An Attention Encoder-Decoder Dual Graph Convolutional Network with Time Series Correlation for Multi-Step Traffic Flow Prediction

Shanchun Zhao, Xu Li, Yajie Zou
2022 Journal of Advanced Transportation  
In this paper, we propose an attentional encoder-decoder dual graph convolution model with time-series correlation (AED-DGCN-TSC) for solving the spatio-temporal sequence prediction problem in the traffic  ...  Then, the gated dual graph convolution recurrent unit uses the graph convolution operation, which combines the ideas of node embedding, and dual graph, as an operation inside the gated recurrent structure  ...  Guo et al. added the attention mechanism module to the spatio-temporal graph convolution to capture dynamic spatio-temporal features in traffic data [31] .  ...
