中文摘要 |
针对智能交通系统 (ITS)项目中主要基础理论之一的动态交通分配问题, 在现有研究成果的基础上, 提出了更接近真实路网的多起点多讫点交叉口设置有交通信号控制 (TrafficSignalControl)时的动态配流模型, 给出了对现有的通过Frank Wolfe算法所得到的DUO配流解进行修正的原则, 最后的算例表明由修正后的模型和算法所得到的DUO配流解满足TSC约束. |
英文摘要 |
The instantaneous dynamic traffic assignment model for multi origin and multi destination road network with traffic signal control(TSC)at its intersection is putforwarded and the equivalence is demonstrated that the dynamic user-optimal(DUO)route choice problem can be converted to a optimal control program with a defined objective function.Considering the TSC constraint,the DUO assignment solution obtained from the existing Frank-Wolfe algorithm is revised so that the final DUO solution is consistent with the TSC constraint.A numerical example is presented indicating that the model and algorithm in this paper yields realistic results. |
