| 摘 要： | 基于自动控制理论,文章提出一种路段短时交通量的动态预测算法。以历史交通量观测数据为输入,下一时刻交通量预测值为输出,构造了单输入单输出的离散时间动态系统,设计了反馈控制回路和自适应PID控制器对预测结果进行修正。实例分析表明,该算法能较快跟踪交通量的变化,实时修正算法,能实现时间和空间上的移植。

| Abstract: | Based on autocontrol theory,an algorithm of short term traffic flow forcasting is proposed in this paper.Considering the history traffic volume as input,the result of next time volume forecasting as output,It constructs a real-time dynamic forecasting system,and designs a feedback circle and a adaptive controller to revise the prediction.Through test,this method has an excellent performance in tracking the changing volume,it can update the model at the same time as it gets new data,so it is transplantable. |
