The invention discloses a highway dynamic information publishing method based on risk propagation prediction, and relates to the technical field of traffic information publishing. Comprising the steps of actively identifying risk types, constructing a risk propagation database and a traffic risk influence range prediction model, predicting a risk influence range caused by a real-time risk event of a road section, and constructing an accident early warning grade prediction model based on a GBDT (Gradient Broken Decision Tree) to predict an accident early warning grade. And issuing traffic risk induction information in real time and the like. According to the method, information release and information early warning are performed in a targeted manner according to the real-time position of the vehicle and the variable information board, information release under the time granularity is switched along with time migration, accurate prediction and timely release of highway traffic risks are realized, the timeliness and reliability of information release are improved, and the traffic risk of the highway is prevented from being damaged. And the driving safety and the risk management and control capability are improved.
