| Abstract | ||
| Algerian cities in general, and the city of Djelfa in particular, are witnessing significant demographic growth and rapid spatial expansion, which has resulted in the emergence of new neighborhoods somewhat far from the historical city center, which is saturated with commercial and service activities. The research aims to identify whether visitors can meet residents outside the old city center, the level of interaction between them, and the most appealing areas for this interaction, which could develop into secondary commercial zones that alleviate pressure on the city center. We utilized the spatial syntax technique to measure these interactions by modeling the maps of the city of Djelfa into axial maps and measuring indicators such as global integration (Rn), local integration (R3 and R5), and synergy. The research confirmed the effectiveness of the adopted methodology, revealing a weak synergy index, i.e., weak interaction between visitors and locals at the city level. While the historic city center has maintained its centrality, it has expanded beyond its borders, and the Boutrifis district has emerged as a secondary local commercial hub. Some neighborhoods appear isolated according to the global integration index, but they witness significant internal movement based on local integration, such as the Al-Fusha, Al-Shawa, Bin Saeed, and Al-Zaria neighborhoods. | ||
