TY - JOUR PY - 2023// TI - Spatial-temporal hypergraph convolutional network for traffic forecasting JO - PeerJ Computer science A1 - Zhao, Zhenzhen A1 - Shen, Guojiang A1 - Zhou, Junjie A1 - Jin, Junchen A1 - Kong, Xiangjie SP - e1450 EP - e1450 VL - 9 IS - N2 - Accurate traffic forecasting plays a critical role in the construction of intelligent transportation systems. However, due to the across road-network isomorphism in the spatial dimension and the periodic drift in the temporal dimension, existing traffic forecasting methods cannot satisfy the intricate spatial-temporal characteristics well. In this article, a spatial-temporal hypergraph convolutional network for traffic forecasting (ST-HCN) is proposed to tackle the problems mentioned above. Specifically, the proposed framework applies the K-means clustering algorithm and the connection characteristics of the physical road network itself to unify the local correlation and across road-network isomorphism. Then, a dual-channel hypergraph convolution to capture high-order spatial relationships in traffic data is established. Furthermore, the proposed framework utilizes a long short-term memory network with a convolution module (ConvLSTM) to deal with the periodic drift problem. Finally, the experiments in the real world demonstrate that the proposed framework outperforms the state-of-the-art baselines.
