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.
