My goodness, that sounds like a really complicated entry! Can someone explain what the queue storage ratio aims to measure and how it applies to signals work? In what instances can I use this calculation?

The Queue Storage Ratio (QSR) is the Maximum Back of Queue (HCM Chapter 16 Appendix G) divided by the Available Queue Storage Length. If the QSR is equal to or greater than 1.0, blockage will occur. The HCM procedures do not account for this blockage in the computation of delay.
