A city is smart if it uses technology to make life easier. Imagine a city with traffic lights that know when to change, or buses that show up just when you need them. A ‘Rustbelt’ city feels old and slow, like the factories from long ago are still running, but not many people live there anymore.
Examples
- A smart city has traffic lights that change when cars are coming.
- A Rustbelt city might have old factories with few workers left.
- Smart cities can help you find a free parking spot on your phone.
