The effect of Spatial Configuration on the Sociability of Informal Settlements: (Case study of Hesar and Dizaj Neighborhoods in Hamedan)

In recent years, for reasons such as population growth, increased rural migration, and the migrants’ financial inability to afford housing, the host cities are facing the problem of illegal settlements that are built densely without observing the principles of construction. These are usually known as informal settlements which face many problems. One of the problems is the lack of social spaces that could act as the pillar of urban life. The issue of socialization and social interactions has been neglected in marginal and informal urban contexts, but it is more important that than in other contexts. It is because these contexts are in fact one of the most prominent manifestations of urban poverty in most Iranian cities with migration inflow. The promotion of socialization in these informal settlements, which are a part of the city’s body, is one of the main goals for increasing public welfare and citizens’ peace through the provision of their social needs. In recent years, hybrid studies have considered the relationship between cognitive maps and spatial configuration in assessing the shape of the constructed environment, but few studies have focused on adapting the findings of space layout approach by comparing cognitive maps when studying and measuring social behaviors of citizens in one of the most problematic urban contexts, i.e. informal settlements. This is an innovation in this research, an applied area and a step forward in the field of urban psychology, which can help urban planners and decision makers to identify and improve the morphology of more sociable urban neighborhoods. The present study seeks to investigate the effect of the physical-spatial characteristics of these settlements on sociability by examining the neighborhoods of Hesar and Dizaj in Hamedan. In the first step, the related literature and theoretical concepts were reviewed by library research and consulting with valuable sources on spatial configuration, socialization, and informal settlements. In the second step, the maps of the two neighborhoods were simulated in the Space Syntax software and analyzed formally and morphologically as follows. In the analysis of research data, in line with the natural motion theory, the role of spatial configuration was examined in the formation of behavioral and social patterns (in particular, socialization behavior). In fact, this applied study is based on a mixed methodology. In the first step, quantitative techniques were used along with the theory of natural motion, the theory of space syntax, as well as Arc GIS and UCL Depth Map software packages to analyze spatial configuration and its role in the social behavior of citizens with the aim of specifying the physical-spatial factors which influence sociability in urban spaces. The next step aimed at determining the validity and reliability of the results. In this step, the quantitative results were reconsidered by means of the qualitative method of cognitive maps. According to the findings, spatial configuration may affect the sociability of informal settlements through five indicators, namely, control, connectivity, integration, depth, and legibility. It may also affect people’s attendance, motion, face-to-face contact, and conversations (which are the major prerequisites of the formation of social interactions). Our analysis of the abovementioned informal settlements shows that the maps of the quantitative method of space syntax almost overlap with the qualitative cognitive maps. A comparison between the two neighborhoods indicates that the tree-like and continuous space configuration of Dizaj creates a motion pattern that leads to social interactions in the middle parts of the neighborhood whereas the shrub-like configuration in Hesar distributes the patterns of motion and social behavior all over the neighborhood and leads to more desirable social effects.
