Abstract
A segment of roadway includes a body having a top surface, a length along a direction of travel that is bisected by a length midpoint, and a width perpendicular to the direction of travel and bisected by a width midpoint. A strain sensor array is embedded in the body and includes a plurality of vehicle-strain sensors having at least one of a length and a spatial resolution along the length dimension of equal to or less than fifty centimeters (50 cm). The plurality of vehicle-strain sensors are configured to detect strain on the body resulting from vehicles traveling across the top surface, and are distributed across the body such that at least thirty percent (30%) of the vehicle-strain sensors are positioned on each side of each of the length and width midpoints.
