• Abstract: Generative agents offer promising capabilities for simulating realistic urban behaviors. However, existing methods oversimplify transportation choices in modern cities, and require prohibitive computational resources for large-scale population simulation. To address these limitations, we first present a virtual city that features multiple functional buildings and transportation modes. Then, we conduct extensive surveys to model behavioral choices and mobility preferences among population groups. Building on these insights, we introduce a simulation framework that captures the complexity of urban mobility while remaining scalable, enabling the simulation of over 4,000 agents. To assess the realism of the generated behaviors, we perform a series of micro and macro-level analyses. Beyond mere performance comparison, we explore insightful experiments, such as predicting crowd density from movement patterns and identifying trends in vehicle preferences across agent demographics.
