There are four elements that you need to understand for the building, proliferation and networking of a city:
1. The city is comprised of standardized parts arranged on a matrix. These parts are the standard equipment included in the container of each city and are easily identifiable.
2. The city is organized according to a series of general principles which are socially, culturally and politically determined, and in most cases are manifested in clear architectural and urban examples.
3. The city is the relationship of constantly changing flows superimposed onto a generic template.
4. You will have the ability to customize your city according to local topographical, climactic or cultural conditions.引自 How to build a city
