Vehicle Weight Enforcement with In-Ground WIM Scales
Weight Enforcement is vital to minimize the damage caused by overloaded vehicles to roads and highways, and to increase safety for the operators. Detection and identification of these vehicles is done at low (LS-WIM) and high-speeds (HS-WIM.) WIM is an efficient and effective method for screening and pre-selection of vehicles for static weigh stations, and direct enforcement of weight violations where legislation incorporates Weigh-In-Motion capabilities.

In-Ground WIM Scales Advantages
Permanently installed
Weigh-In-Motion Scales save time by keeping traffic moving while accurately capturing weight related data at entry/exit ports, freight terminals, or toll and commercial weigh stations
- Installation and Maintenance are Less Expensive than Standard Truck Scales
- Collect Weight Data Without Stopping the Vehicle
- OIML R134 Certified

WIM Strip Sensors for Enforcement
Typical Configurations
Weigh-In-Motion Strip Sensors for screening, pre-selection, and direct enforcement incorporate strain gauge sensor technology:
- WIM site installation employs four to six sensors, loop, and electronics
- Consistent Accuracy for Selection of Vehicles from Screening
- Improve Vehicle & Operator Safety
- Simple Integration of Sensors into Existing Enforcement Systems
- Stable readings with environmental fluctuations of temperature
- Minimally invasive in-ground installation
- Does not require frames or drainage
- Maintenance free operation
Regions can have different requirements for accuracy of systems employed in enforcement WIM applications. ASTM E1318, COST 323 A(5) and COST 323 B+(7) are standards commonly referenced for these sites. Four (two pair) or six sensor (three pairs) installations have been used in countries for these applications. Intercomp strip sensors have undergone OIML R134 performance certification testing.
Strip sensors are also used in data collection, tolling (ETC), ports of entry or departure, and bridge and pavement protection.

LS-WIM® Axle Scales for Weight Enforcement
Typical Configuration
LS-WIM Axle Scales use strain gauge technology for low speed enforcement:
- WIM site installation employs single axle scale, loop, and electronics
- High degree of accuracy at low speeds
- Stable readings with environmental fluctuations of temperature
- Small Scale Footprint vs. Static Scales
- Durable Platform Construction
- Simplified Maintenance
At low speed, these scales can meet requirements for accuracy of systems employed in enforcement WIM applications. The Intercomp LS-WIM Axle Scale has undergone OIML R134 performance certification testing.
Intercomp scales are also used in Industrial check weighing, Inventory management, tolling (ETC),
Automated Gate Systems (AGS), and ports of entry or departure.

App Notes for In-Ground WIM Enforcement Scales
WIM Sensors for Pre-Selection
Weigh-In-Motion (WIM) information is used in the mainline when screening for enforcement or pre-selection prior to diverting vehicles for static weighing. In the United States, static weights are used for direct enforcement, and direct data comparisons demonstrate the performance of strain-gauge based WIM sensors coupled with static scales utilizing the same highly accurate technology.
WIM Strip Sensors are comparable to piezo quartz scales for pre-selection and pre-enforcement applications.
Strip Sensors for HS-WIM Direct Enforcement
Transportation departments, ministries of transportation, and enforcement officials throughout the globe rely on High-Speed Weigh-In-Motion systems for law enforcement purposes. Depending on local enforcement laws, Intercomp’s High-Speed Weigh-In-Motion Strip Sensors are a robust and dependable option for enforcement purposes, with OIML R134 certification to support use in countries that use OIML as reference for their HS-WIM direct enforcement standards.
