The invention discloses a multi-source traffic data fusion method based on a PSO-BP fusion algorithm, and the method comprises the following steps: obtaining the traffic data of a selected intersection based on electronic police equipment, obtaining the traffic data of an upstream intersection of the selected intersection based on checkpoint equipment, carrying out the preprocessing of the obtained data of the electronic police and the checkpoint equipment, and obtaining the traffic data of an upstream intersection of the selected intersection. Performing parameter extraction on the preprocessed data of the electronic police and the checkpoint equipment to obtain three parameters of delay, vehicle speed and queuing length, obtaining three parameters of delay, vehicle speed and queuing length of a road section between two selected intersections based on an online car-hailing information management center, training a PSO-BP neural network based on a PSO-BP neural network algorithm model, and obtaining the data of the electronic police and the checkpoint equipment; and finally, inputting the preprocessed delay, vehicle speed and queuing length parameters into the trained neural network model to obtain the fusion data. Compared with a traditional algorithm, the method has the advantages of being high in data fusion quality and fusion efficiency.
