The object of this study was to determine the feasibility of utilizing highway bridges to weigh vehicles in motion. Specifically, the study was to determine the feasibility of developing a total system to acquire, record, and reduce in-motion collected vehicle data, comprising dynamic axle load, dynamic truck load, static axle weight, vehicle weight, number of axles, axle spacing, headway, truck lane of occupancy, truck type, and truck arrival time. Two forms of dynamic load sensors were investigated, direct-contact form which would sense directly from tire contact, and indirect forms, which measured a resultant bridge behavior effect. Study results indicated that a significant test and evaluation effort was necessary before a firm decision could be made on the practicality of using seismic sensors. All of the information collected on the use of seismic sensors was very favorable, but not sufficiently conclusive to commit to the fabrication of a sensor system.
