Review of public transportation integration and modeling strategies: Toward seamless urban mobility

To solve the issues of expanding urbanization, traffic congestion, and environmental sustainability, public transportation system integration has become a crucial area of concern for urban planners and legislators. This paper discusses the concept of integrating different modes of transportation and the necessity of using a reliable modeling strategy to enhance and optimize urban mobility networks generally. The implementation and efficiency of integrated public transportation systems in several cities are examined in this research paper. The study focuses on a number of notable case studies of various cities that have made substantial efforts to integrate multiple modes of transportation to enhance urban mobility. This study provides a thorough overview of the advantages, difficulties, and potential solutions associated with integrated public transportation as it exists today and as it is currently being modeled. The research also examines several modeling strategies for integrated transport system design and optimization. This study seeks to provide significant insights into the current status of integrated public transportation, identify research gaps, and propose viable pathways for future research and development by synthesizing literature and case studies. Information for the analysis was gathered from the Web of Science, Scopus, Science direct, MDPI Publisher database spanning the years 2000 to 2024. The article collected a total of 624 bibliometric records of publications. Both quantitative and qualitative analyses were conducted as part of the study. This paper conducts a literature review focusing on the latest research concerning the Integration of public transportation-related subjects. It employs scientific databases, a specified list of keywords, and established inclusion criteria to gather data, assess content, and conduct a bibliometric analysis.
