The invention relates to the field of artificial intelligence, discloses a traffic jam prediction method, device and equipment and a storage medium. The method is used for solving the technical problem that a traffic jam condition cannot be predicted in an existing urban intelligent traffic system. The method comprises the following steps: according to a traffic jam prediction request, obtaining traffic flow data at each traffic gate to obtain a traffic flow data set; analyzing the parameters of the traffic checkpoints in the traffic flow data set by using a big data analysis technology to obtain node parameters; calculating the relationship among the traffic checkpoints to obtain edge parameters; and generating a traffic map in a preset time period based on the node parameters and the edge parameters through a pre-constructed road network knowledge graph, and inputting the traffic map into a traffic prediction model pre-established based on a graph convolutional neural network for road condition prediction processing to obtain a predicted value of the congestion degree of each traffic gate corresponding to the traffic congestion prediction request. In addition, the invention also relates to a block chain technology, and the related information of the traffic flow data can be stored in a block chain.
