Integrating technological and strategic analysis: Evaluating the key determinants of transportation sustainability in taipei Mass Rapid Transit using the Rough-Fermatean DEMATEL approach

Mass Rapid Transit (MRT) systems are essential in densely populated cities, providing efficient, reliable transportation that alleviates congestion, reduces pollution, and promotes sustainable development. By accommodating large passenger volumes, MRTs enhance urban mobility, economic vitality, and quality of life, making them a vital component of modern urban infrastructure. Identifying key economic, social, environmental, and institutional determinants is crucial for advancing sustainable transportation systems. Integrating technological and strategic perspectives, this paper employs the innovative Rough-Fermatean Fuzzy Decision-Making Trial and Evaluation Laboratory (RFF-DEMATEL) approach to delve into the critical determinants of transportation sustainability in the Taipei Mass Rapid Transit (TMRT). The study acknowledges the interconnections among these factors, leading to a more genuine and precise evaluation, distinct from conventional methods that presuppose factor independence. Research outcomes indicate that “operations and performance” stand out as the paramount factors, underscoring the importance of operational strategies and economic allocation. “Digital technology economy” and “sustainable supply chain management” are also emphasized, pinpointing the necessity to harmonize public welfare with financial sustainability while cultivating enduring partnerships. The proposed approach's thorough categorization offers specific managerial suggestions, assisting TMRT in realizing its sustainability aspirations and aligning with the Sustainable Development Goals (SDGs). This investigation accentuates the significance of recognizing factor interdependence and adeptly managing uncertainties, bolstering the research's credibility and applicative worth.
