Analysis of the Relationship between Beijing Rail Transit and Urban Planning Based on Space Syntax

Transportation infrastructure planning is one of the essential ways to achieve a carbon-neutral society in China's future. With regards to sustainable urban development, the Green Low-Carbon policy for Transportation is set out in the 14th Five-Year Plan Outline 2021-2025. However, there are only a limited number of previous studies that systematically combined land-use planning and urban transportation evolution to clarify the structural issues in urban transportation optimization. In this study, we use traditional analysis and space syntax analysis to examine the relationship between the urban development of Beijing and the evolution of its rail transit transportation. After analyzing Beijing's multi-center and multi-circle rail transit structure, it was concluded that the current division of labor in Beijing's rail transit is unclear. Analysis using space syntax shows that connecting suburban centers using suburban railways improves accessibility better than subways. However, after analyzing the synergy between these factors, it is found that the application of space syntax needs to be analyzed in combination with the actual situation.
