One or more embodiments of the invention provide a traffic flow prediction method and apparatus, a computing device and a medium. The method comprises the steps that the topological relation of all point locations in a set road section is obtained according to road network data, and the point locations are arranged on the set road section at set intervals; according to the traffic flow speed and traffic flow of the set road section in the set time period, determining a first point location having an association relationship with a predicted point location in the point locations based on the topological relationship; and according to the flow information of the predicted point location and the first point location in the set time period, predicting the flow information of the predicted point location in a target time period after the set time period. According to the method, the influence relationship between each point location and the predicted point location can be determined more accurately based on the speed information and the flow information of the point locations, and the flow information of the target time period can be predicted more accurately based on the first point location having the association relationship with the predicted point location.
