The City Prosperity Index, CPI, set by UN-Habitat, evaluates urban prosperity according to five parameters as productivity, infrastructure development, environmental sustainability, quality of life, and equity/social inclusion. To a greater or lesser extent, these five factors are represented in the street pattern of every city in the world. Streets have multiple functions as the mobility of people and goods, the supply of energy, water, and information, the collection of waste, the growth of trees, plants, insects or birds, the shadow and sun radiation, the bench where to sit, the place to salute and talk with your neighbors, a playground, or the access to the bakery where you buy the bread. In this sense, streets are public and vibrant spaces, which can perform multiple functions and activities.
