Abstract:

Flow of urban drainage networks are critical indicators of their operational efficiency and safety. Accurately forecasting these parameters is crucial for risk mitigation, performance enhancement, and layout planning of the networks. Traditional flow forecasting methods typically overlook the complex multidimensional spatial dependencies between the flows in pipelines. This paper proposes a multi-view spatio-temporal graph convolutional networks model that considers both the spatial proximity and attribute similarity of network nodes. It constructs the nearest neighbor-based graph and the flow similarity-based graph, utilizes spatio-temporal graph convolutional networks to uncover intrinsic dependencies, and applies an attention mechanism to merge features from multiple views for enhanced flow predictions. Experiments with historical flow data from an urban drainage network confirm the superior predictive capabilities of our model, with ablation studies validating the contributions of different views.
