The invention provides a reversible lane traffic flow determination method and device, and the method comprises the steps: obtaining the real traffic flow data of a target region in a preset time period, and enabling the real traffic flow data to comprise vehicle entry road data and vehicle exit road data; a target directed topological graph is constructed according to a traffic road network of the target area and a reversible lane setting strategy of the target area, the traffic road network comprises a plurality of road sections, and the road sections are composed of roads and intersections; the vehicle driving-in road data and the target directed topological graph are input into a target urban traffic network model, predicted traffic flow data are output, and the target urban traffic network model is obtained by performing parameter adjustment on an initial urban traffic network model according to real traffic flow data; the initial urban traffic network model is constructed based on the driving behavior of the vehicle on the road and the traffic flow conversion rule of the vehicle at the intersection; and determining the congestion condition of the vehicle on the reversible lane based on the predicted traffic flow data.
