Yogyakarta's aglomeration intersection experienced congestion caused by the length of creating delay and queue length. The purpose of this research is to create a database, identify and map the road network at each intersection that becomes the research area using ArcGis program. The research method in this study is using the ArcGis by collecting various Yogyakarta intersection data then evaluating using the ArcGis program. To produce a map of Gis, a map of the DIY Administration and maps of the Google Earth image are used as the main source. The results showed that the urban intersection after the mapping of the road network tended to experience poor service levels (F), the percentage of intersections that experinced poor service levels was 97%, the percentage of queue lengths tended to be as high as 62%, and the percentage of the degree of saturation with a limit of scipe (F) was 57%. Thus causing various congestion problems in Yogyakarta. The results of this study provide information in the form of road network maps to determine congestion points at various intersections.
