交通流诱导以交通流预测和实时动态交通分配为基础,如何更精确地来预测交通流的变化情况是其中的一个核心问题.文中用BNN动态来刻画交通流的演化过程,介绍了BNN动态的概念及演化动态方程,并分析BNN动态的零点的稳定性,给出了一个算例进一步验证BNN动态的稳定性.通过简单的算例,在BNN动态的基础上对道路中的交通流进行分析和预测,进而对车辆进行诱导,从而达到交通管理的目的.%The route guidance is based on the traffic flow predictive and real-time dynamic traffic distribution, therefore, how to predict the traffic flow change is one of the core problems.In this paper,we use BNN dynamic to depict the traffic flow evolution process.Firstly, we introduce the concept and evolution function of BNN dynamic, then, analyze the stability of the zero point of BNN dynamic function.Finally, a numerical example is presented to verify BNN dynamic stability.Through the simple example, we can analyze and forecast the road traffic which achieve the purpose of transportation management.
