摘要
建立了描述路段交通量变化的状态方程及相关约束，在最短路径算法的基础上，给出了多起点多讫点以及Ｏ－Ｄ量随时间变化路网的动态用户最优配流解（ＤＵＯ）算法．仿真结果验证了模型及算法的有效性．
The state equations describing the change of traffic volume on links in road network and the relative constraints are established.Based on the shortest route choice algorithm,the dynamic user-optimal traffic assignment algorithm for the model proposed in this paper is suitable for large-scale road network with many to many origin-destination and time-dependent O-D volums.A numerical example indicates that both the model and algorithm are efficient.
