The invention discloses a vehicle path dynamic adaptive planning method and system, computer equipment and a storage medium. The method comprises the following steps: step 1, establishing a road section flow dynamic loading model in an urban traffic network so as to predict the traffic flow; establishing a vehicle travel time prediction model considering the traffic state to predict future road section passing time; and step 2, solving a path planning problem which aims at minimizing the vehicle travel time under the dynamic traffic road condition based on an improved ant colony algorithm by using the vehicle travel time prediction model so as to obtain a path with the shortest vehicle travel time. According to the method disclosed by the invention, the road network traffic flow dynamic loading model is established from the aspects of the spatial correlation of the road section and the dynamic change of the traffic road condition by comprehensively analyzing the propagation of the traffic jam and the change of the road section traffic road condition and considering the influence of the jam propagation process on the traffic flow; accurate prediction of the vehicle travel time under a dynamic traffic situation is realized.
