Improved Model of Multipath Assignment and Quick Algorithm───Node Assignment Algorithm

本文对动态多路径交通分配模型进行了改进，提出了该模型的快速算法──节点分配算法，并详细阐述了节点分配法中的网络处理、分配节点排序及参数确定等问题。节点分配算法的采用，大大提高了多路径交通分配方法的速度及容量，使之能在超大规模网络的交通规划、交通控制及交通诱导系统中应用．

he multipath traffic assignment model is modified,A quick algorithm of this model(Node Assignment Algorithm)is presented.The methods of network analysis ,arrangement of nodesfor assignment ,and paranieter determination are described in detail.Speed and capacity of multipath as-signment algorithm is largely improved and the multipath assignment is enabled to apply to traffic plan-ning,traffic control and road guidance systems of large-scale network because of adopting node assign-ment algorithm.
