Reevaluating how we assess and repair roadways
Pavement condition index or PCI is a measure of pavement distress on a scale of 0 to 100, calculated from visual assessment on a sample of road networks . The standard was originally developed in the 1970s by U.S. Army Corps of Engineers. The PCI relies on city employees manually surveying city streets using a prescriptive manual that contains a visual reference of various pavement distresses and street defects. These employees often undergo some training prior to surveying city streets. Regardless of training or expertise, these visual measurements are subject to inconsistencies and error. Furthermore, the PCI is often conducted on a sampling of city streets and not the entire street grid. To that end any repair or maintenance intervention premised on these measurements is not representative and not equitable.
