Integrating Intelligent Transportation Systems (ITS) to Enhance Accessibility and Efficiency of Public Transportation Networks in High-Density Urban Areas

Rapid urbanization and increasing travel demand in high-density urban areas have intensified pressure on public transportation systems, resulting in congestion, reduced accessibility, and declining operational efficiency. Intelligent Transportation Systems (ITS) have emerged as an effective approach for addressing these challenges by integrating advanced information, communication, and traffic management technologies into public transport networks. This study aims to examine the role of ITS in enhancing accessibility and improving the operational efficiency of public transportation in densely populated urban environments. Adopting a conceptual and analytical review approach, the study synthesizes recent literature and international experiences to identify the key ITS components, their functional mechanisms, and their contributions to sustainable urban mobility. The findings indicate that ITS applications—including real-time passenger information, adaptive traffic signal control, automated fare collection, fleet management systems, and integrated mobility platforms—significantly improve service reliability, reduce travel time, optimize network performance, and increase user satisfaction. Furthermore, the integration of these technologies strengthens equitable access to public transport while supporting environmental sustainability and smart city development. The study concludes that successful ITS implementation requires integrated planning, supportive institutional frameworks, and continuous technological investment to maximize the performance and resilience of urban public transportation systems.
