The invention discloses a traffic flow prediction method, device, computer equipment and storage medium. The method includes: obtaining the transition probability matrix of each adjacent sub-road at the current moment according to the traffic flow data of each adjacent sub-road in the current road intersection; obtaining the corresponding transition probability matrix of each adjacent sub-road at the current moment The intersection probability matrix at the current moment; receive the intersection to be predicted, and obtain the corresponding adjacent road as the target road set; calculate the intersection corresponding to the intersection to be predicted according to the transition probability matrix at the current moment corresponding to each road in the target road set Predicting traffic flow data; according to the transition probability matrix of the adjacent road corresponding to the intersection to be predicted, and the traffic flow of the adjacent road corresponding to the intersection to be predicted, the predicted traffic flow data at the next moment corresponding to the intersection to be predicted is obtained. This method can obtain the transfer situation between each line through the line transfer matrix, and can make line planning and prediction in advance.
Description
technical field [0001] The present invention relates to the technical field of data analysis, and in particular, to a traffic flow prediction method, device, computer equipment and storage medium. Background technique [0002] At present, when measuring the traffic flow at each intersection on the road, it is mainly evaluated by the time and quantity of the road segments. relationship, resulting in inaccurate prediction of traffic flow. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention provide a traffic flow prediction method, device, computer equipment and storage medium, which aim to solve the problem that in the prior art, when measuring the traffic flow at each intersection on the road, it is mainly evaluated by the time and quantity of the road section. The connectivity between road segments is not considered, resulting in inaccurate predictions of traffic flow. [0004] In a first aspect, an embodiment of the present invention provides a tr...
