The marginal computing devices transmits counting results of motorway traffic flow to the cloud, and store them in the traffic-flow time series in the library, and then calculates average arrival time of traffic flow at adjacent nodes and tests whether the time series of traffic flow between two adjacent nodes apart from average arrival time are stable based on the morphological similarity distance. If the time series of traffic flow difference is not smooth, probability of traffic anomaly at adjacent nodes of motorway should be calculated. If the abnormal traffic probability is greater than the threshold, the abnormal traffic at adjacent nodes shall be considered, otherwise it will be deemed as normal transportation.
