Weigh in Motion Installation on HIGH SPEED lane
for Viaduct monitoring
Weigh In Motion Installation Video
Weigh In Motion Installation guide on the Viaduct high speed lane.
Modern highway owners, ITS engineers, and enforcement agencies need road-friendly technologies.
They look for systems that install in a single shift and deliver enforcement-grade precision.
The video explains how a fiber optic weigh in motion sensor network becomes a fully working high-speed weigh in motion system in under eight hours.
Beyond the case study, you’ll discover how bridge weigh in motion monitoring powers a dynamic truck weighing system.
The video clearly explains how a fiber optic weigh-in-motion (WIM) sensor network transforms into a fully operational high-speed WIM system in under eight hours.
Beyond this specific case study, you’ll also discover how bridge WIM monitoring can enable a real-time, dynamic truck weighing solution, applicable to a wide range of infrastructures.
In particular, the Molise Viaduct—a key structure along Italy’s A1 corridor, frequently crossed by heavy freight vehicles—served as an ideal test-bed for this next-generation solution.
For this project, engineers selected BISON’s fiber optic WIM sensors for three main reasons:
Firstly, the system requires minimal civil works. Each sensor was installed using a surface cut of just 60 mm—a process that’s fast, clean, and entirely non-invasive.
Secondly, the system delivers high-speed data acquisition. It accurately records axle loads at speeds of up to 130 km/h, making it perfectly suited for busy logistics corridors.
Finally, the solution is built for global enforcement compliance. It integrates seamlessly with automatic overload enforcement systems, and is fully compliant with both EU and U.S. legal standards.
One of the greatest advantages of the BISON weigh-in-motion system lies in its remarkably fast installation.
Whereas traditional WIM systems typically require 2 to 10 days of road closure, along with deep excavation, buried cables, and complex calibration procedures, BISON eliminates all of these obstacles—making the entire process simpler, faster, and more cost-effective.
Here’s what sets BISON apart during installation:
Up to 8 hours of total traffic closure — from the first surface cut to full system activation
No road resurfacing needed — works reliably on pavement with roughness up to 4 mm/m IRI
No buried electrical cabling — all data and power are routed through fiber optic lines, ensuring safety and simplicity
No need for utility checks or special permits — the surface-level installation avoids interference with underground infrastructure
