关于流量传播约束的分析

ANALYSIS ON THE FLOW PROPAGATION EQUATIONS

本文的主要内容是给出了动态交通分配 (DTA) 模型中的几种不同条件下的流量传播约束,分析了实际中车辆的行为方式,并导出了这几种流量传播约束之间的递进关系;在此基础上说明了这些约束在建立模型中的应用,由于大大减少了模型的变量,从而使动态交通分配 (DTA) 模型及算法也可随之简化。

In this paper, several flow propagation equations under different conditions in the dynamic traffic assignment (DTA) model are proposed. Analyzing the behavior of the vehicles in practice, we formulate the relationships among these flow propagation equations. Furthermore, the application of these equations in establishing of DTA model is introduced, which may simplify the model and the algorithm with fewer variables.
