CityPlanner framework enables executable urban planning with feedback loops

Researchers have introduced CityPlanner, a novel sandbox-agent framework designed for executable urban planning tasks. This system utilizes UrbanSandbox, a file-based environment that allows agents to generate, evaluate, and revise plans based on executable feedback. To enhance learning efficiency, CityPlanner employs atomic-task reinforcement learning, separating initial plan construction from feedback-driven refinement. Experiments demonstrate that CityPlanner surpasses existing heuristic, task-specific reinforcement learning, and general large language model-agent baselines on real-world urban planning benchmarks.
