Consider a stretch of road. The relationship between flow and density (called Flow - Density graph) is

Consider a stretch of road. The relationship between flow and density (called Flow - Density graph) is plotted below: Flow ( 2000 1756 1500 1250 750 500 250 From the graph you see, calculate: The free-flow speed of the road, we call up. The capacity. The critical density. The jam density we call kjam Density velkm) Link flow-density relationship 84 Explain how to calculate the speed from the Flow - Density graph. What is the speed of vehicles that gives the maximum flow? If you observe cars from the road and see a flow speed of 75 km/h, what is the flow rate on the road? The graph above is plotted under the assumption that speed on this road is given by u = uo-up* kjam Give the relationship between Flow and Density (q in function of k) and between speed and flow (u in function of q). Draw the fundamental diagram in the speed-flow plane.
