A Geographical Information System (GIS) utility, such as network analysis is a tool used to solve common network problem, This study is intended to use GIS as a tool of analyzing. integrating and displaying information. the overall activities of the work were concentrated around sub area selected as the study site in the Khartoum north city (Khartoum ) of main capital, Sudan .To demonstrate the use of road network analysis, this project focused on determining the best route between too destinations , the closest facility from a given incident , and a service area for a given facility . The present study attempt to analyze the potential use of network analysis in defining the optimal service area of different services such as hospitals, schools and university of Khartoum north. Generally for the purposes of this project ,distance is taken as impedance in order to find the best route and the closest facility and that of travel time is taken as impedance in order to find the service area.
