đź’¬ About Me
I am currently a Postdoctoral Researcher at the College of Transportation Engineering, Tongji University. I received my Ph.D. degree in Transportation Engineering from Tongji University in May 2025, with the thesis titled “Sociality-Aware Interactive Motion Planning for Autonomous Driving”.
From Nov. 2022 to Oct. 2023, I was a visiting scholar at the Technical University of Dresden (TU Dresden), Germany, under the supervision of Prof. Meng Wang.
I have published over 20 papers in top journals and conferences such as IEEE T-ITS, AA&P, and Scientific Data. I won the Champion of the 2022 CommonRoad Motion Planning Competition for Autonomous Vehicles and the Silver Medal at the 2023 International Exhibition of Inventions of Geneva. I was awarded the IEEE ITSS Initiative Project. Since 2024, I have served as a workshop chair, organizing and hosting the “Human-Machine Interaction” workshop at the IEEE ITSC International Conference.
Research Interests
- Interactive Motion Planning
- Modeling Social Driving Behaviors

📝 Selected Publications

InterHub: A Naturalistic Trajectory Dataset with Dense Interaction for Autonomous Driving
Xiyan Jiang, Xiaocong Zhao*, Yiru Liu, Zirui Li, Peng Hang, Lu Xiong, and Jian Sun
- A naturalistic driving dataset with dense interactions is extracted from multiple widely adopted public driving datasets, being unified, analyzed, and categorized to provide a user-friendly data foundation.
- A quantitative-yet-readable definition of the driving interaction using the formal method is proposed along with an open access toolkit.

Towards Interactive Autonomous Vehicle Testing: Vehicle-Under-Test-Centered Traffic Simulation
Yiru Liu, Xiaocong Zhao*, Jian Sun
- This study introduces an Vehicle-under-test-Centered environmental Dynamics Inference (VCDI) model for realistic, interactive, and diverse background traffic simulation.

Measuring Sociality in Driving Interaction
Xiaocong Zhao, Jian Sun*, Meng Wang
- We introduce a novel framework designed to analyze social behaviors through driving trajectories.
- By understanding and quantifying social patterns in natural driving interactions, we demonstrate the potential to enhance autonomous driving technologies by incorporating human strategies in expressing sociality.
