Abstract
Coordinating urban rail transit (URT) systems with surrounding land development is essential for sustainable metropolitan growth, yet the mechanisms linking passenger flow intensity and development density remain insufficiently understood. This study develops a multi-city analytical framework that couples complex network models (Space-L and Space-P) with a passenger flow intensity–land development density optimization model based on a distribution estimation algorithm. Using Chengdu and Shenzhen as contrasting Chinese megacities at different development stages, we quantify network topology, station-area floor area ratios and passenger flow intensities within an 800 m radius of URT stations. Results show that Shenzhen's mature, high-density grid network achieves a higher coordination degree between passenger flow and development density (0.85) than Chengdu's evolving monocentric–polycentric system (0.72). Shenzhen also exhibits higher average floor area ratios (4.2 vs. 2.8) and passenger flow intensities (45,000–68,000 vs. 25,000–40,000 passengers/km·day). The proposed optimization algorithm improves convergence performance by 12–15% relative to traditional methods. The findings reveal two distinct coordination typologies, an adaptive evolutionary model and a mature intensive-development model, and provide a replicable framework for diagnosing and improving URT–land use coupling in cities at different development stages.
