Traffic-State Reconstruction and Prediction under Partial Observability

MSC Lab, UGA  ·  Aug. 2025 – Present

A hybrid framework that couples deep learning with traffic flow modeling to reconstruct and forecast traffic states from partial observations.

  • AI models that reconstruct short-term traffic occupancy and flow in urban signalized environments
  • Traffic flow dynamics extend prediction to corridor-level horizons and capture traffic evolution beyond observed data

3D Digital Twin for Closed-Loop Simulation and Control of Autonomous Vehicles

MSC Lab, UGA  ·  Aug. 2025 – Present  ·  Sponsored by DOE, through ORNL

A multi-resolution digital twin integrating SUMO and CARLA for closed-loop simulation of traffic, control, vehicle dynamics, and hardware-in-the-loop.

  • A five-layer (L0–L4) fidelity framework that quantifies the sim-to-real gap across geometry, sensor signals, perception, and behavior, with gap-budget attribution to trace error sources
  • A ROS-free annotation toolkit for real-world multi-sensor logs (six cameras, 3D LiDAR) that auto-seeds 3D bounding boxes, reducing manual labeling to box refinement

Automated Vehicle Trajectory Modeling (IEEE ITSS AV Challenge)

MSC Lab, UGA  ·  Jun. 2026 – Sep. 2026

1st Place among 28 teams

Behavioral modeling of a following automated vehicle — predicting its 20-second future trajectory from the lead vehicle's trajectory and 10 seconds of its own history, evaluated on accuracy, safety, and comfort.
