1.)create a time-space plot for the eight vehicles, placing distance on the y-axis and time on the x-axis. Note that the location of the stop bar for the subject intersection is at a distance of y = 346 feet. Show the stopbar in your plot. 2. Visualize the time-space diagram with the range y = 200 feet to 400 feet and x = 20 seconds to 120 seconds and try to answer the following questions:

a. Is there movement in the queue while the vehicles are supposedly stopped?

b. Which vehicles are directly affected by the red display?

c. Which vehicles are affected only by the behavior of their leading vehicles?

d. Which vehicles are not affected by either the red display or their leading vehicles?

e. How far upstream does the queue extend
