Evaluation and network performance
There is limited information about monitoring, feedback, evaluation and improvement mechanisms as part of network operation planning. It is broadly understood that the operation performance of a road network is regularly monitored to help inform strategic objectives. However, it is not being regularly undertaken as part of specific NOPs and the associated interventions that are implemented or assessments of their effectiveness.
One example where intervention review is regularly undertaken is with Signal Route Reviews to ensure they are achieving what was intended and not causing other undesired implications.

Phase 7 - Evaluation of Plans and Network Performance in Figure 2 p18 and write-up on p27-28 states: "The Framework is an iterative process – the review of outcomes requires the clear identification of objectives and performance requirements against which to assess the effectiveness of interventions deployed to improve the operational performance of road networks. This requires:

Section 3.7 - Phase 7 - Evaluation of Plans and Network Performance p11-14 provides the following recommended changes to this phase of the NOP framework: Change the wording of the Phase 7 Elements/Inputs from ‘Annual review of network operations plans on a rolling five year time horizon’ to ‘Review of network operation plans on an as needs basis’. | |
Guide to Traffic Management Part 4: Network Management Strategies (2020) | Section 5.8 - Evaluation and Feedback p70: "Post-implementation of the NOP should be conducted. The review of implemented treatments checks how they have contributed to reducing the performance gaps. The network operation objectives and the road use priorities should also be reviewed, as community and government values can change over time. Based on the review, the NOP may need to be revised." |

Phase 3 - System planning, at a glance box p35 states: "System planning is undertaken through a combination of studies and stakeholder engagement." | |
MRWA Network Operation Planning Framework (2014) | Section 2.9 - Phase 8: Evaluation and Feedback p16 indicates the following around post-implementation review and NOP updates: Post-implementation reviews of the NOP treatments should be conducted to check how they have contributed to reducing the performance gaps and meeting defined performance targets. The network operation objectives and the road use priorities should also be reviewed, as community and government values change over time. > Based on the review, the NOP may need to be revised. A NOP may also be updated to incorporate the impacts of new planned projects, investigate a wider impact area and address different planning horizon timeframes. |
A comparative study of four network operations planning frameworks guidelines (2010) | Phase 9 – Evaluation of plan and network performance section p22 states: "This phase includes ex-post evaluation of the Network Operations Plan and refining elements of the plan by revisiting the individual phases in the Network Operations Planning Process in light of the evaluation results." |
Section 3.7 - Performance reporting p24 indicates that the performance measures will be reviewed. | |
