Evaluating the functional performance of the road network depending on its structure in the residential district (Homs City as an example)

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 other 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).
