This week saw big steps in using AI to make cities smarter. Cities worldwide are rolling out new AI-driven traffic systems that help reduce jams and make roads safer. These systems watch traffic in real-time and suggest better routes.

Many places are also building net-zero buildings that use AI to save energy. These smart buildings adjust heating and cooling automatically to cut waste.

Waste and water systems got smarter too with AI helpers that predict when trash bins need emptying or when pipes might leak. This saves money and keeps cities cleaner.

New urban IoT platforms linked entire city services using 5G networks. This lets workers fix problems faster by seeing data from streets, lights, and buses all in one place. The goal is to fight climate change while improving daily life.
