In the PAVE-SCAN ecosystem (Figure 1), low-cost sensor devices are used for continually assessing the quality of roadway pavements and transferring relevant information to the specialized PAVE-SCAN platform for knowledge extraction and geospatial mapping, subsequently utilised for improved O&M, reduced tailpipe emissions, and improvements in the driving safety and quality of ridership. The proposed EGNSS-compliant sensor system (of which a currently in-use prototype is shown in Figure 2) will be fitted to probe vehicles and buses, brought to EU-wide use through at least four variants (one for Agencies operating the street networks, one for Bus Operators, one for Consulting Organizations, and one for the wider public), and served to interested users through a Product-as-a-Service (PaaS) model.

PAVE-SCAN’s overall methodology will unfold in six interrelated project phases (as listed in Table 2), while its system architecture is shown in Figure 3. The project methodology complies with the ‘do no significant harm’ principle as per Article 17 of Regulation (EU) No 2020/852 on the establishment of a framework to facilitate sustainable investment (i.e., the so-called ‘EU Taxonomy Regulation’), as the methodology is designed in a way it is not significantly harming any of the six environmental objectives of the EU Taxonomy Regulation.
