3. Configurational techniques

massimiliano petri
Common elements
The assumption of the urban grid as the model input
The assumption of connection between spatial elements
as the basis for the appraisal of configuration
Distinguishing elements
The way of reducing the urban grid into a system
The definition of the spatial elements of the system

4. The configurational techniques
valerio cutini
giovanni rabino
The way of reducing the urban grid into a system is the
distinguishing element of the several operational techniques
axial analysis visibility graph analysis
spatial
lines vertices
elements
connection elements points uniformly distributed all
between convex spaces over the grid
relation intersection mutual visibility
system axial map visibility graph

system A set of singular points, called mark points
element The mark point, selected as
turning point of centre-road lines
Intersection point between centre-road lines
central points of squares
access point to squares
maximum lenght point within straight centre-road lines
slope variation point within centre-road lines

19. Conclusions
valerio cutini
giovanni rabino
3D Ma.P.P.A. actually carries configurational analysis
into the third dimension, taking orography into account
The three-dimensional extension of Ma.P.P.A. provides
results that appear so brilliant as to (slightly) improve
those of the existing techniques
3D Ma.P.P.A. actually integrates and completes
Ma.P.P.A., which can be assumed as a particular case,
lighter on a computational regard and hence suitable for
flat settlements
