PERFORMANCE EVALUATION AND SELECTION OF BEST MODE OF TRANSPORTATION IN LAGOS STATE METROPOLIS

Abstract

This paper describes an application of the Saaty‘s Analytic Hierarchy Process (AHP) and fuzzy set for selecting the best mode of transportation in Lagos State metropolis. Seven transportation alternatives were considered: private car, okada, keke-napep, train, ferry, commercial bus and taxi. These alternative modes of transportation were evaluated with nine decision criteria: low transportation cost, low environmental effect, large capacity, improved safety, high comfort, high accessibility, improved reliability, low number of interchanges required and faster journey time. This method is used in such a way that information from commuters, who were asked to express their opinions in the ranking of decision criteria, was used in hierarchy prioritization of the criteria and expressed in fuzzy numbers with triangular membership functions. The method is applied at two levels: beginning with the finding of fuzzy weights for the decision criteria, followed by finding the fuzzy weights for the alternatives under each of the decision criteria. Fuzzy scores for the alternatives were obtained.
