The Network Operating Framework (NOF)
Aims for the presentation
• Provide a quick introduction to Network Optimisation Framework (NOF)
• How NOF draws on signal information and
• How NOF can help inform and enhance signalling
The History
Based on some Dutch thinking and “link and place” BUT driven from Traffic Signal work in Melbourne
NOF – A change in approach
A new way of thinking about transport!
Moving People and Goods (not Vehicles) & time of day
Balancing the competing demands for limited road space
Seeing transport as supportingbroader community goals
Thinking about “Networks” rather than sites or routes
NOF - What is it? (in essence = collaboration)
• Well, really it is a process around what we should be doing already. Process Framework
• Having open discussions across the whole network and agreeing the aims as a means of enhancing transport, common language
• But there as a “tool” to demonstrate the outcomes and effects on transport.
• WorkshopsBUT…it is not yet an added layer of planning!
• One-Network view across modes and ownership
• Agree Strategic transport objectives• Links Strategy and Operations and Capital
Improvements• Demonstrates the trade offs on a
constrained network • Consistent & clear informed decisions (mobility)• Network Optimisation & Unlocking Network
Potential• Integrated Planning

Strategic Network Principles that deliver Strategy
Promote walking in, to and from areas of high pedestrian activity
Improve level of service on key cycle links to activity areas
Promote greater public transport connectivity into activity areas
Freight has unrestricted access across arterial network, priority on PFN
Promote preferred traffic routes to avoid conflicts with abutting land usePreferred Traffic Route:
Provides for longer distance general traffic as a preferred alternative to other arterials with a land use conflict. Traffic Route (Arterial Road):
Provides for longer distance general traffic. Local Primary Access Route:
Provides access routes to/from local destinations within the local area. May also provide circulation routes/ Gateway into the activity centre.
Local Secondary Access Route: Collects and distributes between primary local access routes.
Local Destination Route: Predominantly local access to abutting properties. Low levels of traffic/restricted access.

Level of service How well we are going against the “plan”?
How NOF draws on traffic signal systems for workshops
• Uses Signal engineer knowledge and data to fill in wider knowledge gaps.
• Can use signal system outputs to help determine “throughput volumes” and “Levels of Service” equivalents.
• Uses data and expertise to enable multi modal project testing and trade offs to be understood.
How NOF could expand and support current signalling practices
• Multimodal (people and goods not vehicles)
• Based on agreed collective strategic objectives, so signalling can demonstrate strategic delivery.
• Illustrates relative mode priority and trade offs, by location and time of day. Helps signal engineers informs and justifies interventions and actions.
• Will illustrate project outcomes by mode, across networks and in relation to strategic intent.
• Can allow iterative project content to be developed.
How NOF can inform signalling
• Identifies knowledge and data gaps
• Applies degrees of confidence to data and results identifying short comings.
• Can help enhance project content and avoid some network wide failures.
• Uses LoS equivalents and people movement that might inform the evolution of signal thinking.
