通道OD矩阵推算算法的应用研究

An Application of Calculation of Corridor OD Flows

交通规划中很重要的一环就是交通流调查。通过分析通道OD和断面流量的关系提出一种可通过断面流量推算OD矩阵的理论方法。并描述了将双向交通流分解为单向交通流进行推算的过程 ,给出了通道OD递推公式和相应条件。

Traffic flow investigation is an important step in the traffic planning. In this paper, the relationship between corridor OD flows and section flows is analyzed, and a method is proposed to calculate corridor OD flows via road section flows. The procedures to divide bi-directional flows into two single directional flows are discussed. The formulae for OD flow calculation are derived.
