Assessment of the road based on PCI and IRI roadroid measurement

Abstract: There are two methods of road assessment, ie, visually and using tools. Visual assessment makes use of the PCI (Pavement Condition Index), while assessment with the Roadroid app can be used to obtain the value of IRI (International Roughness Index) with less cost. Functional assessment of roads in the field more use of visual methods. This method is influenced by the subjectivity of surveyors. Therefore, the assessment using the visual method should be correlated with the assessment method using tools, in orde… Show more

The study defined such drivers as "Research and development (R&D)" sub-pillar (Х 1 ), "Knowledge workers" sub-pillar (Х 2 ), "Innovation linkages" sub-pillar (Х 3 ), and "Knowledge creation" sub-pillar (Х 5 ).…”

“…In order to justify the most significant drivers of international migration of researchers, the study applied the interpretation of the calculated correlation coefficients according to the generally accepted guidelines [30][31][32]. The results of the correlation analysis allowed the scholars to choose four drivers of researchers' migration, which have the greatest impact on the dependent variable (i.e.…”

“…The Pearson correlation between IRI and PCI was À0.23; however, it is considered a weak correlation. This is due to the functional differences between IRI and PCI (Putra and Suprapto, 2018). Sandra and Sarkar (2013) developed a multilinear regression model for pavement roughness based on the density of patching, potholes, rutting and cracking for different severity levels.…”
