Explaining physical morphological components in urban space(Study sample: Gheytariyeh neighborhood of Tehran city)

Morphology examines the cities as the human resorts, which contain form. The morphologists study the process of urban development as well the progression of the morphologic element. The buildings, land development, streets, and texture structures are considered as the main elements of urban morphology. The main question is whether changes in morphology will lead to improvement in structural function. So, the aim of present study is to develop a unified model for morphological studies to explain the structural-morphologic components. Using a method called ad hoc scrutiny and diagrams analysis, the author has found three main structural-morphologic components (streets pattern, blocs pattern and zone pattern). In this regard, the technique of Urban Network Analysis (UNA) and the test of t-pair samples were chosen as the main tool. For this, Gheytarieh in Tehran was chosen as the study zone. It has planned, organic and semi-organic texture. The centrality indices which include accessibility, intermediacy, proximity, attraction and straightforwardness were evaluated in terms bloc, zone (area, shape, location), and roads network (the length and width of the route). It is worth to note that there was a huge building bloc in Gheytarieh (Sobhan Housing Complex) which distracted the whole location, since it obstructs the inter-textural accesses. Thus, in order to measure the effect of the morphological changes, the body modification was performed. The test of t-pair samples was carried out to measure the level of modification effects. The test results show that desired modifications in the form will lead to improvement in zone performance.
