摘　　要：为了准确反映网络的交通行为,提出一种基于复杂耦合网络的改进交通动力学模型。对双层结构耦合网络的信息产生和传递情况进行分析,并探讨了复杂耦合网络信息交通过程的特征,引入层间控制参数和层内控制参数分别控制不同层之间信息传递的速度和路径选择,重点考虑了层间传递信息的损耗代价情况。在所提动力学模型的基础上,研究了耦合网络中信息交通过程涌现出的统计学特征。结果表明:提出的耦合网络交通动力学模型中所有节点都能够产生和传递信息,随着层内控制参数的增大,网络交通容量出现先增大后减小的变化趋势,当层内控制参数为3.8时,耦合网络交通容量达到最大。研究结果对交通网络中的拥塞问题的缓解具有指导意义,可以通过调整控制参数来增大网络的交通容量。In order to accurately reflect the traffic behavior of the networks,an improved traffic dynamics model based on complex coupled networks was proposed.The information generation and transmission of a coupled network with a two-layer structure were analyzed,and the characteristics of the information traffic process of a complex coupled network were discussed.Interlayer control parameters and intralayer control parameters were introduced to control the speed and path selection of information transfer between different layers,respectively,and the loss cost situation of information transfer between layers was considered.On the basis of the proposed dynamical model,the statistical characteristics of the information traffic process emerging in the coupled network were investigated.The results show that all nodes in the proposed coupled network traffic dynamics model are capable of generating and transmitting information,and with the increase of the intralayer control parameter,the traffic capacity of the network appears to increase and then decrease,and when the intralayer control parameter is 3.8,the coupled network traffic capacity reaches the maximum.The results of the study are of guiding significance for the alleviation of congestion in traffic networks,and the traffic capacity of the network can be increased by adjusting the control parameters.
