Auto-Calibration of WIM Using Traffic Stream Characteristics
… evaluates the performance of Weigh-in-Motion (WIM) auto-calibration methods used by the Arkansas Department of Transportation (ARDOT). Typical auto-calibration algorithms compare the WIM measured weights of vehicles from the traffic stream to reference values, using five-axle tractor-trailer …

Field and Modeling Framework for Evaluating Truck Weigh Station Operations
Weigh-in-Motion (WIM) systems improve the capacity of weigh station operations significantly by screening trucks while traveling at high speeds and only requiring trucks within a threshold of a maximum permissible gross of axle weight to be weighed on more accurate static scales. Consequently, the …

Weigh-in-Motion Auto-Calibration Using Automatic Vehicle Identification
<p>Weigh-in-Motion (WIM) sensors are installed on mainline lanes at highway locations to record vehicle weights, axle spacing, vehicle class, travel speed, vehicle length, and traffic volume. These data elements support effective transportation planning, infrastructure design, and policy …

Operational effects of weigh-in-motion systems in weight enforcement
The effects of weigh-in-motion (WIM) systems on traffic operations and weight enforcement were compared and evaluated. The systems studied included high speed WIM, medium speed WIM and conventional static scales alone. The major measurements of effectiveness were traffic delay, queue, and the …

Review of South African live load models for traffic loading on bridge and culvert structures using weigh-in-motion (WIM) data
… of heavy vehicles recorded by weigh-in-motion (WIM) sensors to calculate the load effects on single lane, simply supported structures spanning up to 30m. The main objective was to compare the load effects caused by the recorded vehicles with those calculated using TMH7 Part 2 and the alternative …

Characterization of traffic load and local calibration of the MEPDG for New Mexico
… can only be obtained from Weigh-in-Motion (WIM) data. There are about 15 WIM stations in New Mexico. Data from these WIM sites are evaluated for their use for local calibration of the MEPDG. An algorithm is developed in Visual Basic Application (VBA) to check the quality of WIM data. In …

Untangling compact and diffuse ionized emission toward galactic hii regions
… hydrogen, known as the 'Warm Ionized Medium' (WIM) also exists in the Galaxy. The WIM also emits RRLs and thermal radio continuum. Previous observation of compact \hii regions found two RRL components for many sources, one from the \hii region and the others from the WIM. By observing …

Utah Commercial Motor Vehicle Weigh-in-Motion Data Analysis and Calibration Methodology
… assess the effectiveness of the weigh-in-motion (WIM) system in Utah, the Utah Department of Transportation (UDOT) contracted with a Brigham Young University (BYU) research team to conduct an evaluation of their commercial motor vehicle (CMV) data collection system statewide. The objective of this …
