The ratio of average normal flow of traffic to the saturation flow in ...

Concept:

The optimum signal cycle is given by as per Webster’s Method

Where L = total lost time per cycle, in sec

= 2n + R (n = number of lanes and sum of R is all red-time)

Y = Sum of Ratio of normal flow to the saturation flow.

= y₁ + y₂

y₁, y₂ are the ratio of normal flow to saturation flow in direction 1 and 2.

Where q₁ = Normal flow on each approach

q₂ = Normal flow on each approach

S = saturation flow per unit time.

Calculation:

Given:

L = 11 sec

y_p = 0.3 sec

y_Q = 0.25 sec

∴ Y = y_p + y_Q = 0.3 + 0.25

Y = 0.55

The optimum cycle length

C_o = 47.77 sec

Similar Civil Engineering (CE) Doubts

If the normal flows on two approach roads at an intersection are respectively 500 PCU/h and 300 PCU/h, the saturation flows are 1600 PCU/h and 300 CPU/h, the saturation flows are 1600 PCU/h on each road and the total lost time per single cycle is 16 s, then the optimum cycle time by Webster’s method is

View answer

A signalized intersection operates in two phases. The lost time is 3 seconds per phase. The maximum ratios of approach flow to saturation flow for the two phases are 0.37 and 0.40. The optimum cycle length using the Webster’s method (in seconds, round off to one decimal plac e) is _____ Correct answer is '60.87'. Can you explain this answer?

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 scal e).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?

View answer

The uniform arrival and uniform service rates observed on an approach road to a signalized intersection are 20 and 50 vehicles/minutes, respectively. For this signal, the red time is 30 s, the effective green time is 30 s, and the cycle length is 60s. Assuming that initially there are no vehicles in the queue, the average delay per vehicle using the approach road during a cycle length (in s, round off to 2 decimal places) is _______ Correct answer is '12.5'. Can you explain this answer?
