Title: Use of Cell Phone Apps to Evaluate Low-Volume Roads in Illinois
Accession Number: 01733257
Record Type: Component
Availability: Find a library where document is available Abstract: Cell phone apps can be used to measure low-volume road roughness as a cheaper alternative to using a high-speed profilometer and the app can be made user-friendly. This study evaluated two Android operating system-based apps, Roadroid and RoadBump, both commercially available, to measure pavement roughness, specifically, International Roughness Index (IRI) of low-volume roads. The measured IRI values were validated with a high-speed laser profiler operated on both smooth and rough local roads. Results indicate that Roadroid provides better IRI data when compared to the RoadBump app that is in reasonably good agreement with the high-speed profilometer data. A consistent IRI dataset on low-volume roads could be achieved if the vehicle was driven within 30 to 50 km/h speeds on both smooth and rough pavements. Dashboard mount with Roadroid app offered the most reliable IRI values. A definite conclusion cannot be made regarding the most suitable vehicle among a sedan car, a van, and a truck on which to mount the cell phone, although the sedan car option often provided somewhat better results in measuring IRI with Roadroid app.
