Complex network model is established based on traffic flow data,then its topology are analyzed from the perspective of matrix.The conclusion shows that the degree distribution of the location nodes of this complex traffic network accords with the power law distribution,i.e.,the BA scale-free network.With data processing,the clustering coefficient is large,the average path length is small,and the network is small worldwide.The eigenvalue of Laplace matrix obtained by MATLAB analysis shows that the synchronization ability of this network is weak.According to the conclusion of the study,relevant traffic control departments and enterprises can make reasonable arrangements and adjustments to public transportation and shared transportation,further improve the traffic efficiency and the utilization rate of public resources,and alleviate the environmental pollution caused by congestion and resource waste.
