Weigh vehicles in motion.
Road protection, enforcement & weight control.
BISON is a fiber-optic weigh in motion system that measures gross weight, axle load, speed and vehicle class in real time—from 5 to 150 km/h. Built for road protection, enforcement and reliable weight control.

Overload control, enforcement, traffic data & statistics.
Use weigh in motion truck scales, weigh in motion weighbridge configurations and connected sensors for road protection, bridge protection, traffic monitoring and heavy-vehicle statistics.
Overload control & enforcementPre-select or directly identify non-compliant heavy vehicles.
Highways, tolling & traffic dataMonitor axle loads, vehicle classes and traffic statistics without interrupting the flow.
Ports, logistics & truck scalesControl incoming and outgoing commercial traffic automatically.

Weigh-in-motion in real road conditions
Protect roads before overload becomes damage.
From the road surface to the control room, every part of the iWIM ecosystem is designed around the reality of live traffic.
Overload control
Make hidden axle loads visible before they become infrastructure damage.
Bridge protection
Connect traffic loads with structural response.
Live intelligence
Turn every passage into an operational record.
Fiber-optic weigh in motion sensors inside the road
Fiber-optic sensors inside the road.
No road damage, no weather dependence, and reliable performance in hot climates, water and salt.
01
Fiber-optic sensors inside the road
Passive sensing with no electronics under the pavement, strong immunity to electromagnetic interference and stable measurement in demanding environments.
02
No damage. No weather dependence.
Stainless-steel plates and fiber optic sensors keep working through heat, water, salt, snow and mud—without relying on dry weather conditions.
03
Reusable plates for road works and resurfacing
Plates can be removed, reused and reinstalled after road works, while the datalogger delivers real-time weight, axle, speed, classification and overload data.
Software included in the weigh in motion system
Custom WIM software for vehicle classification and ITS integration.
BISON software is included in every weigh in motion system. It is based on software already developed by iWIM and customised for each project, with vehicle classification adapted to the classes used in each country. The platform provides weight, axle, speed, overload and traffic statistics, and remains open to any existing or new ITS device, including ANPR cameras, context cameras and LiDAR.
52.4 t
One passage. One complete record.
Instant overload assessment.
5 axles
Axle-by-axle detail.
Know where the load is.
26 km/h
Measured in the traffic flow.
No stopping, no bottleneck.
Class 5
Vehicle type and national class.
Automatic classification.
