The embodiment of the present application discloses a traffic flow forecasting method, device, equipment and medium, wherein the method includes: obtaining the historical road condition information of the candidate road sections in the candidate road section set, and the historical road condition information of the target road section to be predicted; according to the above The historical road condition information of the target road section and the historical road condition information of the candidate road sections in the above-mentioned candidate road section set, determine the candidate road section having correlation with the above-mentioned target road section from the above-mentioned candidate road section set, as a reference road section; obtain the current road condition information of the above-mentioned reference road section and the current road condition information of the target road section, predicting the traffic flow of the target road section at the next moment according to the current traffic condition information of the reference road section and the current road condition information of the target road section. By adopting the embodiment of the present application, the accuracy of predicting the traffic flow of a road section can be improved.
Description
technical field [0001] The present application relates to the field of intelligent driving, and in particular to a traffic flow prediction method, device, equipment and medium. Background technique [0002] With the increase of the number of urban vehicles, the problem of road traffic congestion is becoming more and more serious. Road traffic congestion will lead to low vehicle driving efficiency, insufficient utilization of road resources, and even cause traffic safety problems in severe cases. [0003] An important factor to avoid road traffic congestion is to determine the traffic flow of the road at the current moment, so as to predict the traffic flow at the next moment, and determine the driving route according to the traffic flow of each road at the next moment. How to improve the accuracy of forecasting road traffic flow, thereby reducing the road traffic congestion rate has become an urgent problem to be solved. Contents of the invention [0004] The embodiments ...
