2This study proposes an advanced Graph Convolutional Network (GCN) model to predict daily bicycle rental volumes at the station level, addressing imbalanced usage patterns in shared bicycle services. Bicycle stations are modeled as nodes and user interactions as edges, with spatial (e.g., location, infrastructure) and temporal (e.g., weather, time) features incorporated. Optimized through hyper-parameter tuning, the model surpasses traditional methods and GCN model without spatial features, effec
