ABSTRACT
This paper provides a verification of the pavement condition impact on road safety comparing the IRI to the points of occurrence of serious road crashes through two analyses, one using linear graph and the other bar charts containing the average of the IRI values and its standard deviations in a predefined distance. The IRI data was collected though a new technology, SmartIRI application, that required in addition to the mobile phone only a mobile support, to attach the smartphone to the windshield, and an automotive vehicle to drive along the road. The method was tested in a 20 km segment in BR-101 in Pernambuco. It was found difficult to correlate the IRI values with the number of severe road crashes on the segment in both analyses. Despite this, the study shows the relevance of these topics, in addition to successfully presenting a practical way for measuring the IRI.
