| 摘 要： | 静态交通分配模型不能很好地反映实际交通状况,而动态交通分配模型计算复杂、计算量大。本文基于动态用户状态均衡条件下,提出一种动态和静态交通分配的折衷方案———动态状态交通分配模型,给出了该模型计算路段平均队列长度和平均通行时间的公式,以及动态状态交通分配算法;最后给出一个运用于正常工作日动态交通分配的例子进行模型检验及其检验的数值结果。

| Abstract: | Based on the dynamic user equilibrium conditions,this paper proposes a dynamic traffic assignment model which is a compromise between dynamic traffic assignment model and static traffic assignment model.The authors formulate average length of queue of vehicles and average travel time in a section of highway,and a feasible algorithm in discrete time is presented.The algorithm needs less calculation than dynamic traffic assignment and is more precise than static traffic assignment.A numerical example is used to illustrate the application of the proposed model in the dynamic traffic assignment for normal working day and numerical results are presented. |
