CRITERION AND MEASUREMENT OF TRAFFIC FLOW SYSTEM COMPLEXITY: CHAOS, FRACTAL AND COMPLEXITY

摘要

In this paper, the analysis on the complexity characteristic of traffic flow system is deepened through introducing characteristic quantities of complexity, such as Lempel-Ziv complexity, statistical complexity, approximate entropy, and combining the criterion methods of chaos & fractal. The Lyapunov index, relevancy dimension and their complexity characteristic quantities of actual traffic flows are calculated. By virtue of the calculation results, some useful conclusions are obtained.
