Systems for weighing vehicles while they are in motion are in widespread use in many countries. The accuracy of these weigh-in-motion (WIM) systems is strongly influenced by the road profile and vehicle dynamics. Systems based on sensors that are embedded in the pavement or placed on top of the road surface can measure the axle load only for the fraction of a second for which the wheels are present on the sensor. An alternative to pavement WIM systems that increases the length of the load… Expand
Monitoring of Changes in Bridge Response Using Weigh-In-Motion Systems
Weigh-In-Motion (WIM) and Bridge Weigh-In-Motion (B-WIM) are systems that allow obtaining the axle weights of road vehicles in motion, at normal traffic speeds. While WIM employs sensors embedded inExpand
On the use of bridge weigh–in–motion for overweight truck enforcement
Bridge weigh-in-motion (B-WIM) is a method by which the axle weights of a vehicle travelling at full highway speed can be determined using a bridge instrumented with sensors. This paper looks at theExpand
A filtering-based bridge weigh-in-motion system on a continuous multi-girder bridge considering the influence lines of different lanes
TLDR
The fast Fourier transform (FFT) method, which can significantly purify the collected structural responses (dynamic strains) received from sensors or transducers, was used in axle counting, detection, and axle weighing technology in this study. Expand
B-WIM systems application on reinforced concrete bridge structural assessment and highway traffic characterization
TLDR
The results are presented of a B-WIM system applied on a bridge over the Lambari river, located at BR 153 in Uruacu (Goias), which is capable of determining, with good precision, the axle spacing and the gross vehicle weight. Expand

AbstractThis paper proposes a novel Level I damage-detection technique for short- to medium-span road bridges using weigh-in-motion (WIM) technology. The technique is based on the input provided byExpand
Field-calibrated influence lines for improved axle weight identification with a bridge weigh-in-motion system
Bridge weigh-in-motion (BWIM) systems take influence line (IL) as a reference to calculate axle weights. The calibrated ILs based on field measurements can acquire better conformity with the actualExpand
