To address low passenger flow efficiency in mega-cities' urban rail transit networks, this study takes Wuhan as a case, develops a multi-level framework to explore flow formation mechanisms, and proposes refined enhancement and prediction strategies. By comparing passenger flow evolution across different stages of networked operation, the study reveals a pattern of diminishing marginal returns in passenger flow growth, analyzes spatiotemporal characteristics at multiple levels, and identifies formation rules via correlation analysis. Based on the findings, a tiered strategy of "tapping the potential of core areas, improving the quality of central areas, and cultivating passenger demand in peripheral areas" is proposed, along with an optimized forecasting system that integrates macro-level multi-scenario prediction, corridor identification, and full-cycle dynamic calibration. The proposed framework provides systematic technical support for alleviating insufficient passenger flow and resource mismatch, offering practical value for sustainable urban rail transit development.
