An application of the CUSUM algorithm to freeway incident detection based on two contiguous detectors

Abstract: The CUSUM (cumulative sum of log-likelihood ratio) algorithm is a detection algorithm that shows potential for the improvement of incident detection algorithms because it is designed to minimize the mean detect delay for a given false alarm constraint and it can also detect changes with different patterns. In this study, the CUSUM algorithm was applied to freeway incident detection by integrating traffic measurements from two contiguous loop detectors and the nonstationarity of traffic flows. The developed alg… Show more
