Challenge Problems
Push your limits with advanced challenges
Given that a signal has a cycle length of 60 seconds, green time of 40 seconds, yellow time of 5 seconds, and lost time of 2 seconds, calculate the saturation flow rate if saturation headway is 2.5 seconds.
💡 Hint: Start with calculating effective green time and use it to find the capacity.
If an intersection experiences a traffic volume of 1200 vehicles per hour, determine whether the current setup can handle this volume if the saturation flow rate is 1500 vehicles per hour.
💡 Hint: Compare the traffic volume with the saturation flow rate directly.
