Track Selection for Light Rail Transit (LRT) Projects by Applying Analytic Hierarchy Process (AHP) Decision-Making Method — Case Study: Evaluation of Addis Ababa Light Rail Transit (AALRT) Project's Track Selection

Track selection for certain light rail transit (LRT) projects is difficult and complex in view of the many factors to be considered. Many track alternatives can be considered for a project, and very detailed cost and multi-factors analysis work is needed, which is time and budget consuming. This paper presents one demonstration of LTR track selection using a analytic hierarchy process (AHP) decision-making method from different track alternatives. As an example, the evaluation of appropriateness of the under-construction Addis Ababa Light Rail Transit (AALRT) track selection is presented. For the evaluation, five tracks clustered into three major alternatives: ballasted track, prefabricated slab/ floating ladder track, and green tracks, based on AHP guidelines and facts behind their similarities and features, are considered. After detailed analysis for AALRT track selection using basic AHP principles, green tracks is found to be the best choice. Depending on the output of the evaluation for the AALRT project (ballasted track) track selection, necessary suggestions are made for future extension and new construction of LRT projects in that city.
