The invention discloses a road congestion prediction method, relates to the technical field of urban road traffic, and solves the technical problem of low accuracy of road congestion prediction in the prior art. According to the invention, a target road is divided into a plurality of road units based on intersection positions; obtaining road basic information and historical vehicle passing information of each road unit; calculating a road congestion coefficient of the target road based on the road basic information and the historical vehicle traffic data; obtaining a road congestion coefficient prediction value of the target road in the prediction period; and comparing the predicted value of the road congestion coefficient with a preset threshold value of a road congestion range to obtain the congestion degree. According to the method, the road congestion coefficient of each road unit is calculated by performing formulation processing on the congestion point density, the traffic light period and the historical vehicle passing data, so that the influence of the road congestion coefficient on the congestion degree of the road unit can be accurately reflected in a multi-dimensional manner, and the accuracy of predicting the road congestion can be improved.
