Applications of fiber optics sensors in weigh-in-motion (WIM) systems for monitoring truck weights on pavements and structures.

The main objective of this project was to investigate emerging technologies and to establish criteria for evaluating fiber optic sensors used to measure actual dynamic loads on pavements and structures. The dynamic load of particular interest for this project was the vertical component of the load caused by vehicles as they move over the pavement or structure, which is referred to as weigh-in-motion (WIM). Therefore, this project was aimed at determining the state-of-the-art of fiber optic WIM systems.
