“…Pioneering work on the NR method can be found in Yakowitz [14] and Karlsson and Yakowitz [15], and some scholars further developed them for traffic flow forecast, for instance, Davis and Nihan [16], Smith and Demetsky [17], Oswald et al [18], Smith et al [19], Qi and Smith [20], and Kindzerske and Ni [21]. Huang et al [22], Lu and Wang [23], Meng and Peng [24], Xue and Shi [25], and Pang and Zhao [26] applied chaos theory in the traffic flow prediction and obtained acceptable results. SVM is a new statistical machine-learning method [27] which has been proved to have stronger learning and generalization abilities than the NN model.…”
