3.1.2. Array structure
An array structure organizes the urban growth in between the spaces left by the crossing of two sets of axes (normally perpendicular).
· Maximal densification.
· Allows multiple routes from one point to the other.
· Wheeled access for regeneration to the inner fabric depends on both axes being accessible by building machinery.
· Increments the “corridor” surface.


An array structure is decided but instead of a set of perpendicular axes crossing between them and providing squared spaces for the urban fabric to be developed, a set of circular wheeled routes define the inner spaces. The circular rings are set up in rows, establishing a sort of circular array of roads.

In order to allow fast transportation between one side to the other of the Gen II, linear axes cross the circular array.

This first order of rings is established on a 100m basis. They will work in different levels. For Gen 1.5, just one or two rings will be necessary to allocate the buildings needed; the ring then will work on the ground level, providing surface transportation and access between the buildings.  Further on when more rings are incorporated to the system, an underground level ring system will provide small wheeled transportation by electrical car, while the ground level will remain as heavy traffic transportation system.

When Gen II is growing to a larger city, bigger rings will circumvallate the existing rings, establishing faster connections between different parts of the community. These new set of rings will have larger traffic capabilities, allowing bigger number of electrical cars in the underground level and will provide other transportation systems such as elevated tramway on the surface level. These new rings will come together will crossing axes that will allow direct connection by electrical car.

In this scheme the urban fabric is established almost randomly inside the circular pattern. The ring transportation system becomes the larger order of the city. This is due to the fact that several construction systems and building shapes need to be deployed as it is difficult to asset which one will be the most effective. Therefore, a neutral structure that allows any type of building in its interior is a more flexible choice.
