How does BISON weigh-in-motion work

STAINLESS STEEL BENDING PLATES
The Weigh In Motion (WIM) system BISON is composed of 2 stainless steel bending plates, nstalled flush with the road surface and can be placed on urban and suburban roads, motorways / highways, bridge and toll booths.

FIBER OPTIC SENSORS
The bending plates are equipped with fiber optic sensors and connected by fiber optic cable to the datalogger.

DATALOGGER
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.

Technical features
- OIML R134 CERTIFICATED
- COMPLIES WITH THE COST 323 B+(7)
- NO ELECTRICITY UNDER THE PLATES
- FIBER OPTIC SENSORS
Weigh in motion, data collected
BISON, in addition to the weight, is able to supply the following data without additional devices:

Gross vehicle weight (GVW)

Transit speed

Vehicle counting and classification

Number of axles

Single wheel weight

Axle spacing

Axle width

Vehicle length

Twinned wheels

Alert transit out of one bending plate

WIM 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.

Weigh in motion system applications:
- Bridge and viaduct health monitoring
- Road maintenance works programming
- Collaboration with police and preselection
- Heavy transport statistics
- Real time network traffic monitoring
- Road safety improving
