| Summary | Railway grade separation projects for metropolitan areas of many countries have been highly focused for a long time. In past years, there has only been one evaluation criterion used, cost and benefit analysis. As such, we have been lacking a suitable mechanism for considering both the development of railway operations and urban re-development. Therefore, a win-win opportunity has not been achievable so far. The aim of this study is to establish the mechanism and evaluation criteria of railway grade separation projects using a rational and objective decision-making process. This will enable us to figure out the construction priority of railway grade separation projects under the constraint of limited resource, and also to use the profits from land development towards construction cost. This study adopts a forum and questionnaire of experts and uses the Fuzzy Analytic Hierarch Process (FAHP) to analyze the weighting of evaluation criteria. Furthermore, we utilize the VIKOR method in order to determine the construction priority of railway grade separation projects. The result shows the evaluation mechanism can be divided into four phases; application phase, feasibility study phase, comprehensive planning phase, and ratified project phase. The critical conditions, emphasis, and evaluation criteria in each phase are different. This research also uses actual projects as case studies in the feasibility study phase and comprehensive planning phase. The result shows that its prediction is very close to reality and we can propose improvement strategies for the relevant authorities. In order to execute the operation of railway grade separation projects more efficienctly and effectively, this study suggests that the relevant authority establishes an “evaluation committee of railway grade separation projects” and build “a development fund for railway grade separation projects.” It is hopeful that this study will be beneficial for the evaluation mechanism of the railway grade separation projects. |
