This paper provides an understanding of the quality of urban form by studying the spatial properties of street networks concerning human density in Baghdad, Iraq. By adopting the Multiple Centrality Assessment (MCA) as an analytical approach, the study examines 12 streets at two different urban patterns formed in Rusafa District. Among many key measures of MCA, betweenness centrality (C^B), which is a metric representation of street qualities, has been employed to identify streets with high values in the network system. Then, the human density based on people flow – denoted the quality of urban life – was measured by site observations which focused on movement and activity. Following that, a correlation between street centrality and human density for the two examined areas was conducted and compared. Results showed that urban life was found on organic streets, where vitality, activity, and density existed with high values of betweenness; this contrasted with modern streets, which recorded low values. Furthermore, research that explored the relationship between street network systems and urban form potential can involve other key MCA measures, including Closeness (C^C) and Straightness (C^S), when examining the walkability, sustainability, territory, and history.

本文通过研究与伊拉克巴格达有关人口密度的街道网络的空间特性，提供了对城市形态质量的理解。通过采用多重中心度评估（MCA）作为分析方法，该研究考察了Rusafa区形成的两种不同城市模式下的12条街道。在MCA的许多关键指标中，中介中心度（C ^B）它是街道质量的度量表示形式，已被用来识别网络系统中具有较高价值的街道。然后，通过以移动和活动为重点的现场观察来测量基于人员流动的人口密度（表示城市生活质量）。之后，对两个检查区域的街道中心性与人口密度之间的相关性进行了比较。结果表明，城市生活被发现在有机的街道上，那里的生命力，活动性和密度都很高，介于两者之间。这与记录了低价值的现代街道形成了鲜明对比。此外，探索街道网络系统与城市形态潜力之间关系的研究可能涉及其他关键的MCA措施，包括“亲密性（C ^C）和直线度（C ^S），当检查步行性，可持续性，地域和历史时。
