Answer
Hello, Mohammad;

Iran is a very beautiful AND large country at 1.648 million sq. km.

From the lowest point at the Caspian Sea (-28 m) to the highest point at Kuh-e Damavand (5,671 m)  the range of climate type is extreme, from arid and semiarid to sub-tropical, along Caspian coast.   All this to say, be sure and pick the right kind of plants for your climate area!

There are different design criteria for urban, suburban, or rural settings.  I will assume that since you are spanning such a distance, it is rural in nature.

Here is a good basic guide for a streetscaping.  Look toward the bottom for other design criteria:

As to general "streetscaping" ideas, availability of water is crucial.  44 km. is quite a distance, so picking the right plants for survivability and long-term maintenance is important.  If you do not have a large staff to maintain this design, you'll want plants that do not need extra care. All plants need some attention now and then, but why create a 44 km. problem by choosing the wrong plants?

Three plants deep would be a minimum for either a median or road-side.  Also consider gaps for pedestrian crossings, if this is to be installed in an urban area.

At curves in the road or at road intersections, be aware of the ability of cars and pedestrians being able to see one another.  Keep the shrubs from growing up to high (no more than 0.5m), and keep the trees trimmed up (no branches lower than 2m) at these critical locations.

These are only basic ideas.  Good luck!  ~Marc
