Yogyakarta is one of the cities in Indonesia that has an agglomeration area by connecting 3 districts ring road. One of the biggest problems in the area is the intersection, particularly signalized intersections. The purpose of this study is to create a database, identify and map the road network at each intersection that can be used as a transport policy for the government. The research method is using ArcGis program by collecting various data on the Yogyakarta urban intersections that have been studied using the 1997 Indonesian Highway Capacity Manual method on the analysis of signal intersections. To produce a GIS map, map of Yogyakarta Administration and Google Earth Image maps are used as the main source. From the 20 intersections studied, the results showed that urban intersections, the road network tended to experience a poor level of service intersection (LOS F) with the percentage in 97%. The percentage of queue lengths tends to be as high as 62%, and percentage degree of saturation with a scope limit (LOS F) of 57%.
