Street geometric network case study centre of Khartoum (Sudan)

The main objective of this paper is to use the powerful Geographic information system and remote sensing to generate a geometric network for street in Khartoum center, for the purpose of management of the street network with in transportation system of the city. The data used in this paper was satellite image from Google earth and digital map from Ministry of Infrastructure, Department of Roads and Bridges. The present research comes to the conclusions that the Powerful geometric network has been designed and manipulated for the study area, within the GIS environmental and the geo-database with dataset and feature classes have been created to represent the reality of the geographic features in the study area. The application of the street geometric network has been subjected to different cases to evaluate their potentiality for meeting the essential requirements. The model shows great flexibility and powerful management facilities in production solutions for the real world problems concerning the traffic flow direction and motion distribution, such as the best route and the closest facility. The developed model is dynamic, so it could be modified, updated and subjected to further query processes among the study area.
