Abstract

This paper evaluates three alternative rail transit network proposals for Istanbul using a multiple criteria decision support system called Analytic Hierarchy Process (AHP). AHP facilitates decision making by organizing perceptions, experiences, knowledge and judgments into a hierarchical framework with a goal, scenarios, criteria and alternatives of choice. Based on this analysis, the decision makers have developed a new alternative as a combination of the most closely competing two alternative rail transit networks. The AHP was found to contribute effectively to solving complex problems. The sensitivity analysis method of the AHP, by displaying different outcomes depending on the priority given to high-level criteria, was found to be particularly important in the decision process.
