Michigan Traffic Lab


University of Michigan

The Director of Michigan Traffic Lab, Prof. Henry Liu, is a Bruce D Greenshields Collegiate Professor in the Department of Civil and Environmental Engineering and the Director of Mcity at the University of Michigan, Ann Arbor. He is also a Research Professor at the University of Michigan Transportation Research Institute and the Director for the Center for Connected and Automated Transportation (USDOT Region 5 University Transportation Center). From July 2017 to August 2019, he took a leave of absence from the University of Michigan and served as Chief Scientist on Smart Transportation for DiDi, one of the leading mobility service providers in the world. While he was with DiDi, he led and managed the Smart Transportation Business Unit. Prof. Liu received his Ph.D. degree in Civil and Environmental Engineering from the University of Wisconsin at Madison in 2000 and his Bachelor degree in Automotive Engineering from Tsinghua University (China) in 1993. Prof. Liu conducts interdisciplinary research at the interface of transportation engineering, automotive engineering, and artificial intelligence. Specifically, his scholarly interests concern traffic flow monitoring, modeling, and control, as well as testing and evaluation of connected and automated vehicles. Professor Liu has nurtured a new generation of scholars, and some of his PhD students and postdocs have joined first class universities such as Columbia University, Purdue University, RPI, etc. Prof. Liu is the managing editor of Journal of Intelligent Transportation Systems.

Xiaowei(Tom) Shi will join the Civil and Environmental Engineering at the University of Wisconsin - Milwaukee as an Assistant Professor in Fall 2023. Before joining University of Wisconsin - Milwaukee, he worked as a Postdoctoral Research Fellow at the University of Michigan with Prof. Henry Liu. 


Our research work published in Nature, March 23, 2023 Issue is covered by The Wall Street Journal


The paper titled "Learning naturalistic driving environment with statistical realism" is published in Nature Communication by Professor Henry Liu and Xintao Yan. This is the first time that a simulation model can reproduce the real-world driving environment with statistical realism, particularly for safety-critical situations.
