ABSTRACT

For decades, research shows that network structure determines statistical properties and dynamical characteristics, even for directed networks. However, as observed in traffic flow networks, traffic flow (edge weight) on roads (edges) affects traffic network state. To evaluate the impact of network structure and flow distribution on network statistics, we introduce a method of network efficiency for weighted traffic flow networks considering weights on edges in calculation. Furthermore, this paper adopts 6 network structures (including the random network, scale-free network, small-world network, grid network, the road network in Beijing, and the road network in Xiamen) and 3 kinds of flow distributions (Normal distribution, Power-law distribution and exponential distribution) to analyze the impact on network efficiency. For analyzing the impact of network structure and flow distribution on traffic network efficiency, two strategies are adopted: 1.) network structure comparison under a certain flow distribution, 2.) flow distribution comparison under a certain network. The work covered in this paper provides an effective tool for comparing network structure and flow distribution, which can analyze the statistical properties of real traffic networks reasonably.
