Relevance of street patterns public space CoverUN-Habitat has carried out, through affordable geographic information systems, an estimation of the public space allocated to the street in different cities of the world. The number of street crossings has also been counted, as an indicator of the form and pattern of the street layout.

In this exercise, the rest of the public space, like gardens and general public spaces for amenities, including sports, are not taken into account. This was done in order to have a clear view of the size of the public space allocated to connectivity and commercial sidewalks, related to the quality of the street life.

The methodology of data collection has been through open source software, which provides, on the one hand ease of access, but for more precision, other more sophisticated software is needed.

Nevertheless, even at these levels of precision, very interesting patterns emerge. With this information, a more efficient street pattern is highly recommended, especially at the initial moment of urban growth.

Building Hyperdensity and Civic DelightHyperdensity — defined as density sufficient to support subways — contributes to the health, prosperity, and sustainability of cities, the densification of our built and social environments will to a large extent determine our strength as a nation. Compared to most forms of human habitation, dense cities are the most efficient economic engines; they are the most environmentally sustainable and the most likely to encourage joyful and healthy lifestyles. So, how do we build delightful cities that make us more prosperous, ecological, fit and equitable? Here I wil lay out the factors that impede hyperdensity in our cities today, and the conditions necessary to create hyperdense environments in the future, including great design, responsible preservation and sound urban planning.
