Weight In Motion (WIM)

High-Speed Autonomous WIM Systems 


SMS provides the most accurate WIM system currently available.  The system was designed by one of the worlds leading experts in software, hard and applications.

Successfully implemented in the US, Brazil, and South Korea, our weigh-in-motion system is designed to measure and record critical data from trucks as they drive over a road embedded sensor. The weight measurements are typically accurate to within 2-3% in all classes and use only the longest-lasting, completely autonomous sensors. A lane-wandering-sensor feature makes it so overweight vehicles cannot skirt around the weight sensors. This system measures: 

  • Vehicle Speed 

  • FHWA classification 

  • Gross vehicle weight (GVW) 

  • Axle weight, axle configuration 

  • Tire position
