REG; Enabling the Transport Sector to Succeed. Suzy Ratahi, Timaru District Council

 

The Road Efficiency Group (REG) continues to build on the One Network Road Classification and data quality work to enable more consistent levels of service, a better understanding of each RCA performance and more evidence based investment business cases to be developed.
The ONRC system used for the 2018/21 National Land Transport Programme (NLTP) is being enhanced to create a One Network Framework (ONF) for the 2021/24 NLTP development. Coupled with the REG business excellence, asset management competency, data quality frameworks and new RCA performance reporting is enabling an increase in investor confidence across the transport sector through changing the way decision making is made.
All aspects of the REG programme are developed under a co design – co delivery model supported by evidence.
This presentation will focus on how the REG Focus 2021 programme is helping the sector to succeed and will consider;

  1. The Focus 2021 programme
  2. What REG is focused on during 2020
  3. Where REG will focus during 2021

Suzy, Chair of the REG Leadership Group has been involved in local government for eight years with a further eight years experience in the contracting industry prior.  This has resulted in having a practical based approach to solution resolution.
Suzy enjoys the challenge of balancing customer expectations with the understanding the ability to pay for the appropriate level of service.
Once an early challenger to the REG program, Suzy now understands the need for the outcomes that are being achieved through the REG work program.  While the agile development style that is being achieved through the cross sector partnership that is REG can be challenging, it demonstrates a true collaborative approach to realising enduring excellence.

A simplified approach to forward works plan modelling to address deterioration rate uncertainty. Ted James

 

Deterministic, network level forward works plan modelling provides an analysis simplification relative to  probabilistic modelling.  But the unexplained performance variability issue is important both  for  pavement maintenance practitioner and for budget management.  Obviously  addressing variability might introduce an increase in computer run time, a significant issue for large networks analysis.
It is argued that a simplified model approach can address forward works plan risk levels sufficiently for field use, while also  keeping computer run times within practical limits. Direct measurement and algorithm based analyses are compared. Austroads LTTP  outputs are used to assess  the analysis complexity necessary for field application. Experience with implementation of an Indonesian  National Highways pavement management system provides evidence.

Ted is a Civil Engineer with 50 years experience in pavement engineering spanning Australia, Libya, Malaysia and Indonesia in management, resident engineer and team leader roles in the fields of pavement design, asphalt materials, pavement materials manufacture, highway construction and supervision, technical guidance, governance and asset management systems.

Getting it right – continually improving the sectors data quality. Tony Lange

Data is increasingly important in underpinning the New Zealand’s transport sectors approach to consistent levels of service, asset management and investment decision making.
The Road Efficiency Group (REG) is still working hard to help the sector improve the quality of New Zealand’s transport-related data to support evidence-based decision-making and lift investor confidence through robust data.
The latest 2018/19 data quality assessment has shown a favourable improvement in data quality across the country; however, there is more work to be done by the sector to continually improve their data to support their asset management, AMPs and LTP’s.
While REG is annually assessing and reporting the data quality results nationally and for each Road Controlling Authority, we are also focused on helping the sector to continually improve its data quality.
As there is still a long way to go to get it right, more recently, REG has increased its focus on the production of guidance and case studies to help RCAs overcome their data quality challenges.
This presentation will focus on how we can achieve better data quality across New Zealand and will consider;

  1. Where data quality is improving and where there are still some challenges.
  2. How some RCAs have been able to improve their data quality.
  3. The tools and guidance we have prepared to help RCAs, what are we doing now and what’s next?

Tony is the new lead for the REG Evidence and Insights working group, having recently taken over from Dawn Inglis, and a Senior Investment Auditor with NZTA tasked with the assessment of maintenance and Low Cost Low Risk programmes across NZ. Tony has been in this role for 13 years and prior to this was an Area Engineer for Christchurch City Council. Some would say he was a poacher and is now a gamekeeper. Tony enjoys rugby, cycling and motorsport.

 

The Asset Management Data Standard (AMDS) project. Michaela James, NZ Transport Agency


The Asset Management Data Standard (AMDS) project is a collaborative project between the NZ Transport Agency and the Road Efficiency Group (REG) to improve the management of land transport infrastructure asset information, so we can make the best decisions about New Zealand’s land transport assets – our roads, highways, bridges, cycleways and what sits on and under them.
The project will develop and implement a national data standard for land transport assets. It will establish a common language the sector can share. A way of defining and describing land transport assets, their attributes, characteristics, properties, location and performance to enable efficient and effective end-to-end life cycle asset management.
Promoting greater data standardisation and sharing in land transport will realise significant benefits through improved efficiencies, network planning and resilience.
The AMDS project will prepare the foundations for the land transport sector to be able to work towards a digital engineering and BIM (Building Information Modelling) approach.

Michaela is a civil engineer with a strong interest in asset information and data management. Currently Asset Data Consultant to the Asset Management Data Standard (AMDS) project, she been with  the NZ Transport Agency for 10 years. As Asset Information Manager, then Senior Asset Manager she managed the annual High Speed Data contract, the Long Term Pavement Performance contract and the annual State Highway Valuation.
Prior to this she gained experience in a variety of disciplines in the civil domain, variously as a structural engineer, drainage design engineer and project manager.

The use of genetic algorithms in Road Maintenance Optimisation. Fritz Jooste, Lonrix

The solution to the problem of finding an optimal set of road maintenance strategies under a multi-year budget constraint is exceedingly complex. Over the past few decades many different approaches to this problem have been implemented – these include linear programming, dynamic programming and – more recently – genetic algorithms. The latter type of model is particularly interesting since it mimics the evolutionary principle of selecting the “fittest” solutions from a population of candidate solutions, and then progressively evolving towards a near-optimal solution. A key feature of genetic algorithms in the road maintenance context is that some formulations allow the optimization problem to be approached at the segment and network level at the same time. Genetic algorithms are also capable of handling complex constraint sets that may not be feasible in more traditional optimization techniques. In this presentation, a highly visual and interesting introduction to genetic algorithms will be presented. The background and key elements of genetic algorithms will be presented together with some example problems and solutions. The strengths and weaknesses of genetic algorithms will be discussed in the context of road maintenance optimization. The presentation concludes with specific suggestions for how genetic algorithms can potentially be used in deterioration models in New Zealand.

Fritz Jooste has been working in the field of pavement design and asset management for more than 20 years. He earned his PhD from Texas A&M University in 1997 and since then has been involved primarily in research and with the development of systems related to pavement design and asset management. Fritz is a founder and director of Juno Services Ltd and Lonrix Ltd.
