4 cards from this section. Quick, good the night before a test.
What is a traffic signal cycle?
Think of the sequence of lights.
What is meant by lost time in traffic signals?
Consider delays when waiting for a signal.
What defines a cycle in traffic signals?
Think of it as a full loop of signals.
True or False: Lost time refers to the actual delay experienced by vehicles.
Consider the function of traffic signals.
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.
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.
Compare the traffic volume with the saturation flow rate directly.
