河北省公路网交通量预测技术研究

为研究适合于河北省公路网络的交通量更新方法，利用最大可能相对误差上限和约束域最小化对OD反推技术中的流量观测点选取进行建模，可提高交通量更新的精度，相关研究成果改善了河北省交通量预测模型，能很好地运用于河北省公路交通规划、管理和决策。

Study on Prediction Technique of Traffic Volume in Hebei Provincial Highway Network

The paper studies on the method of traffic volume alteration fitted for Hebei provincial highway network, carries on the modeling of the selection of flux observation point in OD back-stepping technique by the upper limit of maximum possible relative errors and the minimization of constrained domain, improves the precision of traffic volume alteration. The research result improves Hebei provincial traffic prediction model, and can be applied in Hebei provincial highway traffic planning, management and decision.
