Pre-Selection on I-84 in Oregon, USA
“…quite impressed with the numbers, especially considering the time of year and condition of the roadway.”
The sensors are installed in the traffic lane with two rows (4 total sensors) per lane. Vehicles crossing the WIM site are diverted to static scales downstream for measuring GVWs. This analysis was conducted with data from the mountains during winter (December).
Comparison of the Class 9 (5 axle) vehicle data shows GVW performance of ±3.6% error at highway speeds compared to static scales, well within COST 323 A(5) and ASTM 1318 Type III requirements.
The WIM Strip Sensors are used for low- and high-speed (LS-WIM and HS-WIM) applications throughout the world.
Weigh-In-Motion Strip Sensors
• Weigh Vehicles at Speeds up to 80 mph (130 km/h)
• Designed to Comply with COST 323 & ASTM E1318-09
• Used in Screening, Enforcement, Data Collection, Tolling & Ports WIM Applications
