The invention relates to a traffic flow prediction model based on a gated time convolutional network. According to the traffic flow combined prediction model, a G-TCN models time dependence, spatial correlation and a long-time sequence of traffic flow respectively. A time convolution network (TCN) and a graph convolution network (GCN) are used for capturing time dependence and spatial correlation of traffic flow respectively, and an STA-Block module models the spatial-temporal correlation of a long-time sequence through a spatial-temporal attention mechanism and a gating fusion mechanism. A self-adaptive adjacent matrix is constructed in a G-TCN model, and learning is performed through node embedding. The model can accurately capture the hidden space-time dependency relationship in the traffic flow data.
