Question 1.
What is the purpose of green splitting?
Show hintHide hint
Think about traffic flow and efficiency.
Question 2.
Define effective green time.
Show hintHide hint
Consider what happens during a traffic signal cycle.
3Question 3.
What is the purpose of green splitting?
- To allow vehicles to move freely
- To allocate effective green time
- To increase traffic congestion
Show hintHide hint
Think about the goal of traffic management.
4Question 4.
True or False: Amber time is factored into the calculation of effective green time.
- True
- False
Show hintHide hint
Consider what happens when a signal changes.
Question 5.
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.
Show hintHide hint
Calculate green time using total critical volume and cycles.
Question 6.
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?
Show hintHide hint
Start by finding the effective green time for each phase.
