Abstract

To capture the complex spatial-temporal dynamics and periodic patterns in traffic flow data, and reduce the cumulative error effects caused by unexpected road conditions, this paper proposed a traffic flow prediction model based on combining PGCN and MAGRU. Firstly, the spatial-temporal data fusion module constructed periodic graphs using the property of periodic similarity in traffic flow data, and added spatial and temporal encoding information into the sequence data. Then, in the spatial-temporal feature extraction module, graph convolutional network(GCN) submodule captured spatial features from the periodic feature graphs, MAGRU submodule captured temporal features from the sequence data. Finally, the gated fusion mechanism fused the features extracted by both modules. It conducted the experiment on two real traffic flow datasets. The indicate that compared to several recent baseline models, the model achieves average reduction of 5.4%, 22.8%, 10.3% in MAE, RMSE and MAPE, exhibits an average improvement of 11.6% in R2 accuracy metric, which confirms that the model can provide more accurate predictions and reduce cumulative error effects.
