Neural Network Model of Freeway Traffic Flow Based on Rough Sets

利用粗糙集能够处理模糊、不确定知识和神经网络对非线性函数具有任意逼近能力的优点,提出一种粗糙集和RBF网络集成的动态系统建模算法。并利用这种方法建立具有复杂动态特性和不确定性的高速公路宏观交通流动态模型,仿真结果表明了该方法的有效性。

Rough set is a powerful mathematics tool, which can deal with fuzzy and uncertain knowledge, and RBF neural network has the ability to approach any nonlinear function precisely. A dynamic modeling method is presented using the rough sets and RBF network integrated technology for complex system. The method is applied to model the freeway traffic flow system with complex dynamic characteristics and uncertainties. The simulation results prove the validity of this method.
