Establishing the Index System for Sustainable Urban Transport Project Selection: an Application of Group MCDM based on the Fuzzy AHP Approach

The selection of urban transport projects can be viewed as a multiple criteria decision making problem (MCDM). This type of project typically has to achieve multiple targets such as economic, social, and environmental targets simultaneously; and it plays an important part in the future of the ecosystem in urban areas, and the country as a whole. The aim of this study is to propose a method for the sustainable urban transport selection problem. This method is based on two groups of criteria, namely, the expected impact of a project and the main barriers in the implementation of a project. After structuring the hierarchy, the fuzzy AHP is applied to determine the relative weights of the evaluation criteria. The results show that safety is the most important criterion of the future expected impacts and, at the same time, having support from relevant agencies is the most difficult job in the implementation. It is expected that the proposed method may serve as a reference for selecting urban transport projects.
