Highway route selection using GIS and analytical hierarchy process case study Ramadi Heet rural highway

Abstract An appropriate road network imposes on planners take into account factors such as land use, slope, soil type, hydrology, and agricultural area. Due to various considerations desires, the planning process is difficult hence there may be confusion in interest decision-making process. The use of a geographic information system (GIS) Multi-Criteria Decision Analysis (MCDA) assist achieving more detailed desirable results. Thus, reducing complexity helping stakeholders for drawing general conclusion. study site was chosen an area between cities Ramadi Heet Anbar Province, western Iraq, where it suffers from congestion traffic accidents. This research aims integrate set evaluation criteria using Analytical Hierarchy Process (AHP) spatial multicriteria model find optimal path In this study, two alternate paths were proposed compared with current best path. Finally, results indicated that first alternative 36% better. succeeded proving possible decide rural highway route GIS MCDA.
