Drag and Drop 10 points possible (graded) Qavery Keard Help The following figure 1 b shows a time-space diagram of a link with a traffic signal at its downstream end for two successive cycles. We assume that the system is described during all times by a triangular flow-density diagram, shown in figure la and that Kinematic Wave Theory is valid at all times. Complete the time-space diagram by dragging the letters correspondint to (i) the different states from the flow-density plot (A, B, C, D or E) and to (ii) the slopes of the shockwaves (a,b,c,d,e). No calculations are required. It is not necessary that you use all the letters. As an example, states "A" and "B" and slope "a" are shown in figure 16 .
