The Fourth Industrial Revolution. Digital Transformation – an opportunity to reposition. Dr Gustav Rohde
The term “Fourth Industrial Revolution” was only coined as late as 2016 by Schwab during the World Economic Forum in Davos. Now – a mere three years later – the scale, speed and impact of new technologies, built around artificial intelligence (AI), machine learning, robotics, the Internet of Things (IoT), big data, autono- mous vehicles, […]
From Taxes to Tolls. Stephen Selwood
Transport pricing — ensuring the price of transport infrastructure promotes efficient use of the network – is one of the Coalition Government’s urban growth agenda priorities and is now included in the National Party’s draft infrastructure plan. But despite building cross-party support, progress is tortuously slow. Stephen will draw on lessons learned in the UK, […]
How do you prioritise work on bridges? Kyle Blyth, WSP
New Zealand has an aging infrastructure network with many iconic and heavily used bridges. It is commonly assumed by Asset Owners that, at the end of their original design life, bridges are in immediate need of replacement. WSP Opus have developed systems with our clients and industry partners to determine the true remaining structural […]
Viewing the State Highway through customer-tinted glasses. Philip van der Wel, Lonrix
The NZ Transport Agency manages the maintenance and renewal of the State Highway Network from a road safety, asset management and value for money perspective. But how well is the Network being managed from a customer point-of-view? This question led the Agency to work with Lonrix Ltd in developing a custom ranking algorithm where […]
Chip loss causing early failure and the long-term effects. Ben Rohde, Central Otago NOC
Central Otago has come to the realisation that we are finding unexpected early failure of some surfacing types – So we have been busy digging deeper into the data and around the network to better understand the cause, effect on expected life, and potential techniques to prolong the life achieved. Over the last year […]
Telling the story: Supplementing pavement deterioration modelling. Kevin Wu, WSP
The pavement deterioration modelling space has been explored for over 20 years now, and there are still advancements being made in the modelling space. The growth of the technical capital in this space has increased dramatically in recent years due to advancements in data and technology. However, how can we ensure that all the […]
IDS Model Updates. Gemma Mathieson, WSP
Robust NZ models were established in 2008, based on 7 years of LTPP data. Demand on our network has dramatically changed over the past 10 years. As part of the 2021 NLTP project, the IDS rutting models have been updated using the latest LTPP data. The probabilistic accelerated rutting model and linear rut progression […]
Treatment prediction using machine learning techniques. Sean Rainsford, Fulton Hogan
This presentation will describe efforts to utilise machine learning techniques, coupled with high speed condition data to construct a prediction model for future treatments. The approach adopted has used treatment assignment outcomes from previous field inspections and detailed investigations. These assigned treatments were used as a labelled training set for the machine learning algorithm […]
Finding the value of materials testing, a field study. David Alexander, Road Science
The civil construction industry in New Zealand is serviced by a large number of laboratories carrying out testing for materials used. The results these laboratories produce are often compared to a specification that gives site engineers the satisfaction they need to ensure that they will stand the test of time. This presentation will examine […]
