The invention provides a traffic prediction method of a road network, computer equipment, a storage medium and a program product. The traffic prediction method of the road network comprises the following steps: constructing an undirected graph according to historical traffic flow data of the road network; processing the undirected graph through a graph convolutional network, and extracting spatial features of the historical traffic flow data; processing the traffic flow data with the spatial characteristics through a gating circulation unit, and extracting time characteristics of the historical traffic flow data; and obtaining a prediction result according to the spatial features and the time features. The traffic prediction method of the road network provided by the invention can improve the prediction precision.
