## 4 Results of Qualitative and Quantitative (Morphological) Analysis  
### Morphological Regions  
#### 4.1.1 Characterization of Morphological Unit (Street Type and Street Age)  
This section is designated to address the characterization of the morphological unit (recognition and delimitation) of the selected heritage site. While discussions [41; 53; 54], regarding the selection of the urban morphological unit may vary, distinct regions can still be recognized. The choice of the unit, as conceptualized from the previous maps (a combination of the maps), causes the results of the process on the physical structure to differentiate one part of the urban area from another and exhibit patterns (types of forms) and configuration. \begin{table}

Table 1: Categories of character and metrics used for the element separation analysis. In the morphological concept and temporal perspective [55], the basic backbone of the morphology of cities [48] is shaped by the nature of the hierarchy of the street networks or the regular or less orderly sequences of the streets [56]. The evolution of streets is a tangible representation of time, offering glimpses about the specific periods in which it was built. For this purpose, to clarify the characterization of the morphological unit, the research focuses on two key variables: street age and street type. The methodology employed here aligns with [PERSON]'s evolutionary approach, emphasizing the principle of the historical stratification concept. This principle is central to systematically investigating for the proposed variables, associated with distinct morphological periods. It lays the groundwork for understanding how elements aggregate within the urban hierarchy over time. Street types do not occur typologically without geometry, so they tend to be defined systematically. The degree of resolution of street networks can vary not only between specific typological clusters but also within any typological cluster (containing clearly different or mutually exclusive types). This means that the urban street pattern as a whole is defined by the way the character formed by the types fits together collectively; conversely, types can be defined by how they relate to each other and as a whole. For this purpose, it is important to determine the route structures whose changes (properties of the types and the way they are connected to each other) play an important role in defining the character [42]. Figure 3 illustrates the manipulation of the different ages of the street layers within the current map of the Khan aggregate that led to the identification of five types of streets within each period. This analysis, conducted through Geographic Information Systems (GISs), involves overlaying drawn routes from each map to visualize the presence or absence of each street type in the current street structure. A few unchanged streets detected from the map of 1857 tend to show they do not respond to development as they outline the medieval street layout, which is often linked through loops, end loops, and cul-de-sac streets within the marketplace aggregation.
