Abstract:The primary objective of this second phase is the further development, demonstration
and field evaluation of a permanent dual purpose bridge weigh-in-motion and health monitoring
system over an extended period of time. Calibrated test truck results demonstrated that the
proposed algorithm can accurately predict vehicle speeds, and that even if the speed is exact
other factors can contribute to the inaccuracy of the algorithm. The research has also been
applied to a large continuous traffic data-set consisting of 385 days, providing information
including gross vehicle weight (GVW), truck speeds, and average daily truck traffic (ADTT) for certain months. The GVW, speed, and time stamp of
each identified truck has been saved and loaded to a website accessible by the Connecticut
Department of Transportation.
