耦合节点选择对网络交通动力学的影响分析

Influence of Coupling Node Selection on Network Traffic Dynamics

由于耦合网络能够更加准确地刻画真实的交通系统,学者们对其中的交通拥堵问题进行了广泛而深入的分析和探索。为了提高耦合交通网络的通行能力,研究其结构对交通动力学特性的影响,提出了两种网络耦合机制:选择度大节点进行耦合和选择度小节点进行耦合。研究结果表明,选择度小节点进行耦合,其网络通行能力最大。

Because coupled networks can describe real traffic systems more accurately, scholars have conducted extensive and in-depth analysis and exploration on the problem of traffic congestion.In order to improve the traffic capacity of coupled networks and study the influence of its structure on traffic dynamics, two node selection and coupling mechanisms are proposes in this paper: large degree nodes selected and small degree nodes selected.The results show that the maximum network capacity is obtained under the coupling mechanism of nodes with small degree nodes selected.
