There are three main types of city layouts: orthogonal/grid plans which consist of straight, wide streets crossing at right angles in a checkerboard pattern; radiocentric plans with streets radiating out from a central point and forming concentric circles; and irregular plans without a defined geometric shape formed by short, narrow streets of irregular layout. Examples of grid and radiocentric plans include Barcelona and an unnamed city, while Córdoba demonstrates an irregular layout.

4. • ORTHOGONAL PLAN
• GRID PLAN
• CHECKERBOARD
This plan consists of
straight, wide streets
that cross at right
angles.

5. An example of grid plan: Barcelona

6. • RADIOCENTRIC PLAN
This plan consists of
central point from
which streets radiate,
like the spokes of a
wheel, crossed by
others that form
concentric circles.

8. • IRREGULAR PLAN
This plan does not
have a defined
geometric shape and
is formed by short,
narrow streets and
alleys of irregular
layout.
