Question
Transcribed Image Text:Traffic on the eastbound approach of a signalized intersection is traveling at 32 mi/h, with a density of 45 veh/mi/In. The
duration of the red signal indication for this approach is 30 sec. If the saturation flow is 1,900 veh/h/In with a density of
53 veh/mi/In, and the jam density is 127 veh/mi/In, determine the following.
(a) the length of the queue at the end of the red phase (in ft)
Your response differs from the correct answer by more than 10%. Double check your calculations. ft
(b) the maximum queue length (in ft)
Your response differs from the correct answer by more than 10%. Double check your calculations. ft
(c) the time it takes for the queue to dissipate after the end of the red indication (in s)
Your response differs from the correct answer by more than 10%. Double check your calculations. s
