Abstract: Public Transport-Oriented Development (TOD) is a planning model that effectively combine transportation function with land use. In view of the deficiency of considering guiding factors in the existing research on the relationship between rail transit stations and surrounding land use, this study improves the traditional "Node- place" model and increases an "accessibility" dimension in the model to reflect the node- place relationships. A TOD development measurement model is thus proposed in consideration of the spatial coupling function connectivity. Taking Shenzhen city as an example, the paper evaluates the TOD development level of the influence area at rail stations and reveals the synergistic relationship between rail transit and urban space. The result shows that the improved "Node- place" model performs better on identifying the "balanced site" than traditional models. The TOD comprehensive index decreases spatially from the core areas of Futian and Luohu District to the peripheral areas of Guangming, Longhua, and Longgang District. The Metro Line 2 and Metro Line 7 have a high level of node and place indexes. The Metro Line 6 and Metro Line 11 have high value agglomeration of the accessibility indexes. Most of rail stations in Luohu District have low accessibility, which shows the "Transit integrated development" or "Transit adjacent development". In addition, the higher the TOD comprehensive development level in the rail station influence area, the heavier the passenger flow at the stations, and the higher degree of the coordination between the two factors.
