The research was conducted as a pilot project for Peoria County, Illinois, to collect the International Roughness Index (IRI) data using the cell phone app Roadroid. Two cell phones, Samsung J3 and Motorola G6, were used with dashboard mounts to check the IRI data’s consistency. A Toyota Prius sedan car was used to host the cell phones for collecting IRI data. Eighty-two county roads were surveyed. Concurrently, a survey team of two inspectors collected pavement distress data for computing the Pavement Condition Index (PCI) for the same roads. For each road, four runs were made to collect the IRI data—the roads were surveyed in each of the two directions, using the two different cell phone models. The results indicate a strong relationship between the IRI value collected using the two different cell phones with an R-square value of 0.8087. The comparison suggests that the Roadroid app performed well to measure all levels of distressed pavements for most of the pavements surveyed in this study. However, the cell-phone-measured IRI data does not correlate with the PCI data collected for the same roads.
