Real‐time vehicle detection and counting of multiple types is a difficult problem. To solve this problem, study presents an efficient method based on single shot (SSD) to construct system. The proposed named Fast‐SSD first combines the Slim ResNet‐34 with Single Shot MultiBox Detector. Then authors limit location prediction at each cell in feature map modify network. When input size picture 300 × 300, achieves accuracy 76.7 mAP PASCAL visual object classes 2007 test set. network can be implemented speed 20.8 FPS GTX650Ti. Furthermore, they obtain centre point type which detected by model image set virtual loop detectors specify range. number vehicles calculated when passes detector. Results show that 99.3% classification 98.9%.
