Appraisal methodology : Deliverable D2.1
- 2023
-
Reports (other academic/artistic)abstract
- This report represents INFRACOMS deliverable D2.1 Appraisal Methodology. It builds upon the deliverables of INFRACOMS Work Package 1 which identified the information needs, gaps and priorities of NRAs in terms of their approach to data collection and monitoring, and a list of current and emerging measurement technologies. This report includes a review of several commonly-used appraisal methodologies that can be used to evaluate the effectiveness, suitability and potential impact of new technologies for an organisation. These methodologies include Technology Readiness Levels (TRLs), Cost Benefit Analysis (CBA), Life Cycle Cost Analysis (LCCA), Risk Assessment, and Multi-Criteria Decision Analysis (MCDA). Elements of these commonly used methodologies are included in the INFRACOMS Appraisal Methodology. The report also includes key highlights from a workshop with NRAs conducted in January 2023 which also fed into the design of the appraisal methodology. The INFRACOMS Appraisal Methodology described here is designed around the technology use case, that is, a particular application of a technology by a NRA. It incorporates three core processes for Pre-Evaluation, Evaluation and Case Studies of technology use cases. It also includes processes for NRAs to define their strategic and technical priorities so that the appraisal process can be tailored to addressing their individual requirements, as identified from Work Package 1.

Current Practice, Future need and Gap Analysis : Deliverable D1.1
- 2023
-
Reports (other academic/artistic)abstract
- This report is INFRACOMS first deliverable D1.1. It addresses the “Understanding of information needs and gaps” component of the project. The aim has been to identify the current priorities and future needs of NRAs for the management of carriageway and bridge assets, specifically in terms of their approach to data collection and monitoring. The approach has been to establish existing knowledge via a review of previous projects, current best practices and standards in data collection and inspection, and a review of current business processes, NRA strategies around data collection and digitalisation etc. The report identifies a set of key imperatives for carriageway and bridge assets covering Availability, Reliability, Environment, Economy and Safety. Each of these is supported by the collection of key condition data, which is used to report technical parameters and performance indicators that can be combined to assess the ability of the asset to meet its key imperatives. A wide range of technologies are identified, which are currently applied to collect the data that supports this assessment.The consultation shows that there are also gaps between the desired and the current capability for the assessment of these assets. These include gaps in the data, challenges in the ability to collect the data, gaps in the application of the data that is already collected etc. A review of emerging technologies shows that there are tools and technologies that could help to fill these gaps. These could overcome the limitations of current technologies, better integrate new data sources, provide greater flexibility in using current and new data, and provide better analysis. They include remote sensing, Internet of Things (IoT), crowdsourcing, and advanced data processing/visualisation.

Report on state-of-the-art data assessment and visualisation methods : Deliverable D3.1
- 2023
-
Reports (other academic/artistic)abstract
- Effective analysis and visualisation of data is critical for the efficient application of the data provided by carriageway and bridge condition monitoring technologies. It supports better decisions in relation to asset reliability, availability, safety, economy and environment. This report discusses the link between the data provided by monitoring technologies on the properties of assets and how the collected data can be analysed and visualised to provide value in decision support. The next step in the report is to use this understanding to develop an appraisal system which could enable technologies in the INFRACOMS technology database to be appraised (scored) in relation to their abilities for data analysis, visualisation, integration and use in decision support.The presented system is referred to as the D3.1 scoring system. It consists of four components covering data visualisation, data analysis, integration within current data architectures and potential for practical decision-making. The present D3.1 report primarily examines the components pertaining to data visualisation and data analysis, while the exploration of the other two components, data architecture and decision support, will be carried out in the D3.2 report. It is proposed that the D3.1 scoring system could be used to appraise the capability of monitoring technologies to support asset management decisions, and would become an integral component of the INFRACOMS Appraisal Toolkit. It will also be used to further filter the current INFRACOMS Technology Database 2.0 technologies as part of the Appraisal Toolkit as INFRACOMS completes the development of the toolkit/database within WP2.

The Poroelastic Road Surface (PERS) : Is the 10 dB Reducing Pavement within Reach?
- 2016
-
In: Materials and Infrastructures 1. - Hoboken, NJ, USA : John Wiley & Sons. - 9781119318583 - 9781786300294 ; , s. 253-268
-
Book chapter (other academic/artistic)abstract
- In September 2009, a consortium of 12 partners started to develop a durable, safe and extremely noise-reducing poroelastic road surface (PERS). PERS is a novel pavement type, containing a substantial amount of rubber (new or recycled, e.g. from scrapped tires) and an elastic resin (like polyurethane). The work is carried out in the framework of the PoroElastic Road Surface for Avoiding Damage to the Environment (PERSUADE) project and has the financial support of the European Commission (EC).The project duration is 6 years, and in the first 3 years, the main focus was on the development of a mixture with a number of criteria: a high noise reduction, a sufficient raveling resistance, a sufficient binding to the sublayer and an acceptable drainability. The research of the consortium involved the testing of numerous samples with a variety of laboratory tests and led to two promising mix formulas. The consortium has started with the construction of five "full-scale" test tracks in five different countries and these tracks will be monitored. The PERSUADE project includes the study of environmental and economic aspects.

