Urban transportation selection based on universal design principles: An application with fuzzy vikor method

Universal design takes the approach to design that includes spaces, elements, and products that, to the greatest extent possible. It benefits users of all ages and abilities without the need for adaptation or specialized design. Although a set of acknowledged principles has been developed it is difficult to quantitatively evaluate whether a product is indeed a good example of UD. This study proposes fuzzy VIKOR method for evaluation of universal design. Problem of public transportation selection is handled by using fuzzy VIKOR. Criteria of problem are also principles of UD. The fuzzy VIKOR method has been developed to solve fuzzy multi-criteria problem with conflicting and noncommensurable criteria. This method solves problem in a fuzzy environment where both criteria and weights could be fuzzy sets. An empirical study is conducted to illustrate the practicability of the proposed approach.
