【摘要】 交通分配是交通规划中的一个重要步骤。在交通规划方法相对成熟之后， 交通界的人士逐渐把注意力更多的转向交通控制与诱导，由此提出了动 态交通分配（ＤｙｎａｍｉｃＴｒａｆｆｉｃ Ａｓｓｉｇｎｍｅｎｔ）。本文首先总括了动态交通分 配的定义及其在交通控制与诱导中的位置和作用。然后列举了目前为止 常用的几种动态交通分配模型。通过对动态交通分配模型的分析，本文认 为对于解决交通控制与诱导问题，动态交通分配在其前提和结构上存在 不可克服的障碍。最后本文从智能的角度提出了解决交通控制与诱导问 题的新的思路更多还原

【Abstract】 Traffic assignment is an important step in transportation planning. After the mature of transportation planning,traffic engineers pay more attention on traffic control and route guidance. Dynamic traffic assignment(DTA) is promoted for this situation. Firstly, the definition and the framework of DTA,DTA’s postion and it’s role in traffic control and route guidance are presented. Several DTA models are listed and analysed. The conclusion that there exist some unconquered shortness of the DTA models comes from the analysis about DTA model’s assumes and their structures. Finally,a new idea on solving traffic control and route guidance problem is given from the point of view of intelligent traffic system(ITS).更多还原