Improving the mechanical properties of a low noise section
- 2006
-
Reports (other academic/artistic)abstract
- The goal of this innovation initiated in a later phase of NR2C WP2 activities was to evaluate (and eventually to improve) the functional and the mechanical properties (durability) of low-noise poroelastic layers built on cement concrete blocks. Laboratory and site tests were performed for the evaluation of these properties. So, it contributes to the concept "green infrastructure", by the reduction of noise nuisance coming from traffic.

Possibilities to reduce tyre/road noise emission on paving stones and other block surfaces
- 2007
-
Reports (other academic/artistic)abstract
- Block surfaces, made of stones or cement concrete, have a widespread use in today's cities and towns. However, there are many examples where the use of block surfaces has led to complaints from people living or working close to streets with such pavements; complaints that mostly focus on the extra noise generated by the traffic on such surfaces. The EU-project SILENCE has recognized this sensitive balance and therefore included a subtask with the title “Noise reduction for paving stone surfaces for streets of high cultural or historic importance”. The objectives are stated as:To produce a ranking in relation to noise of commonly used types of paving stonesTo develop and test quieter types of paving stones

Overall road asset performance
- 2013
-
Reports (other academic/artistic)abstract
- The HeRoad project has investigated the road asset management situation and what practises exist to collect performance measurements in Europe. This has been done in a view from the operational level using a holistic perspective, in the sense that multiple assets and the cross relation between those are included. HeRoad’s approach by addressing the need for condition performance measurements can be justified with some words from (AASHTO, 2011); “What´s measured gets done; if you do not measure results, you cannot tell success from failure.” This implies that the view of investigation has been from the operational level more than from the strategic level (bottom–up).

Hi-SPEQ : Developing the Technical and Quality Requirements for High-speed Condition Surveys of Road Networks
- 2016
-
In: Transportation Research Procedia. - : Elsevier BV. - 2352-1465. ; , s. 2956-2965
-
Conference paper (peer-reviewed)abstract
- High speed surveys have become a key source of information to support condition assessment and management of pavement assets. These surveys can be applied network wide to obtain data on the surface condition and structural robustness of the pavement. However, these advances bring challenges to road administrations in determining the most appropriate survey to specify for their networks, in selecting the equipment, and in ensuring that the condition parameters delivered will be suitable to support asset management decisions. Although standards have been developed for some of the measurements provided by high speed systems, the focus tends to be highly technical, often not considering the wide ranging needs of routine network level implementation.The HiSPEQ project has the objective of developing guidance and advice to help road administrations to understand high speed road survey equipment, and to help them in specifying the survey requirements, quality regimes and processing procedures. The project has considered high speed survey data that can be used to assess pavement structural robustness. It has investigated the measurement of pavement shape, visual condition, deflection and structure. Via review of current specifications both within and outside the EU, and direct consultation with practitioners and administrations, the project has proposed a set of core requirements for high-speed surveys of pavement surface and structural condition.

Integration of New and Emerging Technologies into Data Architectures : Deliverable D3.2
- 2023
-
Reports (other academic/artistic)abstract
- To appraise the ability to integrate the data provided by a specific technology into an existing data architecture this report commences with the development of an approach to describe the "ideal" data architecture, that can integrate various types of data from new and emerging technologies to facilitate decision making. The data architecture forms a pipeline from raw data creation/delivery to data ingestion, data organization, data analysis and visualisation, until information that is useful for decision making. We then review two existing data architectures as examples in the context of the proposed data architecture pipeline. From the understanding of the two sides – the data properties of technologies and the capabilities of data architectures – we develop an appraisal scoring process to evaluate the ability to integrate the new data into the existing data architecture.To generalize this approach, the report presents a list of questions that can be used by stakeholders to help understand the data architecture used by any NRA (not only limited to the selected examples) when conduct the appraisal. We also develop an appraisal scoring process to evaluate the potential of the technologies to support practical decision making.The outcomes in this report (D3.2) and the previous one (D3.1), complete the INFRACOMS appraisal (scoring) system for the aspects of: data analysis, visualisation, integration into data architecture and potential support for decision making (forming part of the overall appraisal process). An example application of the process is presented for the case of acoustic emission monitoring the wire break in steel cables. In addition, the process has been applied to further technologies in the INFRACOMS database 1.0, and provided in the appendix. It is anticipated that refinement, and further guidance
