Given that an intersection has four phases with critical volumes of 300, 500, 400, and 700 vehicles per hour respectively, calculate the total cycle time and effective green time if the lost times for each phase are 4, 3, 5, and 6 seconds and the amber time is 2 seconds.
💡 Hint: Calculate green time using total critical volume and cycles.
At a signalized intersection with two phases, phase one has a critical volume of 800 and phase two has 600 vehicles per hour. If the cycle length is 100 seconds, and the lost time for phase one is 4 seconds and for phase two is 2 seconds, what is the actual green time allocated to each phase?
💡 Hint: Start by finding the effective green time for each phase.
