Fig. 4.16 Umbria region, Italy. Arterial fabrics in the plain
society to be reached. To identify harmony or contrasts between pre-existing and
new forms of land use, 26 landscape contexts have been identified, testifying to
the strong morphological distribution of Umbria (Fig. 4.17). In the different case
studies, areas with wide panoramas alternate with closed, hidden, and remote
areas; from general, all-inclusive reading to observations of individual items on
the urban design scale, in which identifying elements and signs assume strong
significance with respect to an overall glance and give strength to strongly cohe-
sive places (Fig. 4.18). The research has lingered on this relationship on the
basis of the following parameters:
Density , keeping in mind that everything functions mostly by accumula-
tion and continuous addition, not by composition (Fig. 4.19a, b).
Flexibility , considering the kind of continuous oscillation in mobility that
encompasses every urban planning event (Fig. 4.20a, b).
Casuality , which distinguishes the juxtaposition of functions and forms
(Fig. 4.21a, b).
Alternation , identifying land uses and consumption that are intensive and
strong in some parts of the city and rarefied, indecisive, or nonexistent in
others (Fig. 4.22a, b).
Differences , always to be evaluated, since they carry identifying value
(Fig. 4.23a, b).
