The most key areas of transportation networks are the intersections that form the intersection points of the roads. The location of the intersections and the roads that they connect to are one of the most important factors affecting the traffic flow. In this study, the importance of the intersection points on the streets and boulevards in the downtown of Malatya province in the transportation system will be determined. Population information has been calculated according to the city's land use plan. Intersection serving more than 90 percent of the population have been selected. Graph modeling made for Malatya downtown consists of 151 intersection points and 258 roads connecting these intersection points. The actual distance lengths of the roads are included in the graph modeling in meters. pagerank, eigenvector, closeness and betweenness centrality algorithms were applied on the weighted graph created. The properties and results of each algorithm are examined in detail. A homogeneous combining approach that contains all the unique features of these 4 algorithms has been applied and successful results have been obtained. The centrality values of the intersection points and the most effective intersection point are shown on the graph according to the results of all algorithms. R programming language was used for all analysis and visual operations.
