The Weigh In Motion (WIM) system

BISON Weigh in Motion System: How does it work

BISON WIM technical features

The Weigh In Motion (WIM) system BISON is composed of 2 stainless steel bending plates equipped with fiber optic sensors connected to a datalogger.

The bending plates are installed flush with the road surface and can be placed on urban and suburban roads, motorways / highways, bridge and toll booths.
 
 The Weigh-in-Motion (WIM) system allows to weigh the vehicles in the flow of traffic without any interruption. 
The data is collected and sent in real-time and permits to manage all transits and monitor overload vehicles on the road.

The data acquisition unit (datalogger), processes, and stores all information collected in a database. All the transit information is made available to the user through a web interface easily accessible from every device.

Weigh in motion Software

The software is designed directly from iWIM, it has simple and intuitive and is able to provide, immediately and clear all the necessary information of specific interest to the user.

The system can be interfaced with other ITS systems such as ANPR cameras for license plate recognition.
