Abstract
The present study is focusing on development the accessibility of (Baghdad- Basrah) highway through choosing a new route for segment near Omarah city center, in addition to improve the level of service of city center network through removing the (Baghdad-Basrah) traffic from the center. To select the optimum route the Geographical Information System (GIS) with Multi Criteria Analysis (MCA) is used. The segment mentioned above is choosed due to the data availability required as an input for program, represented by control points coordinates, land use, and the existing ground elevation [Digital Elevation Model (DEM)].
As a result of this study the based model to suggest optimum route serving transportation movement and reducing congestion in AL-Omarah city is produced according to required criteria. So the obtained route is started and ended on the origin point of an approximate coordinate of (E695932, N3530317) and the destination point of an approximate coordinate of (E702400, N 3519760) receptively, with about 13 Km length. The main Importance of new route is not passing through city center which reduce the congestion, raising the level of service of center network, reducing the pavement deterioration due to remove the
heavy vehicle from passing though the center and finally the new route is shorter than the existing one which in turn reduce the travel time, cost, pollution and noise.
