arXiv:2606.13835v1 Announce Type: cross Abstract: LLM-based generative agents are increasingly used in urban simulators, yet it remains unclear whether they reproduce empirically realistic human mobility patterns or merely generate plausible mobility narratives. We introduce a validation framework for evaluating the mobility of generative agents of LLM-based urban simulators against real-world mobility data. For this, we use mobility laws, temporal rhythms, network motifs, semantic activity transitions, and behavioral mobility profiles. Using datasets from the Greater Paris region and Shanghai
The rapid development and application of LLMs in generative agents for urban simulation necessitates rigorous validation against real-world data to ensure their utility.
Evaluating the realism of LLM-based simulations is critical for urban planning, policy development, and understanding complex human-AI interactions, moving beyond mere plausibility to actionable insights.
The focus shifts from simply demonstrating LLM agent capabilities to establishing robust evaluation frameworks that can validate their outputs against empirical reality.
