Abstract
A roadway segment includes a body having a length along a direction of travel, a width along a width axis, and top and bottom halves along a depth axis. The segment also includes a strain sensor array with one or more optical fiber cables embedded in the bottom half of the body. The strain sensor array includes vehicle-strain sensors configured to detect strain on the body resulting from vehicles traveling across the top surface. The segment also includes a processor that operates the plurality of vehicle-strain sensors at a resolution of not greater than one picometer (1 pm). Any segments of the optical fiber cable(s) that intersect are separated from one another depth wise by at least two-tenths of an inch (0.2 in.). Each of the sensors is separated from each other along the width axis by at least two inches (2 in.).
