The invention relates to a traffic flow statistics method in intelligent traffic. In the prior art, the accuracy of vehicle identification is insufficient, and the efficiency is not high. According tothe method, an SSD and a ResNet in a neural network are adopted, and the method is established with a traditional target tracking CamShift algorithm and comprises a vehicle detection method and a vehicle tracking method. According to the vehicle detection method, firstly, an SSD network is established, the SSD obtains a plurality of feature maps of different sizes, different aspect ratios are adopted for default frames on the same feature layer, the robustness of the default frames to the shape of an object is enhanced, and the position and the target type are regressed while the SSD trainingis carried out. According to the vehicle tracking method, a continuous self-adaptive expected movement algorithm is adopted to track a vehicle identified by a first frame of a single-time movement visual network detector. According to the method, the vehicles can be detected more accurately for statistics, the vehicles can be prevented from being lost through tracking to be counted again, and theobtained traffic flow data are more accurate.
