We deal with the improvement of public transportation service as for its enormous influence on the lives of residents and government spending. From the policymakers’ point of view the primary goal is to assess the level of public transportation and pinpoint practical ways to improve it in order to increase passenger satisfaction and draw in new customers. Two well-known multi-criteria decision-making techniques, the Fuzzy Analytical Hierarchy Process (FAHP) and the Fuzzy Technique for Order Performance by Similarity to Ideal Solution (FTOPSIS), were used through a dynamic questionnaire survey to accomplish this goal. The robust FAHP technique provides a systematic evaluation framework by taking feedback and interrelationships between different criteria levels. However, to obtain a thorough grasp of experts’ opinions about the quality of public transportation services, both approaches had to be used. A real-world situation for the city of Larissa, Thessaly was used in empirical research to show how these ideas can be applied in practice. The usefulness of these decision-making techniques is demonstrated by this study, which also emphasizes how crucial it is to prioritize public transportation system improvements in order to improve citizen lives.
