At the Smart City Expo World Congress in Barcelona, NVIDIA introduced breakthroughs that are reshaping what’s possible for cities. This new approach, called Physical AI, blends digital twins, synthetic data, and real-time AI vision to help cities better understand, manage, and improve urban life. These connected technologies are quickly becoming the foundation for smarter, safer, and more responsive cities.
The Heart of NVIDIA’s Physical AI
NVIDIA’s Physical AI brings several advanced technologies together into a powerful ecosystem. Each is designed to help cities see more, know more, and act faster:
- NVIDIA Omniverse: Builds true-to-life, interactive models of whole cities so planners and engineers can test changes before they happen in the real world.
- NVIDIA Cosmos: Produces vast amounts of synthetic data—artificially generated but realistic scenarios—to train AI to handle every kind of urban challenge.
- NVIDIA NeMo: Refines and adapts AI language and vision tools so they can understand the unique problems of busy city environments.
- NVIDIA Metropolis: Delivers instant analysis of video feeds from cameras and sensors, spotting what matters fast and turning raw data into action.
All of these technologies come together in the NVIDIA Omniverse Blueprint for Smart City AI. This framework guides city developers and planners as they design, test, and launch new AI solutions. Whether it’s traffic control, energy management, or public safety, this blueprint helps city teams experiment safely in a digital world before rolling out solutions for real people.
Turning Innovation into Action
NVIDIA’s Physical AI is no longer just an idea—it’s at work in cities across the world:
- In Raleigh, North Carolina, geospatial AI agents watch over traffic, public spaces, and infrastructure in real time. They can quickly spot problems, create detailed reports, and alert human operators. This reduces fatigue and helps teams respond where and when they’re needed most.
- In Asia, places like Ho Chi Minh City and Kaohsiung, Taiwan are already seeing results. Kaohsiung’s systems, powered by NVIDIA, can analyze up to 50,000 video streams at once, guided by generative AI capable of “narrating” complex events like floods or accidents as they happen.
These advances help city teams take charge in moments that matter—keeping people safe and informed when every second counts.
The Power of Partnership
What makes NVIDIA’s approach unique isn’t just the technology—it’s the spirit of collaboration. Industry leaders are working side by side with NVIDIA to shape the cities of tomorrow:
- Milestone Systems is creating Project Hafnia, the world’s largest collection of real-world video data, and using NVIDIA’s AI to build smarter traffic and transport solutions.
- Akila and BizzTech are merging interactive 3D city models with cutting-edge AI agents. This combination helps cities see situations from every angle and make decisions more quickly and wisely.
With partners bringing their expertise, new tools can be tested and deployed at scale, reaching more communities—faster.
Why This Matters Now
Worldwide, city populations are set to double by 2050. With more people come more complex challenges: traffic, sustainability, safety, and the need for fast decisions. Physical AI opens up vital possibilities:
- City planners can run simulations before making real changes, avoiding costly mistakes.
- Operators get a live, intelligent view of what’s happening so problems are fixed before they grow.
- Automation takes care of routine monitoring, freeing people to focus on priorities—and reducing errors.
- Solutions can scale from small tests to whole-city rollouts.
This is not just about machines doing more—it’s about giving city leaders the insight and tools to create safer, cleaner, and more livable places for everyone.
Looking Ahead
NVIDIA’s Physical AI ecosystem marks a turning point for urban living. By combining digital twins, synthetic data, and vision AI, cities can now prepare for the future with intelligence and care. With these technologies rolling out in more cities, everyday life will be safer, more efficient, and more responsive. The transformation has begun—one city at a time.
