Delivering upon the ObjectivesSystems Engineering and Operations AITPM Lunch and Learn 21 March 2013 Andrew Somers
Why focus on operations? • We invest in Managed Freeways, or other ITS initiatives, on the basis of the benefits to the community • Those benefits to the community are realised during the operational phase • The new tools/assets/systems create the opportunity for benefits • …but it is the use of the tools/assets/systems that creates the benefits • Operations phase = benefits realisation phase
The best things in life don’t come for free • Remember, operations phase = benefits realisation phase • If we underinvest in the operations phase, we will struggle to achieve the full benefits • ITS projects have a different balance of capital and operating costs. Compare O&M costs as a % of whole of life discounted cash flow: • Traditional road project: capital 83%, operations 17% • Managed freeway elements: capital 58%, operations 42% • If benefits realisation phase = revenue phase, this works well • However, if capital is available and recurrent funding is squeezed, this leads to some pressures
Implications • Getting the operations and maintenance right matters • Benefit realisation • Whole of life costs • Our greatest opportunity to start to get this right is at the start of the life cycle, as for other changes to projects
What does this mean for MF? • Clear understanding of objectives • Understand what services are needed to achieve those objectives • Then look at the options for those services • each service, multiple technologies • each technology, multiple services • Starting with tools and retrofitting services leads to inefficiencies and missed opportunities • Cannot afford to operate and maintain inefficient MF implementations
USDOT: golden rules for systems engineering • Start with Your Eye on the Finish Line • Stakeholder Involvement is Key • Define the Problem Before Implementing the Solution • Delay Technology Choices • Divide and Conquer (complexity) • Connecting the Dots – Traceability
Assess: Policy and Network Analysis • In developing and implementing a “solution”, we are by definition addressing a “problem” • What are the problems on our transport network that we are seeking to address? • Why are they problems? • How big are the problems? • What is the nature of the problems? • …problem compared to what? • Main Roads Network Operations Planning Framework
Select: Project Objectives • Now that we understand the problem, what do we want our solution to achieve? • State Business Case and Infrastructure Australia processes provide guidance in generating and prioritising solution options • Managed Freeways is a flexible toolkit of ITS-enabled services • …it’s not the answer to every problem on a freeway • …but it will probably be at least part of the answer for many of them
Develop: Concept of Operations • A Concept of Operations describes the features of a proposed system from the perspective of an individual or organisation who will be involved in the operations of the system. • A project Concept of Operations process is intended to: • develop a common vision; • capture the operational needs of key stakeholders; • work towards developing a shared understanding on key interrelationships, roles and responsibilities for the operations of the system; • help identify key operational risks and work with stakeholders to validate/ inform the underlying operational assumptions; and • develop a reference document to support feasible operations and successful operational outcomes.
Develop: Functional and Technical Requirements • Functional requirements set out what we want to achieve, for each of the ITS-enabled services • Technical requirements set out required performance and characteristics of the technology elements required to deliver the ITS-enabled services, as well some process requirements • Requirements are not design! • Of course in practice, such a black and white distinction is not always so simple to make • Alignment of technical requirements across projects assists to create a more consistent base of installed ITS • Eg. Leverage more flexible VMS technologies
Develop: Concept or Solution Design • The ITS solution design should identify how the project will fit in with the existing infrastructure and systems as an end to end solution • Any major development required, any specific challenges and how commissioning will be undertaken should be well known and understood by this stage • Two areas of focus: • Integration into end to end systems • Integration into the roadside (especially if other contracts) • Adoption of an ITS control systems platform has a big impact on what “solution design” means for ITS
Deliver: Detailed Design and Implementation • Generally a bundled task for a contractor • Rare to have construct only for ITS • Coordination will be required • Network provider • Control systems provider • Civil contractors • Power • … • The design and implementation will strongly influence maintenance costs • What are the opportunities to incentivise for this?
Deliver: Testing, Integration, Commissioning • This is a critical part of any ITS project • For ITS, physical completion ≠ practical completion • Ready for operations = practical completion • Testing and commissioning strategy needs to be risk-focussed and target effort where it is most rewarding, to identify faults as early as practical in the process • Do we test off-site systems prior to installation? • What hold points are required? • Development of testing and commissioning plans needs to commence during design phases
Deliver: Validate • What does validation mean? • Is the commissioned system meeting the stated business requirements? • What happens if the answer is no?
Operate: Maintenance • The planning for maintenance must start well before the completion of delivery • We must also consider our obligations for design for safe maintenance • Where possible, involve the maintainer early • Good documentation assists to reduce maintenance costs • ITS systems have the capability to provide continuous data on operation and performance • We can leverage this to target maintenance effort to best achieving required performance • … but must have in place the systems and processes to do so
Operate: Operations, Evaluation, Improvement • If you have deployed an active management system, then you must actively manage it • Some functions are automated, some cannot be automated, some aren’t feasible to automate • The good news is that an active management systems offers the opportunity for continuous improvement • Hence, evaluation is not only about telling what has happened, but also about making it even better (improvement)
What are MF services? • Something that adds value • to individual road users • to the community as a whole • Technology enabled, not technology • Understanding services means that we can get the right tools right • Service relies on the use of the tools • Let’s look at some options for a queue protection service
What does this mean for managed freeways? • Understand the problem that we are trying to address • Select the ITS-enabled services that we need to deploy • Focus on the service outcomes, not the technology • Establish clear objectives, functional requirements and a concept of operations • The solution should be the most effective and efficient way of meeting the objectives
The next generation of UK MM MM1 – MM-HSR – ‘MM heavy’? MM2 – MM-ALR – ‘MM light’ Similar objectives, services and outcomes – different technologies, infrastructure and layouts
What has changed? Operational strategies Permanent conversion of hard shoulder to running lane – All Lane Running
What has changed? Technology / infrastructure Manage speed and lane use: • When: ↑ spacing from average 800 m to max 1500 m • How: from overhead lane to mainly verge Provide emergency refuge areas: • When: ↑ spacing now up to max 2500 m Similar services – different physical implementation Emergency refuge area Speed cameras Driver information CCTV Detectors
