Weight Enforcement is vital to minimize the damage caused by overloaded vehicles to roads and highways, and to increase safety for the operators. Detection of these vehicles at high-speeds (HSWIM) is an efficient and effective method for screening for enforcement or pre-selection of vehicles for static weigh stations.
Screening for Enforcement in the United States
Typical Sensor Configuration

Strip sensors for pre-selection or screening for 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 screening for enforcement WIM systems.  COST 323 A(5) and COST 323 B+(7) are commonly referenced for these screening for enforcement sites.  Six sensor (three pairs) have been used in some countries for these applications.
Intercomp strip sensors are also used in data collection, tolling (ETC), ports of entry or departure, and bridge and pavement protection.
