New generation of dynamic Weigh-in-Motion

World's first free-flow dynamic scale for weigh-in-motion OptiWIM® can measure the weight of passing vehicles with high accuracy regardless the wheel position and direction. This unique ability eliminates possible violation and irregularities and makes the device the first one of its kind as the inability of measurement in the whole width of the road is the most crucial weakness of current technologies.



  • World first free-flow dynamic weights system
  • Fiber-optic technology
  • Highest possible accuracy
  • Direct vehicle width measurement
  • Double-tyre detection
  • Direct detection of underinflated tyres
  • Easy installation and maintenance via U-Bed
  • 10 year lifespan
  • Toll-per-Tonne ready

OptiWIM Sensor

New WIM functions

The OptiWIM® sensor offers new and useful features thanks to its design and technology. The sensor can measure the vehicle’s axle width directly. It is also able to detect the use of double-wheel assemblies or the presence of underinflated tyres, even in dual-assembly, separately.

Direct Width Measurement

New field of WIM applications

The OptiWIM® solves the problems of today´s Weigh-in-Motion systems which are at their physical limits. OptiWIM® represents a new generation of WIM that fully enables rapid development of direct enforcement and opens a new category of required tolling application Toll-per-Tonne.

OptiWIM® is a world first WIM:


… for Direct Enforcement with the highest possible accuracy

OptiWIM® can also be used for automatic penalisation of overloaded vehicles. The advantage lies in the measuring ability in the full width of the roadway as well as in the higher accuracy compared to the previous generation of sensors.

Thanks to automatic ticketing there has been a substantial improvement in enforcement and penalisation of violators. Furthermore, the roads' protection from overloaded vehicle damage has been achieved. This has increased the roads' lifespan dramatically and has led to significant savings on repairs.

… that fully enables Toll-per-Tonne applications

Due to the fact that the OptiWIM® sensor not only weighs vehicles but also measures their width, it is also able to determine with high accuracy whether the vehicles use the weight distribution correctly on individual axles. The system is capable of detecting such overloads as well as underinflated tyres, even in dual tyre assembly separately.

With the precise weight assessment regardless the point in which the vehicle passes OptiWIM® can be considered an optimal solution for the system of toll fees calculation per the exact weight of each vehicle and its load. Since the device is the only one able to capture the weight in any part of the road, it is the world’s first sensor enabling the free-flow-toll-per-tonne solution that would create automatic toll system based on fair conditions with low chances of violations.
