4.7 Use and Implementation of the NOP

The NOP guides the operational services and activities that relate to the day-to-day management of the road network. The NOP may also include a prioritised list of projects that can be implemented through project-based programs.

The NOP can also be used to guide general decision-making on a range of operational, customer, project proposal, planning, and policy issues. Decisions that are likely to impact the operation of the network can be tested against the NOP to determine the extent to which a possible response will support (or otherwise) the operational objectives of the NOP.

Network FitCriteriaExample
Good network fitThe total worst and best cases are both positive values and the difference between the two cases is less than the worst case value (e.g. +3 to +5 has a difference of 2 which is less than the worst case value of 3).
Positive network fitThe total worst and best case are both positive values and the difference between the two cases is greater than or equal to the worst case value (e.g. +1 to +3 has a difference of 2 which is greater than the worst case value of 1).
Neutral network fitThe total worst case value is negative and the best case value has a higher absolute value (e.g. –3 to +4); i.e. the midpoint of the range is positive.
Negative network fitThe total worst case value is negative and the best case value has a lower absolute value (e.g. –5 to +1 or –7 to –4); i.e. the midpoint of the range is negative.
