This study systematically reviews literature on the evaluation and enhancement of urban public transportation service quality from 2000 to 2023.Employing content analysis,it reveals the similarities and differences in domestic and inter-national literature,further synthesizing details through document analysis.The findings indicate divergent preferences in research themes and content characteristics globally,with passenger satis-faction emerging as a current focal point of interest.Government and corporate entities,along with the public,serve as the pri-mary perspectives for macro and micro-level research,respec-tively.The evaluation content concentrates on two major sys-tems:perceived service and objective performance,both exhibi-ting measurable interrelations.Multi-modal integration and spatial environment are prioritized directions for improving evalu-ation indices,with location-based services and satisfaction metrics serving as pivotal points of methodological intervention.Internal improvements and modal complementarity constitute the main strategies for enhancement,while Importance-Perform-ance Analysis and the Three-Factor Theory model represent ef-fective exploratory solutions to address challenges.Future re-search should focus on incorporating spatial environmental indi-ces,enriching evaluation methods with internet big data,and exploring service quality enhancement pathways based on spatial perspectives.
