5. Irregular Plans
This plan does not have a
system of organisation.
The streets are winding with
dead-ends, alleyways and
courtyards.
Muslim cities and the older
parts of town in European
cities are examples of this
type of plan.
These areas often contain
sites of historic interest.

17. Grid Plans
This plan in the most common,
as it uses a simple grid shape
with perpendiuclar streets.
This design is based on Greek
and Roman cities and was also
used in European cities in the
19th century.
It is easy to extend, but it is not
suitable for all types of relief.
Also, the perpendicular streets
do not favor the smooth flow of
traffic, so diagonal
thoroughfares are required.

23. Radio-centric Plans
In this plan, streets are organised
in concentric circles around a
central point. Examples of cities
with this plan iclude Paris,
Moscow, Milan and Madrid.
The radial routes allow vehicles to
reach the city centre quickly, but
moving from one side of the city to
other can be difficult, requiring
travellers to go through the
congeste city centre.
This problema can be solved by
creating roads that connect these
areas in the form of concentric
circles.
