摘要
针对现有OD矩阵估计方法的不足 ,本文讨论了一种新的有效的估计方法 ,它包括一个路段流量的预处理过程 ,以消除路段观测流量的不相容 ,然后经过流量加载和卸载两个逆过程 ,进行反复迭代 ,最终得到再现路段交通量的OD矩阵 ,文中例证了该方法的有效性。
The paper discusses an effective method for estimating OD matrix from traffic counts based on the deficiency in existing methods. It includes a preparation for link traffic volumes so that the inconsistency in observed link traffic counts can be eliminated. Through two reverse processes, namely, loading and unloading flows, and repeated iterations, OD matrix which can reproduce observed link traffic volumes is obtained. In the end, an numerical example is provided so as to illustrate the effectiveness of the presented method.
