A Fuzzy-based Sustainability Assessment Approach for Promoting Sustainable Urban Mobility

Sustainable urban mobility refers to the broad subject of urban transport that is sustainable in the senses of economic, social, and environmental perspectives by meeting the needs of both current and future generations in an efficient manner. This paper presents a fuzzy-based sustainability assessment approach for the promotion of sustainable urban mobility. It can be used to assist decision makers in assessing mobility alternatives and enabling urban planners to make necessary adjustments of more sustainable urban mobility. In the proposed approach, a hierarchical structure of sustainability indicators was developed as decision criteria for the sustainability assessment. Fuzzy measures based on Gaussian fuzzy numbers associated with 7-point linguistic terms were used to aggregate the indicators into a performance index. A case study concerning the sustainability assessment of alternatives for urban transportation systems was conducted. A modified shared-use vehicle system was further proposed for supporting the implementation of the case study.
