Urban Integration Challenge: Xiamen Metro Line 1 was more than a transport infrastructure project; it represented a major urban regeneration catalyst for the broader metropolitan area. With 26 stations extending across different urban districts, each station precinct had distinct catchment characteristics, development constraints, land-use conditions, and market potential. The core challenge was to identify how selected station areas could be transformed into high-value TOD nodes while balancing commercial feasibility, public function, urban identity, and long-term city-building objectives. With this in mind, 10 key station precincts along the corridor were selected as priority nodes for comprehensive TOD study and planning.

• TOD Implementation: Yun recognized that TOD systems are not linear development models, but interconnected networks of station-level micro-markets. Each node required a differentiated strategy based on its surrounding cultural context, policy direction, demographic profile, economic base, land-use structure, and accessibility potential. Through holistic site research and station-specific development modeling, Yun helped identify the unique role and value proposition of each station precinct within the broader corridor. The proposed plans were tested repeatedly through Highest and Best Use analysis to ensure that development intensity was optimized in commercially viable locations while preserving the civic function, walkability, and public-realm quality essential to successful TOD.

• Station-Specific Development Strategy: Rather than applying a standardized land-use formula across the corridor, the study developed tailored positioning strategies for each priority node. High-density commercial and mixed-use programs were directed toward stations with stronger market depth and accessibility advantages, while civic, community, cultural, and leisure-oriented functions were integrated into nodes with stronger public-service or placemaking potential. This approach helped create a more balanced TOD network, where each station supported both localized demand and system-wide value creation.

• Financial Modeling and Land Value Capture: Yun built multi-variable financial models to assess land value capture potential, development phasing, asset mix, and investment feasibility for each node. The analysis evaluated the optimal balance among investment-grade commercial assets, residential components, social infrastructure, government facilities, and experiential leisure venues. Scenario-based socioeconomic simulations were used to test different phasing strategies, allowing the plan to respond to market absorption, infrastructure timing, public-sector priorities, and long-term urban growth patterns.

• Outcome: Xiamen Metro Line 1 was successfully launched in 2017 and became an important reference point for localized TOD planning in mainland China. The project demonstrated how metro infrastructure could be leveraged not only to improve mobility, but also to shape urban growth, unlock land value, and create integrated station-area communities. As one of the earlier comprehensive TOD studies of its kind outside Hong Kong, the project contributed to the development of a more localized TOD model for Chinese cities.
