ABSTRACT
Arteries devoted to sustain streams of users, resources and debris, are
a foremost factor and pre-condition of the development of urban areas and of the
transformation of landscapes. Roadscapes reflect outcomes related to super
urbanization tendencies. Often conceived as isolated tubes, roads cut and
obscure form, structure, biotic and abiotic factors of sites, urban fabrics and
spaces. A broad vision of landscape is a basis for reconceiving roads. The
concept of road-spine emerges: the road is conceived as the basis of a bundle
of routes, nodes, surfaces, poles and tiles, devised to frame and shape a
mosaic of open spaces, crops, farms, stores, basins and service areas. The road-spine
entails the idea of a permeable infrastructure devised to integrate diverse
functions: from serving various forms of motion, by ordering an isotropic grid
of routes, to framing a porous urbanscape; from disposing surfaces meant to
preserve biocenosis and biotopes, to favoring osmosis amid land uses. It also prefigures
a distribution of land uses dependent on site vocations, and a mosaic of
scenarios open to encounter, evasion, rest, amusement, participation, and to spontaneous
practices of space.
