Transportation Network Design using GIS Applications

Abstract

This research presents a transportation network analysis and design by using the capabilities of a Geographic Information System (GIS). Advancing the GIS basic technologies, we are using the network analyst in Arc GISto find out the best network schema, which fulfills the requirements of the Khartoum Metro Network and the services area. The need of a Metro system in a city is generally considered necessary when population of the city exceeds one million. Khartoum State crossed this milestone in the early 1990”s (2.44) Millions and has now around 8 millions. In this study we deal with a map and all the processes using Arc GIS V10.2 & QGIS V2.14.1 software to get the final results and a geo-database for the study area (Khartoum state), which contains road network, the suggested Metro network schema with its stations and paths as well as producing a number of thematic maps like the metro services area, accessibility, closest facility and shortest path for Metro Stations.The study recommends that by using a geo-database in Khartoum State will support decision-making processes reducing the risks of taking the wrong decisions based on incomplete information. This research contains an Overview, Theoretical Framework, Research Community, and the Methodologies implemented. These are followed by System Requirements, System Analysis and Design which produce the final results with some discussions and recommendations.
