Understanding how cities have been planned over time can help us design better cities for the future. Here are some important points to consider:

1. Changes Over Time:

   • Urban planning has changed a lot since ancient days.
   • For example, cities were designed in straight lines during Roman times.
   • Later, during the 19th century, there was the garden city idea.
   • Famous city designs include New York City's grid layout from 1811 and the circular design of Paris, created by Baron Haussmann in the mid-1800s.

2. Population Growth:

   • From 1950 to 2020, the number of people living in cities around the world jumped from 746 million to about 4.3 billion.
   • This shows a big need for cities that are planned well.
   • Research shows that cities with good planning can help people spend 20% less time commuting and can lower crime rates by 10%.

3. What We’ve Learned:

   • Looking at history teaches us that having mixed-use areas, where people can live, work, and play, is very important.
   • Walkable neighborhoods and green spaces also improve the quality of life in cities.
   • By learning from past mistakes, like the problems caused by urban sprawl, we can create more environmentally friendly city designs.
