Integrated Land Use-oriented Design Practice for Rail Transit Complexes: The Yuhuazhai TOD Project (Hyper Park)

Against the dual backdrop of stringent land resource constraints and low-carbon urban development, Transit-Oriented Development (TOD) has emerged as a core pathway for spatial restructuring and sustainable growth in high-density cities. This paper takes the Yuhuazhai Depot Overbuild Development Project along Xi'an Metro Line 3 - the Yuhuazhai TOD project (Hyper Park) - as a case study of community-scale TOD practice. It elaborates on how the project, under the guidance of three-dimensional integrated land utilization principles, realizes the integration of "Station-City-People-Ecology" through structural engineering innovation, spatial organization optimization, and integrated ecological technologies. The project addresses key challenges in metro overbuild developments, including functional integration, spatial connection, vibration isolation, and ecological construction, through specific design approaches. The outcome is a 24-hour vibrant community integrating living, working, shopping, entertainment, mobility, and recreation, which enhances land-use efficiency, promotes jobs-housing balance, and strengthens ecological and health attributes. This paper presents relevant technical frameworks and design strategies for similar TOD developments in high-density urban contexts.
