交叉口流量分析技术在路段交通量预测中的应用研究

Application Research of Section Volume Prediction with the Technology of Intersection Flow Analysis

摘要: 文章在国省道干线公路大规模升级改造的时代背景下，基于观测站的统计数据结合相邻交叉口的流量观测，提出了路段交通量的反推方法，并对其在交通量预测和公路改建项目技术标准论证上的适应性进行了分析。最后，文章以G105阜阳四十铺至南照段一级公路改建工程为例，详细介绍了该方法在工程实践中的应用情况，并对其具体应用中应注意的问题进行了总结和说明。

Abstract: This article proposed a method to calculate the traffic volume of some given highway segment based on the statistic data from fixed observation point and observation data of some adjacent intersection. Then the applicability of this method was verified in traffic volume prediction and technical standard demonstration. At last, the reconstruction project of some special section of G105 was taken as an example to illustrate how this method was used in practice.
