This literature review examines the challenges of integrating the public transportation system in Palembang, including limited coverage, lack of intermodal connectivity, and suboptimal fare and information integration. The study aims to analyze the existing conditions, evaluate modal and operational integration, and design strategies for a more efficient, integrated, and sustainable transportation system. The research employs bibliometric analysis using VOSviewer, with data from Google Scholar, Scopus, ResearchGate, and Elsevier. Relevant articles are identified and analyzed through VOSviewer to map the relationships between articles, authors, and key research themes. The findings reveal research trends on integrated public transportation in Palembang, emphasizing policies, technology, and user experience. Research gaps are identified in modal integration, implementation approaches, and agglomeration connectivity. One underexplored aspect is the impact of policies on public transport integration, including regulations, incentives, and subsidies. This study highlights the importance of policy-based strategies, spatial planning, and technology to enhance public transport services. Additionally, a user-experience-driven approach is essential to developing a more integrated, efficient, and attractive public transportation system, encouraging a modal shift toward more sustainable mobility solutions.
