The ratio of average normal flow of traffic to the saturation flow in a two intersecting road P and Q are 0.3 and 0.25 respectively. If the total lost time per cycle is 11 seconds, then the optimum cycle length as per Webster’s approach in seconds will be ________.
    Correct answer is '47-48'. Can you explain this answer?
    Verified Answer
    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
    yp = 0.3 sec
    yQ = 0.25 sec
    ∴ Y = yp + yQ = 0.3 + 0.25
    Y = 0.55
    The optimum cycle length
    Co = 47.77 sec
