摘    要:针对智能交通系统(TTS)基础上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旋点交叉口设置有交通信号控制(Traffic Signal Control)时的动态配流模型,给出了对现有的通过Frank Woife算法所得的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。

关 键 词:智能交通系统  动态配流  交通信号控制  交叉口

Abstract: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.
Keywords:intelligent transportation system  dynamic traffic assignment  traffic signal control  optimal control  algorithm
