“…Although classification-based methods perform well in detecting traffic congestion, this approach only classifies images into two states: congested and uncongested, ignoring the various complex scenes that occur during traffic congestion. In addition, the literature [11,27,28] proposed real-time discrimination methods for urban road traffic congestion. He et al [11] used a road congestion index and network congestion index to, respectively, measure the degree of congestion on urban roads and road networks.…”

“…Lam et al [27] proposed the mIOU method, which detects traffic congestion by calculating the ratio of the overlap area between two images taken at a certain time interval and the union of multiple bounding boxes. Since the instantaneous mIOU proposed in the literature [27] performs poorly when the time interval is short, Liu et al [28] proposed a new weighted mIOU method. First, the boundary box generated by YOLOv4 is used to automatically crop the image to generate the region of interest, and then, the weighted average of the current and previous instantaneous mIOU values is taken to improve the application of the mIOU method in traffic congestion detection.…”

“…This framework is low-cost and off-the-shelf as it can be directly deployed on the system with surveillance cameras. Compared with our previous works on congestion detection [7]- [9], [11], we propose to consider multiple camera sites for congestion detection. Moreover, we consider traffic forecasting in this paper.…”
