What Is Weigh-In-Motion (WIM)?

Weigh-In-Motion (WIM) is a technology used to measure axle loads, gross vehicle weight, vehicle classification, and speed while the vehicle is in motion—eliminating the delays and inefficiencies of traditional static weighing.

Using a combination of road-embedded sensors, high-definition cameras, and intelligent analytics, WIM systems provide reliable, fast, and accurate weight data that supports a variety of transportation.

• Overload enforcement.
• Highway asset protection
• Traffic data analysis
• Freight monitoring
• Revenue protection
• Smart mobility planning
