定性动态概率网络 交通状态预测 交通状态改进
2012/11/5
交通问题已经成为了制约城市发展的一个主要问题.城市的交通状态是可以预测和加以改进的.有效的交通状态预测在一定程度上能优化交通状态,减少交通堵塞.定性动态概率网络(QDPNs)是目前进行动态地推理不确定知识领域最有效的模型之一.提出了一种基于定性动态概率网络的交通状态预测及改进的方法,该方法从系统的角度对城市的交通状态进行建模,通过推理,能够找到交通问题的症结,以便采取有针对性的措施来解决交通拥堵问...
首先从理论上分析有限采样影响下秩减估计器的波达方向估计性能，然后基于信号(或噪声)子空间的正交投影矩阵扰动定理，分别推导秩减估计器方位估计偏差的一阶和二阶闭式表达式，在此基础上给出其方位估计均方误差、偏置以及测向成功概率的理论计算公式，最后针对若干重要的秩减估计器给出数值实验，实验结果验证了所提理论推导的有效性。
