摘要
在对现有线控制模型和算法进行分析的基础上提出按照概率思想求解相位差参数的策略。论文确立优化相位差的目标为通过车流在主干道上的停车次数和停车延误最小。建立相位差概率模型时,着重考虑4个影响因素:路段上车流行驶速度不均匀性,主干道上下行流量不均衡现象,相交道路上的转弯车流,短连线上的车辆排队约束。最后,论文用实际算例对建立的模型进行了验证,并对进一步的研究工作给出了建议。
Based on the analysis of the existing arterial control models and algorithms, the tactics of establishing the offset models are put forward according to the probabilistic method. When the offset model is established to minimize the mean stops and the stop delay of the through traffic, the paper takes the four aspects of the actual traffic conditions into consideration. These factors are： the variation of the vehicles＇ driving speeds on the arterial, the inequality of the volumes of the traffic on the two ways of the arterial, the vehicles on the crossing road turning to the arterial, the vehicles queue on the short link. Finally, the paper validates the established model by a practical example and gives some suggestions about the future research work.
