摘要
提出了一种基于噪声可见性函数(NVF)的交通流量异常预警算法。该算法在交通流量预警中引入图像处理中的NVF,将交通流量的车速数据视作图像上的像素点,将该点前8周同一时刻的数据作为该像素的邻域,利用NVF来计算该处允许车速波动的范围。试验结果表明了该算法的可行性。
An algorithm for abnormal traffic flow warning is proposed based on ty function. The noise visibility function is introduced, which views the data of flow as pixels in an image, and the data 8 weeks ago at the same time as the neigh pixels. The allowed fluctuation range of traffic flow is calculated by means of the function. Test results show feasibility of the algorithm. a noise visibili- current traffic borhood of the noise visibility
