The embodiments of the present invention disclose a road state prediction method and a device. The method comprises the steps of determining the state array of associated roads according to a to-be-predicted road, wherein the matrix value of the state array of associated roads is just the status value of roads that meet a preset distance relationship with the to-be-predicted road at a preset historical moment; calculating the to-be-predicted state of the to-be-predicted road according to the probabilistic relation between the to-be-predicted state of the to-be-predicted road at a to-be-predicted moment and the state array of associated roads. According to the technical scheme of the embodiments of the present invention, the state of the to-be-predicted road is predicted based on the probabilistic relation between the to-be-predicted state of the to-be-predicted road at the to-be-predicted moment and the state array of roads associated with the to-be-predicted road. Therefore, the road prediction accuracy is improved.
