A Policy Decision Process for Construction of Public Transportation City Model: Case Study of Jeju, Korea

The most suitable public transportation policies are planned and executed within the context of a long-term strategy due to their large time and money costs. Therefore, a public transportation city model should be developed after an adequate evaluation process to maximize social benefit and efficiency. The monetary evaluation methods that have been usually used to evaluate many alternative policies have some limitations in reflecting various factors, especially considering qualitative variables that are related to decision-making problems. On the contrary, the AHP (analytic hierarchy process) is a flexible model that deals with the qualitative variables and allows us to make decisions by personal judgment in a logical way. This paper includes implementation of the process to the construction of a ´JEJU´ public transportation city model to verify the applicability of the AHP method. Since this method includes a multi-criteria analysis process and reflects expert opinions, it is therefore very useful for finding a more broadly acceptable solution for goal-oriented policy making.
