| 摘 要： | 介绍了静态多路径交通分配方法的模型建立和程序设计。并从有效出行路线的确定，最短路权的计算，有效路段的边权及节点点权计算，各路段交通量(简称OD)分配率及分配交通量的计算等方面给出了该模型的算法与程序框图。同时，对该方法在广珠高速公路规划中交通量分配预测的实际应用、软件实现，进行了分析探讨。根据所得结果，表明该方法优于最短路径法，为广珠高速公路的规划建设提供了科学的数据依据。

| Abstract: | The static mul-route traffic assignment model is introduced In this paper. The arithmetic and procedure diagram of the model are given out, from the confirmation of valid trip, the calculation of the shortest link weight and node weight, the calculation of the OD (Origin- Destination) assignment and trip assignment etc. The application of this model on the plan of Guangzhu freeway is discussed, the model arithmetic and software realization are analyzed. With the test result, the scheme is put forward in the paper is proved feasible. It is superior to the shortest route model. It can provide a scientific reference for the plan of Guangzhu freeway. |
