Steady speed states for the Kerner–Klenov traffic flow model in the flow–density (a, b) and in the space gap–speed planes (c). In (a, b), L and U are, respectively, lower and upper boundaries of 2D regions of steady states of synchronized flow. In (b), J is the line J whose slope is equal to the characteristic mean velocity vg of the downstream front of a wide moving jam; in the flow–density plane, the line J represents the propagation of the downstream front of the wide moving jam with time-independent velocity vg. F, free flow; S, synchronized flow
