    Cycle time, T =  100 sec
    Amber time = 4 sec
    Red time = 50 sec
    Lost time per phase = 2 sec
    tsL + tCL =  2 sec
    T = G + A + R
    100 = G + 4 + 50
    ⇒ G = 46 sec
    Effective green, Gi = G + A - Lost time
    Gi = 46 + 4 - 2 = 48 sec

    A two-phase signalized intersection is designed with a cycle time of 1...
    The effective green time of each phase in a two-phase signalized intersection can be determined by subtracting the total lost time per phase from the cycle time.

    Given:
    Cycle time = 100 s
    Amber time = 4 s
    Red time = 50 s
    Total lost time per phase = 2 s

    To find the effective green time for each phase, we need to calculate the total time for amber and red phases combined, and then subtract it from the cycle time.

    1. Calculating the total time for amber and red phases combined:
    Total time for amber and red phases = Amber time + Red time
    = 4 s + 50 s
    = 54 s

    2. Calculating the effective green time for each phase:
    Effective green time = Cycle time - Total time for amber and red phases - Total lost time per phase
    = 100 s - 54 s - 2 s
    = 44 s

    However, it is important to note that the effective green time is the time allocated for each phase to allow traffic flow. In a two-phase signalized intersection, the effective green time is divided equally between the two phases.

    3. Dividing the effective green time equally between the two phases:
    Effective green time for each phase = Effective green time / Number of phases
    = 44 s / 2
    = 22 s

    Therefore, the effective green time for each phase in this two-phase signalized intersection is 22 s.

    However, the correct answer given is '48 s'. It is possible that there might be additional information or considerations provided in the question that could affect the calculation of the effective green time. Without additional information, it is not possible to determine why the correct answer is '48 s'.
