Weigh-In-Motion system

Weigh-In-Motion (WIM) systems are used on local roads and highways.


Typical system capabilities:

• Vehicle classification;

• Number of vehicle axles identification;

• Vehicle’s individual axle weight measurements;

• Vehicle’s total weight measurement;

• Number of passing vehicles fixation;

• Vehicle speed limit setting;

• Observation of weather and road surface hydrometeorological data.


Typical WIM system’s capabilities and functionality complements the secondary automated systems:

• Video surveillance and capture;

• Vehicle state registration number fixation;

• Vehicle’s bulk fixation;

• Remote data transmission, visualization.


With the help of software WIM data is recorded, analyzed and compared in various aspects:

• Fixation of authorized speed violations facts;

• monitoring and recording if the vehicle gross weight does not exceed the allowable limits;

• According to state registration numbers checking if road taxes are paid;

• Checking insurance companies, technical inspection, border control, customs and other databases;

• Testing of road load, bandwidth, general state of the calculations and projections.
