The influence of average speed ratio on multilayer traffic network

In traffic network design, operation and management, operation speed is one of the key indicators. However, only a few studies are based on traffic dynamics on networks with the consideration of different operation speeds, and less reflected the influence of multilayer networks, which illustrate and represent different appropriate urban traffic modes. In this paper, we constructed a multilayer traffic network model with time weighted adjacency matrix. Then with the study of the influence of different network operation speed ratios on the corresponding characteristics of the comprehensive traffic network, we can clearly know that the change of network operation speed ratio will have very obvious impact on the travel time between nodes, the average travel times, the cooperation strength, the accessibility, and the network community numbers. This research has connected the rencent related study of multilayer traffic network and network operation speeds, the findings of the study afford to improve the current design and operation of traffic integrated models, and can provide some suggestions for urban and urban agglomeration development. •The change of network operation speed ratio (θ) will make the average travel time value decrease at different rates, which can make the cities more closely linked together.•With the change of θ for different network structures, the change of community number is very different and noticeable.•The time weighted adjacency matrix is proposed to analyze the influence of network operation speed ratio.
