Abstract

The analysis of urban street centrality indices can be used for decision-making in transportation and traffic management in metropolitan cities. Centrality measurement is often used in urban network analysis related to urban development. In this paper, in the first step, centrality indices with a wide range of applications in the performance of the street network were examined, and two important known indices were used. Then, using the centrality toolbar in the geographic information system (GIS) environment, the necessary analysis was performed in the urban network of the studied area. The population of adjacent buildings was determined as the weight affecting the network elements (nodes and arcs). The results of the study were compared for the street network, medical centers, and at the scale of the district. The final result made it possible to identify a dense street network, main roads with high demand, and medical centers with more centrality. Also, the degree of correlation of these indices with each other and in relation to each district was determined. On the other hand, the possibility of clustering the entire districts was provided.
