Question

The total effective green time required for an intersection is \(40\) seconds, and total lost time per cycle is \(20\) seconds. The cycle length is

• A. \(40\) seconds
• B. \(50\) seconds
• C. \(60\) seconds
• D. \(80\) seconds

Hint:

Traffic signal cycle: \[ \boxed{ \text{Cycle Length} = \text{Effective Green Time} + \text{Lost Time} } \]

Answer 1

The Correct Option is C

Step 1: Recall the relation for cycle length. The cycle length is the sum of the effective green time and the total lost time. \[ C = G+L \] where - \(G\) = Total effective green time - \(L\) = Total lost time

Step 2: Substitute the values. \[ C = 40+20 = 60\ \text{seconds} \] Hence, \[ \boxed{60\ \text{seconds}} \] Therefore, \[ \boxed{(C)} \] is the correct answer.
