About

Multimodal Traffic Large Language Models for Intelligent Expressways

I am a Ph.D. student in Civil and Hydraulic Engineering, specializing in transportation, at South China University of Technology. I am also supported as a joint Ph.D. student through the Overseas Study Program of the Guangzhou Elite Project.

My research focuses on multimodal domain-specific large models for intelligent expressways. I study how visual, traffic flow, ETC, and structured traffic data can be jointly modeled to improve traffic perception, understanding, prediction, and decision-making in complex expressway environments.

Research focus

Multimodal traffic intelligence for smarter expressways.

My research lies at the intersection of transportation engineering, multimodal learning, and domain-specific large models.

02

Multimodal traffic data fusion

Integrating visual, traffic flow, ETC, temporal, and structured traffic data to build unified representations of expressway traffic conditions.

  • Vision + traffic flow
  • ETC data
  • Temporal modeling
03

Intelligent expressway perception and understanding

Building reliable methods for traffic state perception, congestion recognition, cause understanding, and future traffic forecasting under complex real-world conditions.

  • Traffic perception
  • Congestion understanding
  • Expressway forecasting
