极大似然法在交通工程中的应用

An Application of Maximizing likelihood principle in Traffic Engineering

本文提出了在已知一个先验的OD出行分布矩阵的情况下,由路段检流量推算OD出行分布矩阵的新方法。根据极大似然法的基本原理,建立了相应的非线性规划模型。实例计算分析表明,该方法是合理而有效的。

In this paper, an new method is put forward, which gives a moat likely origin-destination trip matrix from link traffic volumes with the knowledge of a prior one. In terms of maximizing likelihood principle, a corresponding nonlinear programming model is built up. The practical computation results show the method is reasonable and efficient.
