公路网路段交通量预测模型研究

A Study on the Model of Traffic on the Highway Net

在传统的路段交通量预测方法的基础上 ,提出路段交通量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。与现有方法相比 ,可得出精度更高的结果。

On the basis of the old methods, the authors introduce a model to anticipate the traffic of a section of highway. It is called section highway traffic OD model. It calculats the traffic through a comparison between the anticipation and the observation of a section of traffic according to the form of the traffic net. A more accurate result thus can be obtained.
