Issue 63 of JA magazine projects possible pathways of development for Tokyo, Created by Prof. Ohno Hidetosh and his laboratory at the Univesity of Tokyo, it aims to create a new planning paradigm that will address environmental problems and demographic changes. The idea of the 'Fibercity' is adopted, describing structures that extend in a linear fashion such as transportation and communication networks - basically referring to speed and movement. This challenges the harmonious atomic model of traditional Western planning by recognising that mobility is now the central characteristic of conurbations and proposing exchange and interaction rather than production as the basis for structure.
The 'Fibercity' concept extends into four urban design strategies, Green Finger, Green Web, Green Partition and Urban Wrinkes, each of which project an attempt to change Tokyo by manipulating spatial fibres. The journal describes and illustrates these strategies in detail, as well as showing various historic, contemporary and projected aspects of Tokyo.
While as a sprawling metropolis Tokyo has a different set of circumstances, many of the design strategies could also be applied to Helsinki. Aspects of these design strategies echo Alexander's Pattern Language - eg number 3 City Country Fingers.
The Fibercity web site describes a Fiber as follows:
"A Fiber can be understood as an organizing grain or thread, in terms of city form it is a linear space."
"Fibers are spaces with velocity."
"Each of four urban strategies for the realization of the fiber city, namely Urban Wrinkle, Green Web, Green Partition and Green Finger is a strategy for altering the character of the city through careful manipulation of existing linear elements, or fibers. It should be noted however that these strategies are not only aimed towards a single purpose, but rather address several interrelated objectives, including: the reactivation of the city, disaster mitigation, amendment of transportation policy, and the enrichment of green space."
"Fiber City is flexible like fabric, made up of many textures, and upon inspection consists of repeating analagous patterns of different scales that have a fractal character."
