    Mainline Weigh-in-Motion (WIM)
    Posted:June 20, 2016

    Mainline WIM systems are commonly used to screen vehicles on the mainline for weight compliance as they approach a weigh station. The WIM scale or sensor embedded in the pavement automatically weighs vehicles and provides an estimate of the vehicle's weight to station personnel for sorting purposes. These sensors compare the readings to a weight pass/fail threshold set to a percent of the legal weight. Trucks that exceed the threshold are directed into the weigh station to be weighed on more accurate static scales used to write citations. In addition, LPR Cameras verify tag registration (whether it's valid, expired or suspended), IRP (International Registration Plan), IFTA (International Fuel Tax Agreement), Safety violations and out-of-service violations. USDOT Cameras check for overdue citations via the Florida Department of Highway Safety and Motor Vehicles hotlist database. Mainline WIM devices result in low probability of incorrectly sorting a truck to the weigh station and improves efficiencies by keeping the motor vehicles in commerce. Florida currently has three mainline WIM sites, these sites are located at the port of entry locations (Pensacola I-10, White Springs I-75 and Yulee I-95).
