# Smart City 3D Environment Generation Prompt Create a highly detailed, realistic, and fully explorable 3D smart city designed specifically as the foundation for an intelligent traffic management and road control simulation. The environment should resemble a modern metropolitan city with well-planned infrastructure, realistic road engineering, and an active transportation network. The city should not be based on any specific real-world location but instead combine the best elements of modern urban planning found in advanced cities around the world. The entire environment must feel alive, dynamic, and suitable for demonstrating artificial intelligence, Internet of Things (IoT), autonomous traffic control, emergency response systems, and future smart city technologies. The city should span several square kilometers and include multiple districts connected by an extensive road network. These districts should include residential neighborhoods with houses and apartment buildings, commerci
