规划网络路段交通量预测模型研究

Study on Traffic Anticipate Model in Traffic programming

交通量预测是公路网络规划过程中的一项重要工作 ,本文在传统的路段交通量预测方法的基础上 ,介绍了路段交通量 OD模型法 ,根据实际道路网的形状 ,通过使路段交通量的预测值与观测值一致来进行模型推算 ,从而计算出规划网络上的交通量。与现有方法相比 。

Traffic anticipation is a important work traffic programming On the base of the old methods,this paper introduces a model to anticipate the traffic of a section of highway It is called section highway traffic OD model. It calculates the traffic by comparing the anticipation and the observation of a section of traffic according to the form of the traffic net,and work out the traffic of the programming net,We can get more accurate result by it.
