Therefore, this study aims to provide a practical framework for the selection decisions of final measures and policies to be carried out to achieve SUMP workspace goals using a fuzzy multi-criteria decision- making (MCDM) methodology. Alternatives are created with the strategic “pillar”, which was first adopted by the Podgorica city council. With the measurements in this pillar, the main criteria and the recommended measures for these measures create sub-criteria. Secondly, a Fuzzy Full Consistency Method (F-FUCOM) was used to determine the weights of the main and sub-criteria. The Fuzzy Combined Compromise Solution (F-CoCoSo) method was then applied to rank the alternatives. “The implementation and assurance of the SUMP” and “establishing a system for regular data collection, monitoring and evaluation of selected mobility indicators” were decided as the most important main and sub-criteria with weights of 0.286 and 0.1079, respectively. The findings suggest that the comprehensive planning for sustainable urban mobility alternative is first and the valorization of cycling potential alternative is second. A comprehensive sensitivity analysis confirms the validity, robustness, and effectiveness of the proposed framework. The applied methodology has the potential to assist decision makers in the process of developing SUMPs. Keywords: sustainable urban mobility plan; MCDM; fuzzy method; FUCOM; CoCoSo 1. Introduction In the past several decades, the tendency of rapid and unplanned urbanization and human population growth has been identified in all parts of the world. According to the United Nations statistics, more than one-half of the people worldwide reside in urban cen- ters, with expectations of further growth in the future [1]. The disparity between the travel needs and transport infrastructure resulted in a large number of adverse consequences, such as traffic congestion, road accidents, air and noise pollution, inefficient energy con- sumption, and finally and above all, the impacts on the general living standards of the people [2–4]. Therefore, new strategic transport planning and a design of the cities are essential to achieve sustainable development goals. By the beginning of the 1980s, the traditional approach to transport planning in many urban communities was characterized by the strong dependence on private cars as the primary travel option, insufficient encouragement of human-powered transport, and the inadequate coordination of transport and urban planning [5]. However, environmental, so- cial, and economic challenges led to a rapid paradigm shift in urban planning practice and the development of a novel approach that is nowadays widely recognized as sustainable urban mobility. The United Nations General Assembly has recently adopted a concluding document known as the 2030 Agenda for Sustainable Development which recognized Sustainability 2022, 14, 4972. https://doi.org/10.3390/su14094972 https://www.mdpi.com/journal/sustainability
