A Technological Framework for Achieving the SDGs

The primary barrier to effective urban management is often fragmented data and siloed systems. A unified technological framework utilizing OpenUSD and digital twins provides a solution by creating SimReady environments for testing and optimization. This approach directly supports the creation of resilient infrastructure and sustainable urbanization as outlined in the SDGs.

Three-Stage Workflow for Proactive Urban Management

1. Simulation: Utilizing platforms like NVIDIA Cosmos and Omniverse, cities can generate synthetic data and simulate complex “what if” scenarios. This capability is crucial for planning resilient infrastructure (SDG 9) and preparing for climate-related events (SDG 13).
2. Training: The generated data is used to train and refine vision AI models, creating intelligent systems capable of understanding and interpreting the urban environment. This fosters innovation required to meet sustainability targets.
3. Deployment: AI agents are deployed using platforms like NVIDIA Metropolis for real-time video analytics. This enables a shift from reactive problem-solving to proactive management, a core tenet of sustainable city planning (SDG 11).

This workflow allows for the convergence of disparate data sources, such as weather data and traffic sensors, into a cohesive operational platform. This supports real-time monitoring and strategic planning, which are essential for building sustainable and inclusive communities.
