摘　　要：针对传统交通控制系统中控制策略无法动态响应交通状态变化的问题,提出了一些评价区域交通状态的指标,并基于这些指标提出了一种基于层次支持向量机的区域战略交通控制策略优化方法,设计了两种层次支持向量机优化结构。最后基于VISSIM4.2和Matlab 7.01平台,开展了一些模拟试验来验证所提出方法的性能。仿真结果表明,基于组合二叉树的层次支持向量机的优化方法能够更有效地、准确地响应于时变交通流。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 t...
