Abstract: Some indexes for evaluating the regional traffic condition were proposed. On the basis of there indexes a regional traffic control strategy optimization method based on the hierarchical support vector machine(H-SVM) was suggested and two optimized structures of HSVM were designed. The simulations were performed on the platform of VISSIM 4.2 and Matlab 7.01 to test the proposed method. The results show that the optimization method based on the combined binary tree SVM could efficiently and accurately respond to the practical timevarying traffic flow.
