Appraisal methodology : Deliverable D2.1
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)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
-
Rapport (övrigt vetenskapligt/konstnärligt)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
-
Rapport (övrigt vetenskapligt/konstnärligt)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.

FALCON III: Defining a performance-based standards framework for high capacity vehicles in Europe
- 2018
-
Ingår i: Proceedings of the 15th International Symposium on Heavy Vehicle Transport Technology, Rotterdam, Netherlands, 2018.
-
Konferensbidrag (refereegranskat)abstract
- The FALCON project (“Freight and Logistics in a Multimodal Context”) is a collaborative effort funded by the Conference of European Directors of Roads (CEDR), and has set out to address ambitious carbon emission reduction targets set by the European Commission. A primary goal of the project is to define a potential Performance-Based Standards (PBS) framework for cross-border road freight transport in Europe. First, a representative fleet of heavy vehicle combinations carrying modular loading units was formulated in collaboration with industry. The fleet was then simulated against a wide range of potential performance standards sourced from various countries. These findings together with expert opinion were then used to draft recommendations for a PBS framework for Europe.

FALCON II: Input For A European PBS Definition : Review Of Vehicle Legislations And Infrastructure Design Criteria
- 2018
-
Konferensbidrag (refereegranskat)abstract
- In Europe, the regulation on weights and dimensions of trucks are complex : European rules are given by EC Directive 96/53/EC as modified by Directive (EU) 2015/719 [1]. These rules apply for international traffic, but countries can decide to add specific national rules. Moreover, these rules are often different from one country to another, due to policy choices and local history. More specifically, the impact of trucks on infrastructure has not always been the primary fact for defining these rules. But in other countries or other research domains, performance based standards (PBS) are used to determine what is allowed, in terms of performance. For example, vehicles may be allowed in terms of their induced damage on bridges (Bridge Formula, see [2]) or dynamic behavior (PBS as in Australia for example). In another context, materials and structures are now often defined in calls for tender in terms of performance (durability, resistance for example). In this context, the work package (WP) C (Fit for purpose road vehicles to influence modal choice) of CEDR project FALCON (Freight And Logistics in a multimodal CONtext) aims at developing Performance Based Standards [3]. For that, the first step is to create a state-of-the art of the European situation concerning vehicle policy and infrastructure. This paper summarizes this work: the first section gives insight on the European vehicle policy. The second section presents the infrastructure catalogue developed within the FALCON project. Finally, these infrastructure elements are characterized in terms of design criteria in Section 3.

Investigation of good practise in road assessment, Heroad
- 2012
-
Ingår i: EPAM 2012Malmö, Sweden, 5–7 September : 4th European pavement and asset management conference. - Linköping : Statens väg- och transportforskningsinstitut. - 9789163714320

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- To manage the road network road managers and operators have to consider existing policies such as the requirement to keep the network in good condition, and to deliver this condition at minimum whole life cost. However, the condition should also meet the expectations of stakeholders. The management process has to optimise the total costs for society, whilst minimizing the effects of given condition levels on safety, reliability, environmental impact, economics and sustainability. This principle and its overall goals are equal for all road managers around Europe. Heroad will investigate the process (the combination of individual components, levels of assessment and the inclusion of a life cycle perspective) to incorporate also new challenges in the asset management. This includes:Look at data collection, assessment and reporting regimesConsidering new challenges (climate change, traffic configuration, new materials, LCC and the focus on road users expectations)Identify and assess the key technical components of these regimes and then determine whether they are best practice or notIdentifying and describe indicators at different assessment levels (for road operators complicated technical parameters are okay, for decision makers and public more understandable indicators that could be built from combination of technical parameters are needed)Then pick out the key good parts and provide advice to the customer on how they could use them.

Overall road asset performance
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)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).

Speed Adaptation Control by Self-Explaining Roads (SPACE)
- 2013
-
Ingår i: Proceedings of the 16th International Conference Road Safety on Four Continents. - Linköping : Statens väg- och transportforskningsinstitut.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes the SPACE project (Speed Adaptation Control by Self-Explaining Roads). This is a European project, funded by ERANET Road initiative, looking at the meaning of self-explaining roads and what types of measures are most effective in achieving the objectives of self-explaining roads. A series of consultations with experts and driver simulation tests were conducted. From this analysis, it was clear that combinations of treatments work more effectively than single treatments and that consistency of treatment is important for drivers.

Integration of New and Emerging Technologies into Data Architectures : Deliverable D3.2
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)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
