Paths Planning for AL-Ramdi intercity road using gis tool


Transportation planning process (find the best route) can be considered as astrategic, important and complex issue in the same time, due to the need of collectinginformation and analyzing data to obtain the optimum network (journey of shortestroute), ie.,minimizing time,coast, fuel, noise, and air pollution.(GIS), the network should be analysis to find the best route based on shortestdistance with minimum time between the origin and destination of journey by usingsoftware’s algorithm. Moreover, the ability of GIS to generate detailed directions alongthe route, providing as-you-need-it solutions for common problems.The algorithm divides the network into nodes (ie, start, and lines intersection) andthe paths between such nodes are represented by lines. In addition, each line has anassociated cost representing the cost (length or time) of each line in order to reach anode. There are many possible paths between the origin and destination, but the pathcalculated depends on which nodes are visited and in which order.A case study of Al-Ramadi city is choosed for this study, it lies in the west part ofAl-Iraq; it’s the capital of Al Anbar Governorate and is situated at the intersection ofthe Euphrates River and Al Warrar River’s Channel, northwest of Al-HabbaniyahLake. The city is 110 km west of Baghdad, 46 km west of Al-Fallujah, and 283 kmeast of Al-Rutbah. It lies on the major paths to Syrian and Jordanian boarders, so itoccupies a strategic planning concern.The objectives of this study is to find the shortest time (least cost path) betweenzones of Al-Ramadi city, for that the city of Al-Ramadi is divided into (5) TrafficAnalysis Zones (TAZ), the centered of each zone is obtained in order to compute theshortest time from the center of first zone (origin) to the center of second zone(destination).The result of this study is a matrix,It shows the least time to travel between the 5(TAZ), these results can be considered very important to implement IntelligentTransportation System (ITS).
