The DoS provides an indication of the overall performance of each intersection and is
a better overall indicator than either the level of service or queue length.
When the DoS exceeds 80 to 85 per cent overflow queues start to become a problem
(as shown by the cells shaded grey with bold text in the table below). Satisfactory
intersection operation is generally achieved with a DoS of 70 to 80 per cent or less.
Performance data for all major intersections within the proposal footprint are
described further in Appendix C.
