2 cards from this section. Quick, good the night before a test.
What is the definition of cycle time?
Think about how long it takes for all lights to complete their sequence.
Define green splitting.
Consider how traffic might be distributed at an intersection.
What is the primary benefit of green splitting?
Consider why we need to adjust times for busy times.
True or False: Lost time is irrelevant to effective green time calculation.
Think about what happens at the end of a green light.
Using the provided critical lane volumes and total cycle time, calculate the green split for a lane with a 500 vph volume. Assume total effective green time is 120 seconds.
Make sure to calculate the total critical lane volume first!
Analyze a scenario where adding exclusive pedestrian signals reduces delays by 20%. How might this impact overall traffic flow?
Think about how pedestrian crossings can change driver behavior.
