Fig. 8From: Resilience and systems- A traffic flow case examplePerturbed system state vector time response (a) and the system space phase (b) indicating the system state vector return to the optimum state (ρA = 78, qA = 3900) for D = 1. The density visibility is limited on the scale of Fig. 8a because of its relatively smaller numbers. For full visibility of the same density distribution see Fig. 7bBack to article page
