This research has been implemented in Homs city-Syria, in order to study the
configuration of the road network in residential district, and the debates about the most
efficient pattern in terms of functional performance, treeor grid pattern, or oth
er patterns.
In order to do that, it focused on the planning principles of functional performance, which
can be summarized to:( proximity, permeability, security). And worked on identifying
Accurately the functional performance indicators, and there measuring method, and they
were (Cell / Cul ratio – T / X ratio- distant between the center and the periphery - number
of cells per unit area –hierarchy). And applied it on the case studies: (organized / newly
planned residential districts). It turns out that the road network should have a medium
proximity and permeability for traffic,while it should be high for pedestrian. Therefore,the
network patternCandidate forbetterfunctional performance when it's nearly in the mid-way
between (tree and grid).
