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 constrain

The ability to predict freeway accident likelihood promises significant benefits to freeway operations. However, the develop- ment of such prediction models has proven to be very challenging because of the random nature of accidents, as well as the i

Even though the MOBILE5 model has been widely used in air-quality analysis, it cannot be used in the evaluation of transportation improvements that result in a reduction of vehicle acceleration or deceleration. In this study, least-square regression

To evaluate the impact of ITS technologies for incident management systems, a three-level incident delay model was proposed to estimate the average delay caused by incidents. In this model, incident delay was expressed as a function of incident durat

The CUSUM (cumulative sum of log-likelihood ratio) algorithm is an optimization-based algorithm that is attractive for many applications because it can minimize detection delay and can explicitly incorporate the characteristics of processes before an
