Abstract
This study is intended to use GIS as a tool in analyzing, integrating
and displaying information. The over all activities of the work were
concentrated around sub area selected as the study site in the Arada
sub city (kifle ketema) of the main capital, Addis Ababa. To
demonstrate the use of road network analysis, this project focused on
determining the best route between two destinations, the closest
facility from a given incident, and a service area for a given facility.
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. A Geographical Information System (GIS) utility, which is
network analyst, determined the best route, the closest facility and the
service area. For this purpose database is created using SQL-SERVER.
Data used by this project included public data and data generated using
a Global Positioning System (GPS). Once analysis was completed, a
route representing the (the best route) shortest travel distance, the
route representing the closest facility and the polygons representing
the service area were developed.
