A study of road network development prioritization at Lembata district - east nusa tenggara province, Indonesia

The objective of the study was to prepare a recommendation on how to set up a road network construction programming in Lembata District, Indonesia given such constraints as budget, types of construction, and so on. There were eight road segments across Lembata District included in the road network under consideration. To achieve the objective, the Analytic Hierarchy Process (AHP) method was applied.  The process was initiated by brainstorming factors that may affect the selection and prioritization, called in the AHP analysis criteria. The factors were then evaluated using the Cut Off method to select the most suitable ones. From the analysis it was found that factors strongly influence in the selection were road condition, type of road surface, accessibility, mobility, population density, land use disparity, poverty alleviation program, and construction cost.  Using the above criteria, an AHP analysis was then conducted to set up a prioritization recommendation for the road construction sequences. It was found that the construction cost was the most important factor to be considered, followed by land use disparity and road condition.
