      <title>Sediment metal enrichment and ecological risk assessment of ten ports and estuaries in the World Harbours Project</title>
      <link>https://trid.trb.org/View/1707034</link>
      <description><![CDATA[Ten global harbours were assessed for sediment quality by quantifying the magnitude of anthropogenic change and ecological risk. Anthropogenic change (enrichment) was high for Derwent River and Sydney estuary, moderate for Santander Harbour, Rio de Janeiro and Dublin Port, slight for Hong Kong, minimal for Darwin. All 10 enrichment indices used showed similar results. Derwent River sediment was rated at high ecological risk, followed by Sydney and Santander estuaries with moderate risk. Auckland and Darwin sediments exhibited minimal ecological risk and sediment in the remaining harbours (Dublin, Hong Kong, Ravenna, Ria de Vigo and Rio de Janeiro) were assessed at slight ecological risk.The extraordinary variety of environments and types/quantities/qualities of data investigated resulted in as much a critique and development of methodology, as an assessment of human impact, including unique techniques for elemental normalisation and contaminant classification. Recommendations for an improved technical framework for sediment quality assessment are provided.]]></description>

      <title>Testing an innovative predictive management system for bus fleets: outcomes from the Ravenna case study</title>
      <link>https://trid.trb.org/View/1509973</link>
      <description><![CDATA[The European Bus System of the Future (EBSF_2) is a research project funded by the European Union with the aim of developing a new generation of buses across Europe. The goals are to increase the attractiveness and efficiency of buses by testing advanced operational and technological solutions. Among these are more comfortable internal layouts, the implementation of a standard IT architecture, intelligent garage procedures, energy-efficient auxiliaries and green driving assistance systems, all of which are being tested in several demonstrators. This study focuses on the innovative features of the methodology and test process adopted in Ravenna, Italy, where a demonstrator is being used to improve predictive maintenance management. The demonstrator involves maintenance software used to analyse data from CANbus and sensors to assess oil quality, detect potential breakdowns and, on this basis, replace spare parts in advance. The system also detects which substances contribute to poor oil quality. The study describes performance before and during the implementation of the demonstrator in relation to various impact areas: maintenance, operations, fuel consumption, costs, staff training and the efficiency of the intelligent transport system in processing data. The achieved results are reported with the aim of providing advanced knowledge for applications beyond EBSF_2.]]></description>

      <title>A Predictive Maintenance System for Bus Fleets: Innovation and Research from the Case Study of Ravenna</title>
      <link>https://trid.trb.org/View/1494635</link>
      <description><![CDATA[The paper introduces an innovative Predictive Maintenance (PdM) system to assess the quality of engine oil for buses, tested in Ravenna (Italy) within the “European Bus System of the Future – EBSF_2” project, funded by the European Union. The system relies on PdM software linked to oil sensors and filters, installed on a test fleet and using a specifically designed Information Technology (IT) architecture. The system enables continuous assessment of the oil quality, which is highly predictive of engine performance. It thus detects potential or prospective breakdowns and plans replacement with spare parts when needed or ahead of regular schedules. The system also detects which substances, namely metals, and problems in general cause poor oil quality. The paper describes the system and its IT architecture, the testing scenarios, the assessment methodology, based on a comparison of performance with and without the PdM system, and the preliminary outcomes. Thus far, results (associated with various areas of impact – maintenance, operations, fuel consumption, costs, staff training, and the efficiency of the IT system in processing data) are encouraging, although operating costs seem to have risen, and they enable an assessment of additional, potential environmental benefits (especially in terms of mitigation of emissions toxicity and improvement of the waste management process). Such results are analyzed and commented on, with the objective of advancing knowledge to inform further research studies beyond EBSF_2, in the field of PdM.]]></description>
