基于ARMA交通流量预测控制器的设计

Design of the ARMA Traffic Flow Forecasting Controller

交通流量的预测与控制是现代交通中的一项重要任务,本文基于自动控制理论,提出几种交通流量的动态预测方案并进行比较;最后给出了最佳系统控制框图及主要参数。并对一组实际的交通流量进行了预测。仿真结果表明,本系统能较准确地预测交通流量,但只适用于预测短时交通流量。

As the important task in the modern traffic is the forecasting and controlling of traffic flow,the author has showed us the best system control diagram and main parameter by proposing some performance forecasting plans for the traffic flow and compared them,which are basing on the automatic control theory.With an actual traffic flow being forecasted,the simulation result showed that： the system forecast traffic flow can be unequivocally detected,but only short time traffic flow.
