Use of FBG sensors for weigh in motion

Techniques able to perform weighing of road vehicles not requiring any lowering of their cruise speed are of great interest for a large amount of applications. Many of such applications are traditionally related to determining custom duties, toll-way fares and cost of paying freight, but new applications often concerned with high-speed travelling vehicles are arising, as for instance the smart management of highway lorry traffic. In this paper we present preliminary results for the development of a weigh-in-motion technique based on Fibre Bragg Grating sensors. The proposed technique is intended for the production of a weigh-in-motion station suitable for high-speed road vehicle and high load resolution
