Explain how the total control delay for each lane group at an intersection is used to determine the total control delay for the entire intersection.
What will be an ideal response?
Having determined the average stopped delay for each lane group, the average stopped delay for any approach can be determined as the weighted average of the stopped delays of all lane groups on that approach. The average intersection control delay is found in a manner similar to the approach delay. In this case, the weighted average of the delays at all approaches is the average stopped delay at the intersection.
