Cities around the world are using artificial intelligence to plan better and move smarter. In this weekly update, we see major changes happening in urban planning and infrastructure. AI agents are being used in traffic systems that automatically adjust to real-time conditions, digital twins are helping cities test ideas before building them, and communities are preparing for massive data center projects that power AI technology. For example, in the United States, the government is offering $112 billion to rebuild Gaza as a smart city with AI-optimized infrastructure. Meanwhile, the town of Wellesley in Massachusetts is expanding its use of AI to help with planning, budgeting, and public engagement. These AI tools help city leaders make faster decisions and design streets that work better for people. However, there are important questions about environmental impact. Data centers that run AI technology use enormous amounts of electricity and water, creating pollution concerns that communities must carefully plan for. Cities from New Albany, Ohio to Singapore are learning that with good planning, AI infrastructure can create jobs, grow communities, and deliver long-term benefits.
