A Novel Low-Cost Weigh in Motion (WIM) System Tested in Virginia Suggested the Cost to Monitor Vehicle Weights and Axle Layouts in Live Traffic Could be Reduced by 73 Percent Compared to a Traditional WIM System.

METHODOLOGY The developed RIVIS V1.0 included: sensors (SEN); a data acquisition unit (DAQ); a power supply (PSP); a power source (PSO); and data storage media (DSM). RIVIS V1.0 underwent laboratory…

Auto-Calibration Using Automatic Vehicle Identification Data Tested at Several Weigh-In-Motion Stations in Arkansas Found to Reduce Calibration Costs by 30 to 98 Percent.

METHODOLOGYThe proposed AVI-based auto-calibration method consisted of first, matching AVI-tracked trucks to WIM Per Vehicle Records (PVR), and second, applying a calibration procedure that measures…

Advanced weigh stations with preclearance systems have benefit-to-cost ratios ranging from 8.9:1 to 12.8:1.

RESULTS The table below presents the BCR results for adding low-speed WIM and bypass lane in addition to preclearance system. Note that for basic fixed weigh stations this option includes adding a…
