The queue length (in number of vehicles) versus time (in seconds) plot for an approach to a signalized intersection with the cycle length of 96 seconds is shown in the figure (not drawn to scale).At time = t = 0, the light has just turned red. The effective green time is 36 seconds, during which vehicles discharge at the saturation flow rate, s (in vph). Vehicles arrive at a uniform rate, v (in vph), throughout the cycle. Which one of the following statements is TRUE?

• A. v = 600 vph, and for this cycle, the average stopped delay per vehicle = 30 seconds
• B. s = 1800 vph, and for this cycle, the average stopped delay per vehicle = 28.125 seconds
• C. v = 600 vph, and for this cycle, the average stopped delay per vehicle = 45 seconds
• D. s = 1200 vph, and for this cycle, the average stopped delay per vehicle = 28.125 seconds
