The invention discloses an intersection vehicle detection method in a fog computing environment, and the method comprises the steps: improving a YOLOv5n network through employing an R-D module and a re-parameterization SPP, training the improved YOLOv5n network through employing a vehicle detection data set, and obtaining a vehicle detection model; training a DeepSORT feature extraction network by using the training vehicle tracking data set to obtain a multi-target tracking model; a fog platform architecture is built, vehicles passing through all road intersections serve as a data generation layer, cameras, vehicle detectors, vehicle detection models and multi-target tracking models are deployed at all the road intersections to serve as fog layers, and the vehicle detectors call the vehicle detection models and the multi-target tracking models at all the road intersections. Vehicle identification detection and tracking are realized, and the detection efficiency and precision are improved. The invention further provides a bus priority passing method, and efficient control over bus priority passing at the intersection is achieved.
