The article explores how different urban planning strategies affect the layout of cities, focusing on the idea of having multiple centers of activity. By using data and computer simulations, the researchers found that where jobs are located in a city can change how the city is structured. They also discovered that the physical layout of a city is closely connected to how different parts of the city interact with each other. This shows that urban planning plays a big role in creating a sustainable and well-organized city. The study suggests that using planning tools can help city planners make better decisions about how to shape cities with multiple centers of activity.
