Road Owners and Operators: Use of Weigh-In-Motion Technology

Weigh-in-motion (WIM) is a technology that can be used for various private and public purposes.

The BISON system is an intelligent transportation system (ITS) that can weigh vehicles in motion. It measures the weight of the vehicles in transit and other data such as axle loads and spacing, double wheels, vehicle classification, speed and more. The data is provided in real-time through the interface available on any device. 

The BISON system is a high accuracy weigh-in-motion (WIM) system that can be used for various applications such as bridge and viaducts monitoring, protection of road infrastructer and weight overload enforcement.

Data provided by BISON WIM

In addition to the gross vehicle weight (GVW), the BISON system provides other information such as:

Road management and works planning

The information of the load induced by traffic, especially by heavy vehicles is a factor of primary importance, both in dimensioning the sections of pavement and in determining the type of maintenance intervention to be implemented.

Furthermore, with the data provided by the BISON system and by other monitoring sensors, it is possible to establish the relationship between road degradation and transit loads.

Monitoring and protection of bridges and viaducts

BISON dynamic weighing system can be integrated with sensors for monitoring bridges, viaducts and overpasses.
Thanks to the data provided by the weighing in motion it is possible to correlate the structural deformations, detected by the monitoring sensors, with the load on the bridge at a given moment. This feature makes BISON a useful tool for managing heavy traffic and monitoring the impact of heavy traffic on strategic infrastructure of the road network in real-time.

Through an accurate classification of the vehicles based on weight, BISON also allows a more equitable management of the tolls and in advance on the prescriptions of the European legislation that will come into force in 2021 (Direttiva 2011/76/UE).

Public Administrations: WIM for freight traffic
managing and urban roads control

The BISON weigh in motion system WIM system as a tool for controlling access og heavy vehicles to selected parts of the city, so the traffic flows can be improved. 

The the system can automatically identify overloaded heavy goods vehicles and transfer violation notifications to the appropriate law enforcement bodies. Implementing the BISON WIM system public administrations can monitor and reduce the number of overweight trucks on city roads was in order to decrease environmental and noise pollution and to increase road safety.

Traffic management

The BISON Weigh in Motion  system together with appropriate road signs and variable message panels, can give an indication, to vehicles that exceed the weight limits set by bridges and roads, mandatory diversions.

Also linked to road safety, BISON can be used to carry out checks on exceptional transports or on eventual overloads with respect to the weight limit set for critical sections, such as bridges and roads subjected to weight or overloads compared to the limits established by law.

Law Enforcement

The Weigh In Motion system  BISON models 50_10 and 90_10 are approved by the Italian Ministry of Economic Development (Ministero dello Sviluppo Economico) as an automatic functioning weighing instruments i.e. a scale intended for the weighing of moving road vehicles.

”The BISON systems can measure the weight of vehicles, and others information (Speed, number of axles, width, lenght, double tires, etc) with the utmost accuracy, without the need to stop them, thus providing important support to the Law enforcement in the control of heavy vehicles, including exceptional transports. With the WIM system is possible to sanction immediately vehicles that exceed their weight limit or exceed the load limit of bridges and roads.”.

for Logistics and Worksites

LS Control BISON model has been specifically designed to monitor 24/7 access to construction sites, logistics areas, ports, quarries and any other situation in which checking the weight of incoming/outgoing vehicles is essential.

For further site security, for example, it is possible to use personalized statistics with a daily traffic report, including non-accredited license plate alerts.

It can also be integrated with a ANPR camera, allowing plate tracking and cross-referencing information with the data provided by various management matching the measurement to a plate number.

The system allows aggregate statistical data to be obtained by creating a historical archive which can also be consulted remotely.
