Supporting stations as third places in evolving rail transit systems: The case of Istanbul
As cities prioritize transit-oriented development (TOD) to reduce automobile dependence and promote sustainable urban growth, the role of rail stations is evolving from mere transportation nodes to vibrant social hubs. This research addresses the gap between the functional role of rail stations and their capacity to foster third places, using Istanbul as a case study. Employing the Node-Place-Third Place-Ridership-Time (NPTPRT) model, the study provides a multidimensional framework to evaluate the integration of rail stations with surrounding land uses, ridership trends with temporal dynamics, and social engagement. The research examines 29 stations across diverse urban and suburban settings to analyze the influence of station characteristics on ridership dynamics and community interactions. A comprehensive methodology was developed, incorporating field observations, geospatial analysis, and institutional data to measure the node, place, and third-place attributes of each station. The findings reveal that stations with high accessibility and integrated land-use characteristics not only attract greater ridership but also foster stronger community engagement, validating the hypothesis that TOD strategies enhance urban vitality when stations function as third places. Moreover, the study identifies stations where performance and ridership trends, influenced by temporal dynamics, deviate from the balance of integration, providing valuable insights for transit planning and station design. By incorporating the concept of third places into traditional TOD frameworks, this research highlights the potential for rail stations to act as centers of social life, extending their utility beyond transit. This study contributes to the TOD literature by demonstrating the dual role of rail transit stations as transportation nodes and community spaces. It underscores the importance of designing rail stations with a social dimension to create more sustainable and inclusive urban environments. While focused on Istanbul, the findings offer broader insights for cities worldwide navigating the challenges of rapid urbanization and expanding transit networks. By emphasizing the intersection of mobility and livability, this research presents actionable recommendations for enhancing urban vitality through integrated station planning and management.
