【摘要】：为了便于信号控制策略的实施,针对路网中不同状态的交叉口,考虑子区内交叉口的同质性和关联性,提出了基于不同拥挤程度的路网动态分区方法.首先考虑相邻交叉口的交通关联度和相似度,建立了路网动态分区模型;然后结合谱图理论设计了动态分区算法,根据特征向量元素,对路段、交叉口的拥堵程度进行划分;最后提出了动态子区划分评价准则.算例结果表明,本文提出的方法既能有效地保证相关性较强的交叉口划入同一子区,又使得各子区内部路段的拥堵程度比较均衡,有利于各种不同拥挤程度的子区信号控制方案的选择和实施,对于交通信号控制方案的设计有实际的指导意义.
[Abstract]:In order to facilitate the implementation of signal control strategy, considering the homogeneity and relevance of intersections in different states of road network, a dynamic partition method based on different congestion degree is proposed. Firstly, considering the traffic correlation and similarity of adjacent intersections, the dynamic partition model of road network is established, and then the dynamic partition algorithm is designed based on spectrum theory, and the congestion degree of road sections and intersections is divided according to the characteristic vector elements. Finally, the evaluation criterion of dynamic subregion division is proposed. The numerical results show that the proposed method can not only effectively ensure the intersections with strong correlation into the same sub-area, but also make the congestion degree of each sub-area more balanced. It is beneficial to the selection and implementation of various sub-area signal control schemes with different congestion levels and has practical guiding significance for the design of traffic signal control schemes.
