It is investigable how the system scaling affects the system complexity degree. The traffic flow system is taken in this paper as an illustration to study this question. First, the Lempel-Ziv algorithm is introduced for accurate depiction of the complexity degree of the traffic flow system. We gain 3 actual sequences and 20 s period traffic flow sequences on the basis of the measure of the traffic flow data; we gain 5 traffic flow sequences whose periods are between 1-5 min by simulating the traffic flow system. By calculating the complicacy of the 11 sequences, we obtain two hypothesis-, the complicacies of the same system are different under different time scalings; negative correlation exists between the complicacy and the time scaling of the system.
