Socio-aesthetic forces are among the most influential determinants of urban form in present day society. These forces derive from a brief period of history still dominated by the Romantic, Picturesque, point of view. Regional and urban planners, victims of this aesthetic approach, currently provide fixed solutions and unmanoeuvrable transportation networks.An evolving society requires a network system that can respond to its development. The multivariate system of network reserves, justified in this paper, claims a capability of maximum response to change, with maximum adaptability to existing urban forms. It calls, however, for an espousal of monotonic socio-aesthetic principles opposed to those at present endemic in society.
