In view of the limitations of the two-dimensional perspective of the traditional node-place model in complex urban environments, this study constructs a three-dimensional "node-place-vitality" model. With 41 stations of Jinan's rail transit as the research subjects, a service radius of 800 meters around each station is demarcated. Twenty-four indicators are selected from three dimensions: traffic function (node), urban space (place), and dynamic vitality (vitality). The comprehensive subjective-objective weighting method and K-means clustering analysis are employed to evaluate the coordination of station areas. The results indicate that the three-dimensional model can effectively uncover the synergistic relationships among nodes, places, and vitality. Moreover, the stations are classified into five types: high-vitality hub stations, vitality-improvement stations, balanced-development stations, node-reinforcement stations, and comprehensive-cultivation stations. Their spatial distribution is highly associated with the development characteristics of Jinan's main urban centers, sub-centers, and marginal areas. This research offers a scientific foundation for the optimization of Jinan's rail transit station areas and the formulation of TOD strategies. Additionally, it provides a novel perspective for studies on the coordination of station areas in similar cities.
