What would be. Also determine the resulting speeds when flow i4 near zero and when the flow is ai capacity. Derive the equation for density as a function of percent occupancy without the use of the text. Assuming a reasonable relationship between speed and density, convert the density contour map shown in Figure 7.
Give particular attention to the regions around the 40 and 60 density contour lines. Interpret the percent occupancy contour map shown in Figure 7. Interpret the density contour map shown in Figure 7. Identify the bottlenecks and assess the severity of congested locations as shown in Figure 7. Design and conduct a field experiment that will demonstrate the typical shock wave phenomena of a single lane at a signalized intersection see Figure 7.
Assume that the field experiment described in Problem 9 is undertaken at a signalized intersection having a second cycle with 67 percent effective green time. The backward Macroscopic Density Characteristics Chap.
How far upstream of the stop line will the stopped queue of vehicles extend? Is this approach oversaturated? What effect would that have on the maximum stopped queue distance?
Congestion is observed at a freeway bottleneck location from until A. Maximum queueing extends 2 miles upstream and is observed at A.

Assuming no rear stationary shock wave, identify and calculate the velocities of all other shock waves. Draw a hypothetical density contour map that includes all types of shoc;k waves and describe the traffic flow situations.
Estimate the total travel time for the situation presented in Table 7. Estimate the total delay time per lane during one cycle of the traffic signal described in Problem Assume a density of vehicles per lane-mile in the stopped queue and a constant arrival rate of vehicles.
What proportion of the vehicles will have to stop? Estimate the total travel time in the congestion upstream of the freeway bottleneck described in Problem Assume an average density of 80 vehicles per lane-mile in the congested region.
Estimate the traffic demand at the bottleneck for the problem described in Table , except use an optimum density value of 50 rather than 60 vehicles per" lane-mile.

However, the shock wave pattern downstream of the signal deviates from the earlier pattern. Currently, there are two types of flow density graphs. First consider the time of queueing t 3 - t 1.
