| The conflicts arising from the imbalance between rail transit supply and residents' mobility needs have resulted in congestion issues. The development potential of transportation nodes can be unleashed through optimizing spatial resource allocation through urban regeneration. Drawing from a comprehensive literature review, this study analyzes the distribution and changes of congested sites, categorizing cases into five distinct types to identify corresponding spatial challenges. Subsequently, using case studies from Xinzhuang, Lianhua Road, and Baoshan Road, this research delineates three primary spatial regeneration strategies: through adjusting the use of land, transferring the upper space and land development rights, adopting a three-dimensional urban layout, the regional space can be reconfigured; through expanding waiting space with public spaces in surrounding buildings, extending pedestrian overpasses to increase evacuation routes, and utilizing bus stops to connect with outbound pedestrian flow, the surrounding area can be unified; through widening platforms, integrating paid area flow lines, and upgrading building escalators, the internal environment can be improved. |
