Short-term traffic flow data prediction method and system, computer equipment and storage medium

The invention belongs to the technical field of traffic control, and discloses a short-time traffic flow data prediction method and system, computer equipment and a storage medium, and the method comprises the steps: obtaining historical traffic flow data of a to-be-predicted region and all related regions of the to-be-predicted region; according to the historical traffic flow data of the to-be-predicted region, periodic traffic flow data of the to-be-predicted region in the current time period is obtained, and optimal related historical traffic flow data of the to-be-predicted region is obtained through a preset spatial-temporal feature selection method in combination with historical traffic flow data of each related region of the to-be-predicted region; acquiring external feature influence factor data of the current time period of the to-be-predicted area, and inputting the external feature influence factor data of the current time period of the to-be-predicted area, the periodic traffic flow data of the cu
