TrajGenAgent: A Hierarchical LLM Agent for Human Mobility Trajectory Generation
Researchers introduce TrajGenAgent, an LLM-based framework that generates realistic synthetic human mobility trajectories without model fine-tuning by combining hierarchical agent design with deterministic workflows. The approach addresses privacy and cost constraints in trajectory data collection while maintaining semantic coherence and behavioral realism.
