Question 1

What is green splitting?

  • Allocating green time based on traffic lights
  • Dividing green time among flow phases
  • Increasing green time for pedestrian safety

💡 Hint: Think about how traffic flow is managed.

Question 2

True or False: Effective green time is the time available without accounting for any lost time.

  • True
  • False

💡 Hint: Recall the formula we've discussed regarding effective green time.

Challenge Problems

Push your limits with challenges.

Question 1

Consider an intersection with the following parameters: Total cycle time is 100 seconds, lost time is 4 seconds, and the critical lane volume for the critical phase is 600 vehicles per hour. Compute the effective green time and the green split if the total critical volume at the intersection is 1500 vehicles per hour.

💡 Hint: Make sure to calculate effective green time first, then apply the green splitting formula.

Question 2

If a pedestrian needs to cross a width of 15 meters at a speed of 1.5 m/s with a minimum start-up time of 3 seconds, determine the total pedestrian green time required.

💡 Hint: Break down the calculation into components: crossing distance and speed, plus start-up time.
