Managing uncertainties in urban junction design: a case study of the FAHP method in Chettia

Abstract

The essay delves into how an urban crossroads in Chettia, Algeria was reconstructed using the Fuzzy Analytic Hierarchy Process (FAHP) method to assess and choose the best design from multiple alternatives. The inherent uncertainties in this type of project can be effectively managed by using fuzzy algorithms, which mimic human reasoning in decision-making. A comprehensive and organised study is made possible by the methodology's foundational premise on a hierarchical problem classification into 32 criteria and sub-criteria. To establish the weightings of these criteria and lay the groundwork for comparing alternatives, the FAHP approach is employed, which is well-known in the area of multi-criteria decision-making. The feasibility and efficacy of this method are illustrated in the case study pertaining to the reconstruction of the Chettia intersection. A global performance indicator was used to rate the four solutions that the experts reviewed. When it comes to building and maintaining rural road networks, this strategy is invaluable for making educated decisions. In this case, the FAHP method provides a rigorous and methodical way to choose the optimal design. It enables the management of the uncertainties inherent in this type of urban infrastructure project while considering various complicated and sometimes contradicting aspects. Urban planners and transportation engineers may benefit much from this concept if it were applied to other comparable projects.
