to the CV effectiveness modeling, he has 9 years of experience in microscopic traffic flow modeling, driving behavior modeling, on-road air quality modeling, traffic safety analysis, and traffic simulation software development. He was the major researcher in a U.S. Environmental Protection Agency (EPA) supported project that aims to identify the interactions among the land-use adaptation, the travel demand patterns and the traffic flow operations. The quantified understanding of such interactions are essential to determine the land-use development plans and travel demand management strategies that enable the optimal environment performance of a region. He also participated in a project supported by the Federal Highway Administration (FHWA) and Ohio Department of Transportation (ODOT). In this project, he was in charge of developing a framework for predicting the on-road PM2.5 emissions based on traffic data available from various sources.
