3. Traffic Signal Design (15 Points) An intersection has a three-phase signal with the movements allowed in each phase and corresponding analysis and saturation flow rates shown in the following table. Calculate the optimal cycle length (Webster's method) and corresponding effective green times of each phase. Assume lost time is 4 seconds per phase.
