Experimental results on a portable, low speed fiber-optic weigh-in motion system are described that demonstrate the applicability of fiber-optic-based sensors in transportation, defense, and law enforcement applications where accurate weight determination of moving vehicles is necessary. Results are given on the systems' dynamic range (0.1--30 metric tons), velocity range (up to 5 km/h), accuracy error (0.5--3.0%), and repeatability. Also included in the paper is a discussion of the sources of error associated with low-speed weigh-in-motion systems and methods of minimizing these errors for practical deployment.
