From GPS Points to Travel Patterns: Flexible and Semantic Trajectory Generation with LLMs
Researchers propose HTP, an LLM-based framework that generates realistic urban trajectories by first synthesizing travel patterns and then GPS points, addressing privacy concerns in smart city applications. The method outperforms existing approaches by 29.78% and can generate variable-length trajectories under multiple conditions, advancing synthetic data generation for urban analytics.
