虽然OD车流是从一个区域到另一个区域的车流，但现有的交通分配方法假定OD车流是从一个节点产生并去往一个称为质心的节点。在分配方法中，根本没有考虑区域的形状和构成。本文将对这一假设所引起的误差进行分析。将开发两种交通分配方法来改进现有的方法。在改进的方法中，可以从任意区域内的多个或所有节点生成OD交通流，但所需的数据、计算和存储空间与普通交通分配方法相同。改进方法的适用性将通过假设网络和名古屋市路网的交通分配来验证。
Though the OD traffic flow is the traffic flow from one zone to another zone , the current traffic assignment methods assume that the OD traffic flow is generated from one node and destined to one node known as centroid. The shape and the constitution of zone are not taken into consideration at all in the assignment methods. In this paper, the errors caused by this assumption will be analyzed. Two traffic assignment methods will be developed to improve the current methods. In the improved methods, OD traffic flow can be generated from many or all nodes in any zone, but the needed data, computation and memory space are the same as that of general traffic assignment methods. The fitness of the improved methods will be certified by the traffic assignment of a assumed network and the road network of Nagoya city.
