Challenge Problems
Push your limits with advanced challenges
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.
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.
