Contactless Bridge Weigh-in-Motion [PDF]
Journal of Bridge Engineering, 2016 AbstractBridge weigh-in-motion (WIM) uses existing bridges to find the weights of vehicles that pass overhead. Contactless bridge weigh-in-motion (cBWIM) uses bridges to weigh vehicles without the need for any sensors to be attached to the bridge. A camera is mounted on the back of a telescope, which magnifies the image to the extent that submillimeter

Radio and Electronic Engineer, 1969 In recent years, a great deal of effort has been applied to the development of methods for weighing objects in motion. In this paper, sources of error associated with dynamic weighing are outlined and various approaches to the problem are described with estimated results.

Identifying damage on a bridge using rotation-based Bridge Weigh-In-Motion [PDF]
, 2020 Bridge Weigh-in-Motion (B-WIM) systems use the bridge response under a traversing vehicle to estimate its axle weights. The information obtained from B-WIM systems has been used for a wide range of applications such as pre-selection for weight ...

Estimation of Extreme Load Effects on Long-Span Bridges Using Traffic Image Data
The Baltic Journal of Road and Bridge Engineering, 2018 This paper proposes an algorithm for the estimation of extreme intensity of traffic load on long-span bridges. Most Weigh-in-Motion technologies do not operate in congested conditions which are the governing cases for these bridges.

Railway Bridge Weigh-in-Motion System
Transportation Research Procedia, 2016 AbstractThe paper provides an overview of the development of a railway bridge weigh-in-motion (B-WIM) system, one of the first of its kind for weighing trains in motion. A steel truss bridge in Poland was used for testing the system. Four trains which passed over the bridge were weighed in a rail yard in Warsaw.

Direct Measurement of Dynamics in Road Bridges Using a Bridge Weigh-In-Motion System
The Baltic Journal of Road and Bridge Engineering, 2013 A method is presented of measuring a bridge’s characteristic allowance for dynamic interaction in the form of Assessment Dynamic Ratio. Using a Bridge Weigh-in-Motion system, measurements were taken at a bridge in Slovenia over 58 days.

Error Reduction for Weigh-In-Motion [PDF]
, 2009 Federal and State agencies need certifiable vehicle weights for various applications, such as highway inspections, border security, check points, and port entries. ORNL weigh-in-motion (WIM) technology was previously unable to provide certifiable weights, due to natural oscillations, such as vehicle bouncing and rocking. Recent ORNL work demonstrated a
